Low Voltage Battery
Compare 51.2V LiFePO4 batteries for home solar storage and backup power, from 5.12kWh to 15.36kWh. Choose by inverter compatibility, output power, and capacity.
What Is a Low Voltage Battery?
For the models shown here, a low voltage LiFePO4 battery has 51.2V nominal voltage and belongs to the 48V-class storage category. Match inverter voltage range, BMS protocol, and discharge current before buying. Even at 51.2V, a low voltage lithium battery is not compatible with every 48V inverter. This page focuses on 51.2V low-voltage battery systems. For larger commercial storage projects, see our high-voltage battery solutions.

Inverter & Solar Compatibility
For a low voltage solar battery, the inverter must support the operating voltage, battery communication protocol, and charge/discharge current limits. Matching CAN / RS485 connectors alone does not establish BMS compatibility.
| Check | Confirmed Detail |
|---|---|
| Nominal Voltage | 51.2V for all three models |
| 5kWh Voltage Range | 44.8–57.6V DC |
| 10kWh Voltage Range | 48–57.6V DC |
| 5kWh Communication | CAN / RS485 / RS232 |
| 10kWh & 15kWh Communication | CAN / RS485 |
| Backup Output | Inverter must have backup output capability |
Battery Expansion
Expanded systems also require matching inverter current settings and BMS communication.
| Battery | Expansion |
|---|---|
| 5kWh | Up to 10 units in parallel |
| 10kWh | Up to 6 units in parallel |
| 15kWh | Parallel connection supported |
Installation & Protection

FAQ
Can a 51.2V battery work with my 48V inverter?
Only when the inverter's battery voltage range, charging settings, current limits, and BMS protocol match the product.
Is 10kWh enough for home backup?
Check the loads that need power and how long they must run. Nominal capacity alone does not establish backup time.
Can the 5kWh model continuously power 5kW loads?
No. This 5.12kWh model has a 3.84kW maximum battery output.
Can I add more batteries later?
Yes. The 5kWh model supports up to 10 parallel units, and the 10kWh model supports up to 6. Expansion also requires compatible inverter and BMS settings.
How do I get a low voltage battery price?
Pricing is based on battery model, quantity, inverter requirements, and shipping destination. Inverter and installation charges must be identified separately if not included.
