12.8V 300AH

12.8V 300AH

This product is mainly combined with inverter, photovoltaic (PV) and related accessories to build residential energy storage system. The system is used to store the direct current (DC) generated by photovoltaic (PV) in the connected battery, and convert the direct current (DC) generated by the connected battery into alternating current (AC) and provide it to the home grid.

(Note: The actual Residential ESS may also include electrical equipment such as distribution boxes and metering meters)
12v lithium battery is a lithium-ion battery that can store electrical energy and outputs DC current. 12v lithium battery only maintains electrical connection with the inverter. The electrical energy generated by the PV is converted by the inverter Dc to DC and stored in the connected 12v lithium battery. When 12v lithium battery is needed, 12v lithium battery’s electrical energy is converted by the inverter DC to AC and transmitted to the home grid to provide power for household appliances.
