Lithium inverter batteries for Nigeria
51.2 V LiFePO4 batteries from 5 to 20 kWh for the 48 V inverters that homes, shops and offices across Nigeria run every day. Matched to the inverter’s KVA, shipped by sea to Lagos.
What we keep in mind for Nigerian installs
Sized by KVA
We match the battery to the inverter’s power, not only its voltage, so the battery is not working at its current limit every evening.
Replacing tubular banks
In a 48 V system, one 51.2 V lithium battery takes the place of four 12 V batteries in series.
Grid or generator charging
The inverter charges the battery from whichever AC source is on. Keep its charge current within the battery’s recommended 50–100 A.

| Inverter | Battery current at full load | What we suggest |
|---|---|---|
| 3.5 KVA (about 3 kW) | 62 A | One 10 kWh unit (100 A recommended), or two 5 kWh units in parallel |
| 5 KVA (4–5 kW) | 82–103 A | One 10, 15 or 16 kWh unit runs at about its recommended 100 A; add a second unit for long full-power use |
| 7.5 KVA (6–7.5 kW) | 123–154 A | One 16 or 20 kWh unit (200 A max), or two 10 kWh units if it runs near full power for hours |
| 10 KVA (8–10 kW) | 164–206 A | Two 10–20 kWh units in parallel, so each stays near its recommended 100 A |
Rule of thumb: about 20 A of battery current per kW of inverter output at 51.2 V, allowing for about 95% inverter efficiency. 5 kWh units are rated 50–70 A recommended and 100 A maximum; our 10–20 kWh units 100 A recommended and 200 A maximum. Check the kW rating on the inverter label: a KVA figure is often a little higher than the real output. Runtime is a separate question; see the capacity pages.

- SONCAP
- Nigeria’s National Single Window lists a SONCAP certificate as mandatory for electrical goods (HS 8501–8548, which includes batteries). The importer arranges the Product Certificate and SONCAP Certificate through an accredited body such as SGS, Bureau Veritas or Intertek. We send the datasheets and the test reports we hold.
- Shipping
- LiFePO4 batteries go by sea as Class 9 dangerous goods, with the UN38.3 test summary and MSDS, to Lagos (Apapa or Tin Can Island).
- Your documents
- Commercial invoice, packing list, datasheets and the CE, UN38.3 and MSDS documents listed for each model.
Import rules change. Your clearing agent has the final word on what each shipment needs.
What size battery do I need for a 10KVA 48V inverter?
At full load a 10 KVA (8–10 kW) inverter draws about 165–205 A from a 51.2 V battery. One 10–20 kWh unit can only supply that near its 200 A maximum, so we suggest two units in parallel: 2 × 10 kWh, or 2 × 16 kWh for longer runtime.
Can a lithium battery replace my tubular batteries?
Yes. In a 48 V system one 51.2 V lithium battery replaces a bank of four 12 V batteries in series. Set the inverter’s battery type to lithium, or connect the CAN / RS485 cable so the inverter reads the battery directly. The charge voltage must not go above 58.4 V.
How long will a 10 kWh battery last when there is no light?
About 8 hours at an average load of 1 kW, or about 27 hours at 300 W for a fridge, lights, Wi-Fi and TV, using 80% of the stored energy. The 10 kWh page has the full table.
Will it work with my inverter?
Our 51.2 V batteries talk to inverters over CAN and RS485, and most models also have RS232. Send us the inverter brand and model and we check the communication protocol before you order.
Do you handle SONCAP?
The importer applies for SONCAP through an accredited inspection body. We send the datasheets and the test reports we hold (CE, UN38.3, MSDS) that the inspection body asks for.
