High-capacity modular battery storage for homes, farms and small commercial sites

LiFePO4 Australia is currently reviewing the Dyness STACK100 Pro as a potential future product for Australian customers who need a serious, expandable battery system with strong safety features, high-capacity options and a weather-resistant design.

The STACK100 Pro is a high-voltage lithium iron phosphate battery system designed for larger residential, rural, off-grid, backup and small commercial energy storage applications. It has recently been listed by the Clean Energy Council, supporting its use in the Australian market and helping installers and project partners meet local certification expectations.

Dyness STACK100 Pro Battery System — Coming Soon to Australia

Why we are interested in the Dyness STACK100 Pro

Many Australian homes and businesses are moving beyond small 10–15kWh battery systems. With larger solar arrays, higher daytime energy use, electric vehicles, workshops, pumps, air conditioning, machinery and time-of-use tariffs, many customers now need a battery system that can scale properly.

The STACK100 Pro is interesting because it is designed as a modular stacked system, starting from around 15.36kWh and scaling up to 76.8kWh per cluster, with the ability to parallel up to 12 clusters for larger systems up to approximately 921kWh.

That makes it potentially suitable for:

  • Large homes with high energy use
  • Farms and rural properties
  • Small commercial buildings
  • Workshops and sheds
  • Solar self-consumption
  • Backup power systems
  • Peak shaving
  • Load shifting
  • Energy trading and grid-support applications

Built for Australian conditions

One of the standout features of the STACK100 Pro is its IP66-rated enclosure. This is important in Australia because battery systems are often installed in garages, carports, plant rooms, sheds, covered outdoor areas and sometimes tougher site environments.

An IP66 rating means the enclosure is designed to provide strong protection against dust and powerful water jets. In practical terms, this gives installers and customers more flexibility when selecting a suitable installation location, subject to Australian standards, manufacturer instructions and site-specific electrical design.

Dyness has promoted the STACK100 Pro as suitable for indoor and demanding outdoor environments, with a design aimed at harsh local conditions.

Quality battery chemistry: lithium iron phosphate

The STACK100 Pro uses lithium iron phosphate battery chemistry, commonly known as LiFePO4 or LFP. This is the chemistry we generally prefer for stationary energy storage because it is known for strong thermal stability, long cycle life and good suitability for solar battery applications.

According to published product information, the STACK100 Pro uses 5.12kWh battery units and is listed with a cycle life of more than 8,000 cycles at 95% depth of discharge.

For customers, this means the system is designed for frequent daily cycling, which is exactly what you want from a solar battery used for self-consumption, time-of-use optimisation or backup support.

Scalable from residential to commercial

A small battery system can be fine for basic backup or evening use, but it can quickly become undersized for properties with large loads.

The STACK100 Pro is designed to scale. A single cluster can be configured from approximately 15.36kWh to 76.8kWh, and larger installations can use multiple clusters in parallel.

This gives customers a more flexible pathway:

You can start with a properly sized system today, then potentially expand later if your energy use increases, your solar system grows, or your site adds larger loads such as EV charging, refrigeration, pumps, air conditioning or machinery.

Dyness also states that the system supports module mixing within a three-year window, which may help with lifecycle flexibility when expanding a system.

Fast charge and discharge capability

The STACK100 Pro is listed with 1C charge and discharge capability, making it suitable for applications where the battery needs to respond quickly to changing loads or electricity pricing conditions.

This may be useful for:

  • Peak shaving in commercial sites
  • Running larger household loads
  • Supporting backup loads
  • Charging during cheap electricity periods
  • Discharging during expensive tariff periods
  • Future energy trading or VPP-style applications, where supported by the inverter and retailer

Actual charge and discharge performance will depend on the inverter, site design, grid approval, wiring, configuration and battery sizing.

Quiet, practical and installer-friendly

For residential customers, noise matters. The STACK100 Pro has been described as having fanless natural convection cooling, which supports quiet operation in suitable environments.

The system is also promoted as having a plug-and-play stackable design, with Dyness stating that a single cluster installation can be completed in as little as 30 minutes under suitable conditions.

That does not mean every installation is simple. Australian battery installations still require correct electrical design, compliant isolation, inverter compatibility checks, switchboard assessment, backup circuit planning, DNSP approval where required, and installation by appropriately qualified professionals. But a well-designed stackable battery system can reduce on-site complexity compared with traditional rack systems.

Safety features

Safety is one of the main reasons we are interested in this product. Dyness promotes the STACK100 Pro with a five-layer safety protection system and has described the system as having advanced safety features for indoor and demanding outdoor environments.

The broader STACK100 product information from Dyness also refers to module-level safety features and fire protection concepts, including independent fire extinguishing arrangements in the battery pack design.

As with all battery systems, final suitability depends on the exact model supplied in Australia, the installation location, applicable standards, inverter pairing, battery clearances, enclosure requirements and manufacturer documentation.

Potential applications

Large residential solar battery systems

For homes with large solar systems and high electricity bills, the STACK100 Pro may provide enough storage to shift a meaningful amount of solar energy into the evening and night.

It may be suitable for customers who want more than a basic battery and are looking for a larger, more expandable energy storage platform.

Backup power

When paired with a compatible hybrid inverter and correctly designed backup circuits, a large battery system can help keep selected loads running during outages.

Backup performance depends heavily on inverter capability, battery size, surge loads, wiring design and whether the system is configured for partial-home or whole-home backup.

