Introduction
As lithium iron phosphate (LiFePO₄) batteries become the mainstream choice for solar and energy storage systems, inverter compatibility has become a critical factor affecting system performance, safety, and lifespan. Unlike lead-acid batteries, LiFePO₄ batteries have stricter electrical and communication requirements, making inverter selection particularly important.
Voltage Matching Requirements
LiFePO₄ batteries operate within a narrower voltage window. For example, a 48V LiFePO₄ battery typically works between 44V and 58.4V. The inverter must support this voltage range precisely to avoid overcharge or deep discharge, both of which can trigger BMS protection.
Battery Type Recognition
Modern hybrid and off-grid inverters should offer dedicated lithium battery modes. These modes allow the inverter to recognize LiFePO₄ chemistry and apply appropriate charging algorithms instead of default lead-acid settings.
Charging Algorithm Requirements
LiFePO₄ batteries require CC-CV (Constant Current–Constant Voltage) charging without float charging. The inverter must allow users to:
- Disable float charging
- Adjust bulk and absorption voltage
- Set charging current limits
