The GoodWe ES series bi-directional hybrid energy storage inverter is suitable for both on-grid and off-grid PV systems. It can also control the flow of energy intelligently. During the day, the PV plant generates electricity which can be provided to the loads, fed into the grid or charge the battery. The electricity stored can be released when the loads require it during the night. Additionally, the power grid can also charge the storage devices via the inverter.