Farms and rural properties

Rural sites often have high energy demands, pumps, sheds, refrigeration, workshops or unreliable grid supply. A scalable high-voltage battery can be useful where standard residential batteries are too small.

Small commercial and industrial sites

The STACK100 Pro may suit businesses that want to reduce peak demand charges, store solar energy, improve resilience or shift energy use away from expensive tariff periods.

Deye Review 2026 and Beyond Products and Features

Here is a comprehensive and technical deep dive into DEYE’s newest lineup of hybrid inverters and all-in-one energy solutions, based on the insights revealed at their recent All-Energy showcase.

DEYE’s Next-Gen All-In-One Hybrid Inverter Ecosystem

The energy storage and hybrid inverter landscape is shifting rapidly from modular, decentralized components to highly integrated, all-in-one ecosystem architectures. DEYE, a manufacturer heavily embedded in the global solar market (often white-labeled under various brand names), has unveiled its next generation of hybrid energy systems.

Moving far beyond simple solar inversion and battery charging, DEYE’s new hardware operates as a holistic Energy Management System (EMS). Let’s break down the technical specifications and architectural advantages of their latest product suite.

1. Smart Load Integration & LoRaWAN Connectivity

Most traditional inverters focus purely on supply-side metrics—managing generation and storage. DEYE’s new generation flips this by actively controlling demand-side loads.

The new inverters feature a built-in EMS with natively integrated LoRaWAN (Long Range Wide Area Network) protocols.

  • Complete Wireless Control: Using LoRaWAN wireless dongles, the inverter can communicate with remote hardware—like EV chargers, smart relays, and smart meters—up to 200 meters away without requiring physical cable runs.
  • Network Independence: Unlike typical IoT smart home ecosystems, DEYE’s communication protocol does not rely on the customer’s local Wi-Fi router. The inverter creates its own self-contained mesh, ensuring uninterrupted load control (e.g., scheduled EV charging based on Time-of-Use tariffs or excess PV production) even during localized network outages.

2. The “All-in-One” Residential Solution: The Inverter is now built in to the stack

DEYE Low Voltage Residential All in one BESS 1P 10kW

With Inbuilt Inverter

48v Lithium Battery Australia CEC
With External Hybrid Inverter

For residential applications, DEYE has introduced a highly stackable “All-in-One” unit that supports both on-grid and full off-grid topologies.

  • Inverter Ratings: The range supports single-phase models from 3.6 kW up to 8 kW, and three-phase models from 5 kW up to 12 kW.
  • Storage Density: The system utilizes low-voltage 5.12 kWh battery modules. A single stack can accommodate up to 6 modules (approx. 30 kWh).
  • Massive Expandability: You can parallel up to 6 of these battery clusters to a single inverter, pushing the maximum localized storage capacity to an impressive 180 kWh.
  • The “6-in-1” Architecture: DEYE classifies this as a 6-in-1 unit, most notably featuring direct diesel generator integration. The inverter can dynamically control a generator start/stop relay based on State of Charge (SoC) parameters, making it an ideal candidate for off-grid and rural properties.

3. Integrated Gateway & Ultra-Fast Islanding (4ms)

A major pain point in standard whole-home backup installations is the requirement for a separate external gateway or Automatic Transfer Switch (ATS)—such as the Tesla Backup Gateway. These external units are necessary to physically decouple the home from the grid during blackouts to ensure compliance with anti-islanding regulations (zero export).

DEYE has built this gateway hardware directly into the inverter chassis.

  • Fewer Points of Failure: This native integration reduces installation time, minimizes required wall real estate, and eliminates the need for third-party ATS wiring.
  • 4-Millisecond Transfer Time: In the event of a grid failure, the inverter detects the voltage drop and switches to off-grid backup mode in just 4 milliseconds [04:07]. This UPS-grade transfer time is fast enough to keep sensitive electronics, servers, and desktop computers running without rebooting.

4. Unmatched Phase Paralleling Architecture

Where DEYE truly flexes its engineering muscles is in its master/slave paralleling capabilities, which treat subsequent inverters as modular power blocks rather than isolated systems.

  • Single-Phase: Up to 16 inverters can be paralleled together.
  • Three-Phase: Up to 10 inverters can be paralleled together.

Crucially, the backup (EPS) ports can also be paralleled [06:01]. If an 8 kW single-phase inverter isn’t sufficient to handle the inrush current of a home’s HVAC system during a grid outage, you can parallel multiple units to stack their continuous backup output. The architecture allows you to easily expand the system’s power ceiling retroactively as site requirements grow.

5. C&I (Commercial & Industrial) Muscle

Scaling up from the residential sector, DEYE is rolling out heavy-duty solutions for the C&I market, maintaining the exact same modular philosophy.

BOS-G Pro- New Model

BOS G Pro 16x5kwh 82kwh
  • BOS-G Pro High-Voltage Batteries: Utilizing 5.12 kWh modules, these high-voltage batteries can be stacked up to 12 per rack. You can tie up to 16 racks together, bringing total storage capacity to just under 1 Megawatt-hour (MWh).
  • 80 kW Three-Phase Hybrid Inverter: These massive storage arrays mate to DEYE’s pending 80 kW hybrid inverters. Mirroring the residential lineup, up to 16 of these 80 kW units can be run in parallel, easily pushing the system into the multi-megawatt operational tier [06:51].
  • Note: DEYE also noted that a massive 300 kW utility-scale inverter is currently navigating the compliance paperwork.

