Frequently Asked Questions

How many essential appliances can this 5.12kWh battery power during an outage?

A 5.12kWh battery could power a 500W refrigerator for about 10 hours, plus LED lights and Wi-Fi router for several hours more. An energy audit is recommended for precise planning.

Is a special battery charger required?

Designed to be charged directly by compatible solar hybrid or off-grid inverters configured for LiFePO4 chemistry with 57.6V absorption setting.

Can this battery be installed outdoors?

While IP55 rated offers good protection, installation in dry, well-ventilated, temperature-controlled indoor spaces is strongly recommended.

How do I check compatibility with my existing solar inverter?

Compatibility depends on inverter's supported battery voltage and communication protocol. The YF51100LFP-FS uses standard 51.2V voltage and RS485/CAN communication.
