Home energy storage system (ESS) involves storing electricity locally using household energy storage equipment for later use. ESS comprises energy storage batteries, inverters, and other components. We utilize brand-new A-grade LiFePo4 batteries equipped with an intelligent battery management system for charging and discharging cycles. The inverter converts DC energy to AC energy to meet household electricity requirements. Typically, this product is installed in combination with a PV system to provide green electricity to households, reduce energy consumption, and minimize negative impacts on the environment. It is widely used in remote areas or areas with unstable power supply to offer reliable, stable, and cost-effective energy supply.