Summary

DEYE is aggressively targeting the pain points of modern solar installers and system architects. By bringing the EMS, grid gateway, and LoRaWAN communications inside the inverter casing, they are cutting down on physical clutter while offering an incredibly resilient, UPS-grade backup solution. Whether it’s an 8 kW off-grid cabin or a 1 MWh commercial facility, their paralleling architecture allows for virtually unlimited scaling.

How to Connect a JK Inverter BMS to Victron

Victron + JK inverter BMS guide

How to connect a JK Inverter BMS to a Victron GX system

This guide is for JK PB-series / JK Inverter BMS models with CAN communication, connected to a Victron GX device such as a Cerbo GX, Ekrano GX, Venus GX, or Venus OS system.

CAN communication Victron GX DVCC LiFePO4 battery systems

Best connection

Use CAN from the JK inverter BMS to the Victron GX device. This is the cleanest setup for a managed lithium battery because the GX device can receive charge and discharge limits from the BMS.

Main thing to avoid

Do not assume a normal Ethernet cable is correct. The RJ45 connectors look familiar, but the CAN pinout is not standard Ethernet.

Exact model matters

JK hardware revisions and app labels can differ. Always verify the CAN port, cable pinout, and protocol setting for the exact BMS you are installing.

Safety note: this is a communication guide, not a complete battery build guide. Battery assembly, fusing, isolation, earthing, enclosure design, firmware, inverter settings, and local electrical rules still matter. If you are not sure, have the system checked by a suitably qualified person.

What this connection actually does

When the JK BMS is communicating properly over CAN, the Victron GX device can see the battery as a managed lithium battery. With DVCC enabled, the GX device can use BMS-provided limits such as charge voltage limit, charge current limit, and discharge current limit.

In practical terms, this lets the BMS tell Victron equipment when to charge harder, slow down, or stop. It is a better approach than relying only on fixed charge voltages inside the inverter or MPPT.

Recommended wiring approach

For current JK inverter BMS setups, the usual recommendation is a Victron VE.Can to CAN-bus BMS Type B cable, Victron part number ASS030720018. Some users report that Type A can work because CAN-H and CAN-L are the same and the ground is less critical, but Type B is the cleaner starting point for JK inverter BMS.

FunctionVictron GX sideJK inverter BMS sideNotes
CAN-HPin 7Pin 4CAN high signal.
CAN-LPin 8Pin 5CAN low signal.
GNDPin 3Usually pin 2 for Type BSome JK documents/variants show different ground references. Verify before crimping.
Important: if making your own cable, test continuity before plugging it into equipment. Many JK/Victron communication problems are cable, port, or protocol-selection problems rather than a faulty BMS.

Step-by-step setup

  1. Confirm the correct JK port

    Use the JK BMS CAN port, not the RS485 port. On some JK documentation or hardware revisions, labels and port order have caused confusion, so check the manual and look for CAN traffic if the GX does not detect the battery.

  2. Connect the CAN cable

    Connect the JK CAN port to the Victron GX CAN port intended for managed batteries. On older Cerbo GX units, this is commonly the fixed BMS-Can port. On newer GX devices, the VE.Can ports may be configurable.

  3. Set the JK protocol

    Open the JK app, enter settings, and set the inverter/CAN protocol to the Victron CAN protocol. On many JK PB models this is shown as Victron or protocol number 4. Restart the BMS after changing protocol.

    Watch the JK app protocol setting walkthrough here without leaving this guide.

  4. Configure the Victron CAN port

    On the GX device, go to the CAN port settings and set the relevant port to a BMS/CAN profile at 500 kbit/s where applicable. Older Cerbo GX BMS-Can ports are fixed at 500 kbit/s.

  5. Check the GX device list

    Return to the device list. If communication is working, the battery should appear as a connected BMS/battery device. Check that voltage, current, SOC, and limits look sensible.

  6. Enable DVCC

    Enable DVCC/Charge Control on the GX device so Victron chargers and inverter/chargers can follow BMS-provided limits. Confirm charge voltage limit, charge current limit, and discharge current limit are being received.

DVCC settings to check

With a managed CAN-bus battery, the key is not to manually force charge voltages everywhere. The BMS should be sending limits and the Victron system should be following them.

  • DVCC / Charge Control enabled.
  • Battery appears in the GX device list.
  • CVL, CCL and DCL values look realistic.
  • Charge current limits are not higher than the battery, wiring or BMS can safely support.
  • Any manual voltage limiting is intentional and understood.

Troubleshooting

The BMS is not showing up on the Victron GX device
  • Confirm you are plugged into the JK CAN port, not RS485.
  • Confirm the JK protocol is set to Victron CAN / protocol 4 where applicable.
  • Confirm the GX CAN port is set for the correct BMS/CAN profile and speed.
  • Try a known-good Type B cable or continuity-test your custom cable.
  • Check termination on the CAN bus.
The battery appears but charge control does not seem right

Check that DVCC is enabled and that the GX device is receiving CVL, CCL and DCL from the battery. Also check whether any manual charge voltage/current limits are overriding or reducing what you expect.

I have multiple JK batteries in parallel

Normally one master BMS communicates with the Victron GX device, while the JK batteries communicate with each other using the JK parallel/RS485 arrangement. Addressing must be set correctly. Follow the JK manual for your exact model.

