Low Voltage (LV) 51.2V LiFePO4 Batteries

The Smarter Energy Choice for Australian Households

Low Voltage (LV) 51.2V LiFePO4 batteries are transforming the way Australian homes generate, store, and use energy. Whether you’re aiming for energy independence with an off-grid system or enhancing your on-grid solar setup, these batteries provide unparalleled reliability, safety, and efficiency.

Discover why they’re the perfect fit for your energy needs.

Why Choose LV 51.2V LiFePO4 Batteries?

1. Safety and Reliability
   • Stable Chemistry: LiFePO4 batteries are among the safest lithium chemistries, with a proven track record for thermal and chemical stability.
   • Long Lifespan: Designed for durability, these batteries can deliver up to 10,000+ cycles, ensuring 10–15 years of reliable performance.
   • LV (low voltage) For most residential, off-grid, or backup power systems, 51.2V LiFePO4 batteries offer a compelling combination of safety, simplicity, flexibility, and cost-efficiency.
2. Optimal Performance for Solar Applications
   • High Efficiency: Maximize your energy usage with minimal losses during charge and discharge.
   • Consistent Output: Delivers stable voltage throughout its charge cycle, making it ideal for sensitive electronics and high-power devices.
3. Cost-Effective Energy Storage
   • Lower total cost of ownership compared to alternatives
   • Reduced reliance on grid power saves you money on electricity bills.
4. Environmentally Friendly
   • 95%+ recyclable and free from toxic heavy metals, contributing to a greener planet.

Cost-Effectiveness

1. Lower Upfront Costs:
   • 51.2V LiFePO4 batteries are significantly cheaper per kWh compared to proprietary systems like the Tesla Powerwall.
   • Proprietary systems often include built-in software, branding, and installation costs that drive up the price.
2. No Forced Ecosystem: Proprietary systems like the Powerwall include built in inverters and often lock you into a particular ecosystem, increasing overall costs.With 51.2V batteries, you can choose compatible inverters, chargers, and monitoring systems to match your budget and needs.

Perfect Pairing with DEYE and Victron Inverters

When paired with advanced inverters like the DEYE Hybrid LV SUN-5K-SG04LP1-AU or a Victron AC Coupled System, LV 51.2V batteries integrate seamlessly into your home energy system.

• DEYE Hybrid Inverters: Provide robust support for off-grid systems or grid-tied setups with backup functionality.
• Victron AC Coupled Systems: Expand your existing solar system without replacing your existing PV inverter, offering flexibility and reduced cost.
• Understanding AC Coupling: AC coupling refers to the configuration where both the battery inverter (e.g., MultiPlus-II) and the grid-tied solar inverter are connected on the AC side of the system. In this setup, the solar inverter supplies AC power, which can be used directly by AC loads or converted by the MultiPlus-II to charge the batteries.
• 2. Frequency Shifting for Power Regulation: The MultiPlus-II utilizes frequency shifting to manage the output of the grid-tied solar inverter, especially during off-grid operation or when battery charging is complete. By slightly increasing the AC frequency, the MultiPlus-II signals the solar inverter to reduce its output, thereby preventing battery overcharging and potential system overloads.
• Victron Energy
• 3. Adhering to the Factor 1.0 Rule: It’s crucial to ensure that the maximum power output of the grid-tied solar inverter does not exceed the VA rating of the MultiPlus-II. This “Factor 1.0” rule helps prevent scenarios where sudden load drops could lead to battery overcharging or AC voltage spikes. For instance, a 3,000 VA MultiPlus-II should be paired with a solar inverter whose output does not exceed 3,000 W.
• Victron Energy
• 4. Compatibility with Frequency Shifting: Not all solar inverters support frequency shifting. It’s essential to verify that your existing solar inverter can respond appropriately to frequency changes initiated by the MultiPlus-II. Some inverters have settings or modes (often referred to as “island mode” or “micro-grid mode”) that enable this functionality. Consult your solar inverter’s documentation or manufacturer to confirm compatibility.

These pairings deliver an adaptable energy solution tailored to Australian households, whether you’re starting fresh or enhancing an existing solar system.

On-Grid or Off-Grid: Versatility for Every Home

Off-Grid Applications:

• Reliable Power Supply: Ideal for rural properties or areas with limited grid access, providing consistent electricity.
• Energy Storage: Store excess solar energy for use during nighttime or cloudy days, ensuring uninterrupted power availability.
• Petrol or Diesel Generators can offer a backup in the rare weather events such as long periods of overcast or cloudy weather.

On-Grid Solutions:

• Cost Reduction: Lower electricity bills by maximizing solar self-consumption, reducing reliance on grid electricity.
• Backup Power: Ensure seamless operation during grid outages, keeping your household running smoothly.
• Energy Storage for Peak Times: Store generated solar energy for use during evening peak rate periods, optimizing energy usage and savings.

Virtual Power Plants (VPPs):

Participating in a VPP allows you to leverage your battery storage to generate income by exporting stored energy to the grid during high-demand periods.

Amber Electric

Some customers have already started to join the Amber/Evergen as mentioned here
(this is a new integration, and therefor now its complete, people can enjoy control over there systems like never before) we think of this as the open source version of Solar and Battery storage. The more people who join, the better it is for all of us together)
