Inverter and BMS Matching

The 150A continuous BMS limit is critical when choosing an inverter. Calculate the inverter’s DC input current at the intended load and allow for conversion losses, battery voltage variation and appliance start-up surge. Do not size the inverter solely from the battery’s 220Ah capacity or 300A short-duration pulse figure.

High-current installations require short, correctly sized cables, secure terminations, isolation and suitable over-current protection. A qualified installer should design permanent or high-power systems.

Charging Compatibility

Use a LiFePO4-compatible solar controller, DC-DC charger or mains charger that can be configured to the battery manufacturer’s voltage and current limits. The listed maximum charge current is 75A and charging is specified from 0°C to 45°C.

Explore MPPT solar controllers, DC-DC chargers and pure sine wave inverters when building the complete system.

Series and Parallel Configuration

The manufacturer lists support for up to four identical batteries in series and two identical batteries in parallel. Only connect batteries when permitted by the current manual, and use matching batteries of the same model, age, capacity and state of charge. Series or parallel banks require appropriate protection and system design.

Frequently Asked Questions

Can this battery support a large inverter?

It may support an appropriately sized inverter, but the intended load must remain within the 150A continuous BMS limit and the complete system’s cable, fuse and surge capabilities.

Can it be charged below 0°C?

The listed charging range begins at 0°C. Do not charge below the manufacturer’s minimum temperature unless current manufacturer documentation specifically permits it.