Can I use RS485 or Bluetooth instead?

For a serious 48V Victron power system, wired CAN is the preferred path when the JK inverter BMS supports it. RS485 or third-party Venus OS drivers can be useful for some older/non-inverter BMS models, but they are not the cleanest first choice for a managed battery system.

Useful references

Need help choosing the right JK, Victron or LiFePO4 battery setup?

If you are building a 48V battery system and want it to communicate properly with Victron, it is worth checking the BMS model, battery design and cable choice before ordering parts.

The Ultimate 2026 Home Battery Guide: Comparing Sigenergy, GoodWe, Deye, RUIXU and More Before the Rebate is reduced

Here’s the updated post May 1st 2026 Home Battery Guide

The Ultimate 2026 Home Battery Guide: Comparing Sigenergy, GoodWe, Deye, RUIXU and More – What the May 1 Rebate Changes Mean for You

The “May 1st” Reality Check – What Changed

The Federal Government’s Cheaper Home Batteries Program underwent its biggest overhaul on May 1, 2026. The changes create a “Double Squeeze” for larger systems:

  1. STC Factor Drop: The multiplier fell from 8.4 (Jan–Apr 2026) to 6.8 (May–Dec 2026).
  2. Size Tapering: Rebates are now tiered by usable capacity:
  • 0–14 kWh: 100 % of the STC factor
  • >14–28 kWh: 60 % of the STC factor
  • >28–50 kWh: 15 % of the STC factor

This significantly reduces support for high-capacity systems. The rebate on capacity above 28 kWh is now only about 15 % of the (already lower) base rate.

Important note: The rebate is based on the installation/commissioning date. While the highest-rebate window has closed, the program continues with further step-downs every six months.

The Contenders: Individual System Reviews

  1. Sigenergy SigenStor (10kW / 40kWh)
    The Innovation Leader
    The world’s first “5-in-one” system integrates the inverter, battery, and optional DC EV charger into one sleek stack. It’s premium-priced, but the software and user experience are excellent.
  • Tech: Uses 8kWh modules with high-grade cells; standout V2X readiness for future EV-to-home power.
  • Safety: “Sigen Shield” aerosol fire suppression in every module.
  • Best For: Premium homeowners wanting an advanced, “Apple-like” experience and EV integration.
  • Considerations: Higher upfront cost often means a longer payback period. Many buyers find better pure value in other systems for everyday self-consumption.
  1. GoodWe ESA Series (9.99kW / 40kWh)
    The Reliable Workhorse
    GoodWe is a trusted name in Australia with over a decade of local presence. The ESA is a straightforward all-in-one tower focused on simplicity and strong backup performance.
  • Tech: 63A bypass for near-whole-home backup; UPS-level switching speed (<4ms).
  • Safety: Internal aerosol fire suppression at module level.
  • Best For: Families who prioritise reliable blackout protection on stable grid networks.
  • Important Limitation (per official GoodWe ESA User Manual): In off-grid/backup mode the ESA limits motor and inductive loads (air conditioners, pool pumps, refrigerators with compressors, etc.) to approximately 30 % of the inverter’s nominal power. This makes it excellent for short grid outages but less suitable for full or prolonged off-grid operation compared to Deye or Sigenergy systems.
  • Compare with Sigenergy: Similar capacity and safety without the premium (often unnecessary) DC charger. For a detailed side-by-side, call 07 4191 6815.
  1. Deye 10kW LV + RUIXU Lithi2-16 (48kWh)
    The “Tank” System – Preferred for Full or Semi-Off-Grid
    Pairing a robust Deye low-voltage inverter with multiple RUIXU Lithi2-16 modules creates an industrial-grade powerhouse.
  • Tech: The Deye inverter stands out for its excellent full off-grid capability, including seamless generator support (it can automatically start and synchronise with a backup generator to charge batteries and power loads when solar and battery are insufficient — a feature many pure hybrid systems handle less effectively or require extra components for). The RUIXU batteries offer 9,500+ cycles (far above the ~6,000 of many competitors), built-in heaters for cooler climates, and individual LCD touchscreens.
  • Safety: Aerosol fire suppression in every module.
  • Best For: Rural or remote properties needing full or semi-off-grid performance, heavy daily cycling, or long-term reliability in areas with unreliable grid supply.
  • Considerations: This setup is generally less suitable for typical city or regional grid-connected homes, where simpler hybrid systems (like GoodWe or Sigenergy) are often more cost-effective and easier to integrate with existing grid export rules. It shines in off-grid or high-demand scenarios but can be overkill (and more complex) for standard urban installs.
  1. Dyness Cygni
    The Value/Capacity Specialist
    Dyness offers high-density storage that’s easy to scale.
  • Tech: 1C charge/discharge rate (full capacity in ~1 hour) — excellent for capturing solar spikes or heavy evening loads. Space-efficient design, well-suited for indoor/on-grid installations.
  • Best For: Large homes with high energy use seeking maximum storage at a mid-tier price.
  • Important Limitation (per official Dyness Cygni User Manual): In off-grid/backup mode, inductive/motor loads are restricted (supports a 2P non-inverter air conditioner as an example), and total capacitive loads should not exceed 0.66 times the inverter’s rated output power. In-rush currents must stay within limits to avoid shutdown, and the system is not recommended for equipment requiring uninterrupted power (e.g., medical devices). It performs well for short outages but is less suitable for full or prolonged off-grid use or heavy inductive loads compared to a Deye-based system with strong generator support.
  • Considerations: Mid-tier positioning means value depends heavily on your specific usage and load types (especially air cons and pumps). For a tailored recommendation, share your bills and plans — call 07 4191 6815.

