Batteries for Inverter — LiFePO4 energy storage for backup and off-grid power
An inverter battery is the core component of any backup or off-grid power system. Modern LiFePO4 batteries deliver stable energy output over 6,000+ cycles, withstand deep discharge down to 80% DoD, and integrate seamlessly with hybrid inverters and solar panels. Our catalog features models from 5 to 25 kWh at 48 V (51.2 V) nominal voltage — suitable for apartments, houses, and small commercial installations.
How to choose a battery for inverter
When selecting a lithium battery, consider your load capacity, desired backup runtime, and inverter compatibility. Below is a comparison of our top-selling models:
| Model | Capacity | Voltage | Cycles | Application |
|---|---|---|---|---|
| Veichi VCLB-5K-D01 | 5.12 kWh | 51.2 V | 6,000 | Apartment, office |
| Felicity LPBA48100-OL | 5.12 kWh | 51.2 V | 6,000+ | Apartment, cottage |
| Felicity LPBA48170 | 8.7 kWh | 51.2 V | 6,000+ | House up to 150 m2 |
| Veichi VCLB-10K-W01 | 10.24 kWh | 51.2 V | 6,000 | House, small business |
| Rosen BAT-51.2V-200AH-WALL | 10.24 kWh | 51.2 V | 6,000+ | House, office |
For an apartment, a 5 kWh battery is sufficient — providing 4 to 6 hours of runtime for a refrigerator, lighting, and router. For a house with electric heating or air conditioning, we recommend 10 kWh or more.
