Description
Sigenergy SigenStor Home Battery System
The goal is simple: help you choose the right Sigenergy battery system without needing to decode inverter jargon, battery naming, gateway requirements, or backup terminology.
The SigenStor system is a modular high-voltage LiFePO4 home battery and hybrid inverter platform. It can be configured as a straightforward solar battery, a blackout backup system, a smart energy management system, or a larger home energy platform with EV charging and generator support.
Important capacity note: the SigenStor BAT 10.0 module name can be confusing. Each BAT 10.0 module has 9.04 kWh total capacity and 8.76 kWh usable capacity. This page uses usable capacity wherever it matters so customers understand the real storage available.
Build Your System in 4 Steps
| Step | What You Choose | Why It Matters |
|---|---|---|
| 1 | SigenStor BAT 10.0 battery modules | Each module adds 8.76 kWh usable storage. More modules increase backup duration and usable evening energy. |
| 2 | SigenStor Energy Controller | This is the hybrid inverter/controller. Choose single-phase or three-phase to suit your property and solar design. |
| 3 | Sigen Gateway | Required when you want safe blackout backup, grid isolation, backup circuits, generator input, or advanced EMS functions. |
| 4 | Optional EV DC charger | Adds high-performance EV charging and future V2X-style energy flexibility where supported and correctly designed. |
Usable Battery Capacity Guide
| BAT 10.0 Modules | Total Capacity | Usable Capacity | Typical Fit |
|---|---|---|---|
| 2 modules | 18.08 kWh | 17.52 kWh usable | Efficient homes, evening load shifting, small backup circuits |
| 3 modules | 27.12 kWh | 26.28 kWh usable | Most medium homes wanting stronger overnight coverage |
| 4 modules | 36.16 kWh | 35.04 kWh usable | Larger homes, heavier evening usage, better backup runtime |
| 5 modules | 45.20 kWh | 43.80 kWh usable | Large homes, three-phase loads, higher self-consumption |
| 6 modules | 54.24 kWh | 52.56 kWh usable | Large residential or small commercial energy storage |
What Is Included
- SigenStor BAT 10.0 modules: modular high-voltage LiFePO4 batteries using 314Ah cells, with integrated LED display and battery-level optimisation.
- SigenStor Energy Controller: the inverter/controller that manages solar, battery, grid and loads.
- Ground mounting kit: included in the bundle configuration for a clean floor-standing installation.
- Optional Sigen Gateway: add this for blackout backup, safe grid isolation, generator support and advanced energy management.
- Optional Sigen EV DC charger: for customers planning an integrated battery + EV energy system.
Why Choose SigenStor?
- All-in-one design: battery, controller, gateway and EV charging can be designed as one coordinated system.
- Expandable storage: start with the capacity you need and expand later as your loads, EV use or backup expectations grow.
- High usable capacity: BAT 10.0 modules provide 8.76 kWh usable energy per module.
- Strong discharge capability: each BAT 10.0 module supports up to 4.6 kW continuous charge/discharge power, with short-duration peak support.
- Outdoor-ready build: IP66-rated system design with natural convection cooling and a clean modular footprint.
- Smarter operation: app monitoring, diagnostics and energy optimisation help the system respond to solar production, tariffs and household usage.
Gateway Explained: Do You Need It?
If you only want normal self-consumption while the grid is running, a Gateway may not be required. If you want backup power during a blackout, the Gateway is normally the part that makes that possible and safe.
| Configuration | Battery Works While Grid Is On | Backup During Blackout | Best For |
|---|---|---|---|
| No Gateway | Yes | No typical backup operation | Customers focused on self-consumption and tariff shifting |
| With Gateway | Yes | Yes, when designed and installed correctly | Customers who want essential-load or whole-home backup |
The correct Gateway depends on your supply type, backup design and installation requirements. Single-phase and three-phase sites need to be assessed differently.
Recommended System Sizing
- Essential backup package: 2 modules plus Gateway for lights, fridge, internet, basic outlets and selected circuits.
- Balanced home package: 3 modules for stronger overnight coverage and better solar self-consumption.
- Large home package: 4 to 6 modules for higher loads, longer backup runtime and three-phase designs.
- EV-ready package: allow extra battery and solar capacity if adding DC EV charging, especially if you want meaningful vehicle charging from stored energy.

Australian Installation Notes
- Pricing is a guide: final installed cost depends on switchboard condition, cable runs, backup design, metering, site access, network requirements and local labour.
- Backup design matters: essential-load backup is usually simpler and cheaper than whole-home backup.
- Regional installs vary: travel, freight, local compliance and additional works can change the final quote.
- Rebate eligibility must be checked: product eligibility, installer requirements, customer eligibility and paperwork can change by program and location.
Best Next Step
If you are unsure which controller, gateway or battery size is right, request a personalised quote. The best SigenStor system is the one sized to your actual usage, solar array, supply type, backup expectations and future EV plans.

Frequently Asked Questions
Is the BAT 10.0 a full 10 kWh usable battery?
No. The BAT 10.0 has 9.04 kWh total capacity and 8.76 kWh usable capacity. This is why the tables above show usable capacity clearly.
Can I add more battery modules later?
Yes, SigenStor is modular. Expansion still needs to be checked against controller limits, installation rules, available space, firmware compatibility and site design.
Do I need the Gateway?
Choose the Gateway if you want blackout backup, generator input, backup circuits or advanced energy management. Without a Gateway, the battery can still work for normal grid-connected self-consumption, but backup operation is generally not provided.
Can this work with EV charging?
Yes, Sigenergy offers integrated EV charging options. The right configuration depends on battery size, solar capacity, phase type and how much energy you want available for the vehicle.