  • GoodWe ESA (40kWh) ≈ $24,000+
  • Deye AI-W (30kWh) ≈ $21,000+
  • Anker Solix (30kWh) ≈ $23,000-+

+ OffGrid/Remote Costs/Travel and other install extras

Final Recommendation

  • Best Dollar per kWh for Off-Grid/Rural: The Deye + RUIXU combo remains extremely strong for massive, long-life storage, especially where generator backup and heavy cycling are needed.
  • Best Technology/Features: Sigenergy for premium, EV-ready smart experience.
  • Best Peace of Mind for Grid Homes: GoodWe ESA for proven reliability and robust whole-home backup on stable grids (but keep the motor-load limits in mind for both GoodWe and Dyness if you have heavy inductive appliances).

Action Plan (Post-May 1):
Focus on right-sizing the battery to your actual usage and load types (especially motor loads like air conditioners and pumps) rather than chasing maximum capacity. Consider your location — urban/regional homes usually benefit from simpler hybrids, while rural or off-grid properties may justify the Deye + RUIXU approach.

For a personalised comparison in the Brisbane/Queensland area (including current pricing, payback estimates, and off-grid suitability), call us on 07 4191 6815 and share your recent bills, solar setup, major appliances, and property type.

Prices and incentives can fluctuate. Always verify with your installer and the Clean Energy Regulator’s STC calculator for the latest figures.

This version keeps everything balanced and professional while clearly highlighting the practical limitations of both GoodWe and Dyness for off-grid scenarios (contrasted against Deye). Let me know if you’d like any wording softened, expanded, or further adjustments!

Why Natron Energy Collapsed

What happens when mass manufacturing and scale disrupts new and sometimes better technology for niche applications

Inside the $1.4B Battery Dream That Died Overnight

Just one year after announcing a $1.4 billion sodium-ion battery gigafactory that promised 1,000 high-wage jobs in rural North Carolina, Natron Energy is gone.

On September 4, 2025, the 13-year-old California startup shut down all operations, laid off its entire workforce of ~95 employees, and abandoned plans for what was to be one of the largest sodium baed clean-energy investments in the USA

The news hit like a shockwave — not just for the workers in Michigan and California, but for state officials who had already approved $56.3 million in incentives (none of which were paid).

So what went wrong?

In this deep-dive investigation, we uncover the real reasons behind Natron’s collapse — from frozen investor payments and policy shifts to manufacturing economics and a fatal mismatch between innovation and market timing.

The Final Days: A Desperate Search for Cash

According to internal documents and interviews, Natron’s board made the final call on August 27, 2025: fundraising efforts had failed.

“Natron’s efforts to raise sufficient new funding were unsuccessful, having failed to result in sufficient funding proceeds to cover the required additional working capital and operational expenses.”
— Elizabeth Shober, Head of Team & Talent, in letter to Michigan labor officials

The company had been in survival mode for months:

  • Existing investors — including Chevron, United Airlines Ventures, and Khosla Ventures — froze scheduled payments starting in June 2025.
  • A Series B round was pitched but never closed.
  • Debt financing talks collapsed.
  • Even a last-ditch asset sale (via California advisory firm Sherwood Partners) came too late.

By late August, Natron had only $25 million USD in booked orders — mostly for data center backup power — but couldn’t fulfill them. Certification delays (UL 1973) and the looming 60-day WARN Act layoff notice created a death spiral:
no delivery → no revenue → no investor confidence → no lifeline.

CEO Colin Wessells stepped down in December 2024 — citing the “all-consuming” burden of fundraising. His departure was an early warning sign.

The Cost Conundrum: BOM vs. Reality

Natron’s sodium-ion batteries were built on a compelling promise: cheaper, safer, more sustainable than lithium-ion.

Using Prussian blue electrodes and abundant materials like sodium, aluminum, iron, and manganese, the company avoided lithium, cobalt, and nickel entirely. No rare earths. No geopolitical risk.

ComponentNatron (Sodium-Ion)Lithium-Ion (LFP)
CathodePrussian blue (Fe, Mn, Na)Lithium iron phosphate
AnodeHard carbonGraphite
ElectrolyteSodium salt in organic solventLithium salt
Projected BOM Cost (2030)$10/kWh (grossly exaggerated)$40–60/kWh

But here’s the catch: low energy density (~50 Wh/L vs. 300 Wh/L for Li-ion) meant Natron’s batteries were only viable for power-dense applications like grid or data centre stabilization and or possibly fast-charging stations — not EVs or consumer devices. The reality was, they were heavy, and huge. And over time, the price of Lithium based batteries fell so quickly, that most technology has been put out of business.

China dominates battery manufacturing, overnight in december 2024, CATL announced a 50% price drop for LFP batteries at the cell level. From around $100 per kWh to $50 per kWh. This price is wholesale, without any retail margins, so its not the true cost, but it gives you an idea, of the power they can weild, this also affected many other chinese companies, such as Gotion, but this decision also completely wiped out all the planned factories across the globe, some in the USA, and some in Australia who had been budgeting for $100 a kWh, they now had no future.

