Solar Energy Storage Charger Integrated Solution

PV BESS charging station system Combining the photovoltaic garage system, battery energy storage system (BESS) and electric vehicle charging equipment, the monitoring system is integrated in one. Make full use of public space, environmental protection power generation. The photovoltaic power generation system first provides power for loads such as charging piles, and stores the excess electric energy in the commercial solar power storage batteries to supplement when the solar energy system is insufficient. Through the coordination of solar energy and energy storage systems, we can minimize the amount of electricity generated from the grid and reduce electricity bills.
