The 51.2V 314Ah LiFePO4 battery is a mainstream preferred device for household solar energy storage, with a rated energy storage of about 16kWh, compatible with most household photovoltaic systems. Adopting safe and stable lithium iron phosphate material, it is high temperature resistant and not easy to thermal runaway, suitable for long-term household static energy storage. It efficiently stores photovoltaic power on sunny days and avoids energy waste. Compatible with household inverters for stable power output, it has higher energy density and lower loss than lead-acid batteries, maximizing solar energy utilization and building an economical, eco-friendly and stable distributed energy storage system for families.