China is not messing around, this is a fight that without mega Billions of dollars, supply chains and the highest level of automation, the competiting countries have no chance of getting off the ground.

And while long-term BOM costs looked promising, scaling manufacturing was brutally expensive:

  • Retrofitting the Michigan plant cost $40 million.
  • The North Carolina gigafactory was budgeted at $1.4 billion — 40x the Michigan site’s capacity.
  • Upfront system costs were higher than Li-ion initially, with savings only over 50,000+ cycles.

Even with $35/kWh IRA tax credits, the math didn’t work without massive volume — and volume required capital Natron no longer had.

Market Timing: The Lithium Price Crash

In 2022, lithium carbonate hit $80,000/ton. Sodium-ion looked like the future.

By 2025? Under $10,000/ton. A 70%+ collapse.

Suddenly, lithium iron phosphate (LFP) batteries — already dominant in China — became cheaper than ever. Data centers and utilities asked: Why switch to an unproven chemistry?

Natron’s niche advantage evaporated.

The Full Breakdown: Why Natron Failed

What’s Next for Sodium-Ion?

Natron’s collapse is not the end of sodium-ion technology.

Experts like those at Mana Battery call it “very specific to Natron” — citing execution missteps, niche focus, and bad timing. Others, like Bedrock Materials and Peak Energy, are still advancing sodium-ion with smaller, grid-focused strategies.

China already has over 10 GWh of sodium-ion capacity online. The chemistry works. The market exists.

But Natron’s story is a sobering reminder: in clean energy, innovation alone isn’t enough. You need capital, timing, policy, and customers — all aligned.

North Carolina’s Kingsboro megasite is back on the market.
State officials call it “one of the top megasites in the country.”
This was its second major flop in seven years.

Differences in Internal Resistance between LFP manufacturers and cell models

Overview of LFP Prismatic 314Ah Cells

Lithium Iron Phosphate (LiFePO4 or LFP) prismatic cells in the ~314Ah capacity range are popular for energy storage systems (ESS), electric vehicles (EVs), and solar applications due to their safety, long cycle life (often 4,000–8,000+ cycles), and stable voltage plateau around 3.2V. These cells share similar dimensions (typically ~174mm x 72mm x 207mm) and chemistry but differ in design optimizations, leading to variations in performance metrics like internal resistance (IR).

Observed IR values (EVE MB31 ~0.18 mΩ, LF304 ~0.15 mΩ, REPT ~0.23 mΩ) align closely with manufacturer specifications and real-world testing. Note that IR is typically measured as AC impedance at 1 kHz (per industry standards) and can vary ±0.05 mΩ due to factors like temperature, state of charge (SOC ~30–50% for fresh cells), and measurement tools. Lower IR generally means better efficiency (less heat, higher discharge rates), but all these values are low for 314Ah LFP cells, indicating high-quality Grade A (or HSEV/EV-grade) products.

Confirmed Internal Resistance Specs

Based on official datasheets and verified seller data:

Manufacturer/ModelNominal CapacityInitial IR (AC, 1 kHz)Typical Real-World RangeCycle Life (0.5C/0.5C)Key Notes
EVE MB31314Ah≤0.18 mΩ (±0.05 mΩ)0.16–0.23 mΩ≥8,000 cyclesNewer high-density evolution of EVE’s 304Ah line; optimized for ESS with low heat generation. Tested capacities often exceed 330Ah.
EVE LF304304Ah≤0.15 mΩ (±0.05 mΩ)0.14–0.20 mΩ≥4,000 cyclesOlder high-power model; slightly lower capacity but prioritized for EV/high-discharge apps. IR can appear lower due to thicker electrode coatings.
REPT (CB75/CB71)314Ah≤0.23 mΩ (±0.05 mΩ)0.20–0.25 mΩ≥8,000 cyclesFocuses on “Wending” tech for space efficiency; higher IR but excellent thermal stability and 95%+ efficiency at 0.5P discharge.

These values come from EVE and REPT official datasheets, with real-world ranges from independent tests (e.g., DIY solar forums and battery resellers). The LF304’s lower IR reflects its design for power delivery, while REPT’s slightly higher value trades off for enhanced safety and longevity in stationary storage.

Why Variations in Internal Resistance Between Manufacturers?

Internal resistance in LFP cells arises from ohmic (electrolyte/connector) and polarization (electrode/ion diffusion) components. While all LFP cells use the same base chemistry (LiFePO4 cathode, graphite anode, liquid electrolyte), manufacturers like EVE and REPT optimize differently, leading to IR differences of 0.03–0.08 mΩ. Here’s a breakdown of key factors:

  1. Electrode Design and Material Choices:
    • Particle Size and Coating Thickness: Finer cathode particles or thinner coatings (e.g., EVE LF304’s high-power focus) reduce ion diffusion paths, lowering polarization resistance (~0.10–0.15 mΩ contribution). REPT’s “double-high” solid-liquid interface uses coarser particles for stability, slightly raising IR but improving cycle life.
    • Tab Configuration: More/wider current collectors (tabs) shorten electron paths. EVE MB31 uses stacked/wound hybrids with more tabs, achieving ~0.18 mΩ. REPT’s top-to-bottom “Wending” tech maximizes space but can add ~0.05 mΩ due to longer internal paths.
  2. Manufacturing Processes and Quality Control:
    • Assembly Uniformity: Variations in electrode alignment, electrolyte filling, or welding introduce inconsistencies. EVE’s highly automated lines yield tighter IR tolerances (±0.05 mΩ), while REPT emphasizes safety testing, which may allow a broader range.
    • Grade and Sorting: All are Grade A, but “HSEV” (high-safety EV) variants (common for these) are sorted for low IR. Subtle batch differences (e.g., electrolyte additives for thermal runaway prevention) can shift IR by 10–20%.
  3. Optimization Trade-Offs for Application:
    • Power vs. Energy Focus: LF304 (EVE) targets EVs with high C-rates (up to 1C continuous), needing ultra-low IR for minimal voltage sag. MB31 balances ESS longevity. REPT prioritizes stationary storage, where higher IR is acceptable for better abuse tolerance (e.g., overcharge resistance up to 270°C).
    • Energy Density Enhancements: Higher-density cells (e.g., MB31’s 173 Wh/kg) pack more active material, potentially increasing resistance slightly if not offset by innovations like REPT’s 7%+ space utilization boost.
  4. Measurement and Environmental Factors:
    • Test Conditions: Specs use fresh cells at 25°C and ~30% SOC. Real measurements (e.g., your 0.23 mΩ for REPT) may vary with tools—use a 1 kHz AC meter for accuracy. Temperature swings (±10°C) can change IR by 20%.
    • Aging and Degradation: IR rises ~50–150% over life (faster in LFP than NMC), but your values suggest new cells.

Overall, these variations (20–50% relative difference) are normal and don’t indicate defects— they’re engineered for specific strengths. For ESS, REPT’s higher IR means ~2–5% more heat at 0.5C but superior safety. EVE’s lower IR suits high-draw apps like inverters.

Recommendations

  • Matching Cells: For packs, match IR within 0.05 mΩ to avoid imbalances (use a calibrated meter like YR1035+).
  • Testing: Discharge at 0.2C to verify capacity (>310Ah expected) and monitor IR over cycles.
  • Sources: Download full datasheets from EVE/REPT sites or resellers like GobelPower for curves. For comparisons, check ECO Teardown’s aggregated specs.

Conclusion

Not all LFP cells are made equally, they are optimised for slightly different applications. We choose the best balance and allow you to make a decision based on these factors.

In most cases, using EVE or REPT for the high majority of cases, will make little difference, but for small 12v inverter applications attached to a 3000w Inverter, EVE LF304 might be most suitable if you are looking for high power continuous applications, Either way its likely you will see thousands of cycles .

In reality, most people size their battery appropriately if budget allows, we would recommend 2 x 12v 314ah batteries for those looking to pull 3000w regularly, this might be for cooking, microwaves or even small Air conditioning systems.

  • Their product lines include traction batteries (for EV, commercial vehicles, construction machinery etc.), energy storage systems (ESS), and energy management systems.
  • Their R&D spans multiple chemistries and product types: lithium-ion, solid-state, sodium-ion, LMFP (Lithium Manganese Iron Phosphate), cylindrical cells etc. en.cornexbattery.com

Manufacturing, Scale & Technology

Factory / Plants & Capacity

  • They have three main bases in Xiaogan, Wuhan and Yichang.
  • Their effective production capacity (as of recent reporting) exceeds 100 GWh.
  • They have mass production capabilities for advanced battery cells: for example, the 472Ah energy storage cell started mass production in Xiaogan.

Technology & Manufacturing Efficiency

  • Their “smart factory” / intelligent manufacturing approach aims to use high automation (automation rate >98%), digitalization (tracking from materials to sale), and AI, big data, cloud, VR/AR for process monitoring
  • They claim “less than 5,000 m² plant area per GWh” of capacity, which is a measure of land/space efficiency.
  • Their R&D output is considerable: thousands of patents filed globally, dozens of products, many certifications.

Recent Breakthroughs & Products

  • 688Ah ES (Energy Storage) battery cell: A super-large capacity cell, with volumetric energy density exceeding 430 Wh/L, gravimetric nearing 200 Wh/kg. Over 10,000 cycles, safety features like double-sided ceramic separators etc.
  • Their containerized-storage systems (e.g. “M5” 5MWh 20-foot container) for large energy storage applications. en.cornexbattery.com

Available Products

Currently the 100ah, 200ah and 314ah are the products we will be most interested in. Specifically we like the 314ah cell. It offers a EVE or CATL quality product, with high cycle life and great internal resisitance. This cell offers us a price advantage of about $200 per battery, Which may not sound like much, but at the same quality, its a no brainer, if competition in the area is weak, then EVE may not choose to be competitive which puts us all at a disadvantage in the future. We have found that EVE is now commanding a premium price, and the value is not true.

You can think of this like Duracell vs Energizer vs eveready in AA batteries if they all make a 100% equivalent battery product, and they last for the same or better, then its no longer an intelligent choice to preference a brand over the quality and value. Competition is important and so we will be looking for your support while we take Cornex product and use it regularly to ensure competition in the industry.

314 Ah Cell (Conergy π 314Ah / PF173-314A)

This is one of Cornex’s flagship cells for energy storage (ESS) applications.

Key specifications:

ParameterTypical / Market Spec
Nominal Voltage~ 3.2 V
Capacity~ 314 Ah
Internal Resistance≈ 0.17-0.19 mΩ
Cycle Life~ 8000 cycles (to ~80-65 % capacity, depending on spec)
Charge / Discharge RatesStandard 1C / some pulse up to ~2C (short bursts) in some specs; continuous discharge is modest.
Temperature PerformanceDischarge: -20 °C to ~ 55 °C; Charge: 0-55 °C
Physical Size / Weight~5.5-6 kg; dimensions ~ 174.4 × 71.5 × 207.2 mm

What makes the 314 Ah special / strengths:

  • High capacity per cell → fewer cells needed for a given ESS capacity, savings in BMS, interconnects, weight per kWh.
  • Low internal resistance → less voltage drop under load, better efficiency, less heat.
  • Good cycle life (8,000+ cycles) helps with lifespan and lower cost per cycle.

Strategic Moves & Competitive Position

  • Cornex is executing a dual strategy: ESS + EV batteries. So not just large stationary storage, but also vehicle traction batteries.
  • They are moving into or expanding in overseas markets: They have technical/service networks in ~15 countries/regions.
  • They have secured major EV battery contracts, e.g. over 30 GWh nomination from Dongfeng Liuzhou Motor.
  • They are pushing safety, green-manufacturing credentials: designated a “National-Level Green Factory” by China’s MIIT.

Price & Value Edge / What Gives Them Advantage

From the data, here are the levers that seem to give CORNEX an edge in price / cost versus value:

  1. Scale: With >100 GWh capacity, large plants, mass production of advanced cells, they get larger economies of scale. Fixed costs get spread over more output.
  2. Efficiency / Automation / Digitalization: Very high automation, smart factory technologies reduce labor cost, defect rates, improve yield. Tracking materials → less waste, better process control.
  3. Technological Innovation: Their newer products (472Ah, 688Ah, etc.) boost energy density, cycle life, and capacity per cell & per container, which helps reduce $/kWh over life. Similarly features like “cathode pre-lithium,” “high-temperature durability” help add value.
  4. Space and Land Efficiency: Claiming less plant area per GWh is a sign of cost savings in land, infrastructure.
  5. Green credentials / regulatory compliance: Being certified “green factory,” meeting often tight safety and environmental standards helps them in both domestic regulation and overseas tenders (where safety / environmental compliance can be part of the cost). Adds value to customers.
  6. Integrated supply / localization: Their R&D across multiple chemistries, in multiple product types, their strong IP position, and a broad product portfolio means they can serve many segments, adapt to demand, potentially reduce supply chain risk.
  7. Speed to market & continuous iteration: Example: They take existing 314Ah lines, use “technology reuse + shared capacity” to faster develop 472Ah. So leveraging existing manufacturing investment rather than building totally new lines for each innovation.

Possible Weaknesses or Challenges (for balance)

To round out the picture, also useful to think of what could limit them:

  • Battery raw materials (lithium, cobalt, etc.) are globally volatile; cost increases can eat margin even for large players.
  • Overseas competition is intensifying (CATL, BYD, other Chinese battery firms, as well as international players). So staying ahead in R&D, safety, and regulations is critical.
  • For exports, ensuring that certifications (UL, IEC, safety, environmental) are all in place can slow things or add cost.
  • Logistics and localization costs (shipping heavy battery systems, or assembling in overseas markets) can erode advantages.
  • Long-term safety and degradation are always concerns; promises like “15,000 cycles at 35°C” need long-term tests and customer trust.

Who is Deye?

Who is Deye? And what makes them special?

Deye is a leading manufacturer of high quality renewable energy solutions, they really have taken the market by storm in the last 5 years in Australia. The products we absolutely love here in at LiFePO4 Australia is the range of SUN Hybrid Inverters. Starting at just 5000W single phase 48v LV right up to the 16kW single phase LV model which really is groundbreaking.

Deye also makes products for SunSynk and Sol-Ark, along with NoArk who has the products in Australia.

Origins, corporate structure & listing

Deye grew out of Ningbo Deye Technology, a diversified appliance and climate-tech manufacturer founded in 1990 in Ningbo, Zhejiang. In 2007 it spun up Ningbo Deye Inverter Technology to focus on PV power electronics and later energy storage (ESS).

What Deye builds: the product families

1) SUN-series hybrid inverters (residential & C&I)

  • Single-phase 48 V (LV): e.g., SUN-5-16K-SG0(x)LP1-AU variants
  • Three-phase 48 V (LV): SUN-5/6/8/10/12K-SG04LP3-AU for Australia
  • Three-phase high-voltage (HV): Various models from 5K up to 100K

Single Phase Hybrid LV (48v Battery)

Big Residential Hybrid LV Inverters

Three Phase Hybrid LV (48v Battery)

Batteries

  • Rack – IEC listed (good when no rebates are applicable
  • Stack – CEC approved (rebates)
  • Wall Mount CEC approved (rebates)

Recommended products

Deye is a vertically-integrated Chinese manufacturer that evolved from climate appliances into a full-stack PV-plus-storage supplier. The SUN-series hybrids earned a following by combining feature-dense controls (parallel/off-grid/AC-couple/genset support) with 48 V battery friendliness and region-specific compliance. For Australian projects in 2025, the critical checks are: current AS/NZS 4777.2 Amd 2 compliance, presence on CEC/CER-maintained approved lists, and battery-BMS compatibility per the latest Deye tables. That diligence preserves rebate eligibility, simplifies commissioning, and ensures the hardware behaves exactly as your design expects.
