Project Description

GoodWe developed GW5048D-ES / GW3648D-ES, a bi-directional energy-storage inverter which is applicable for both on-grid and off-grid PV systems and can control the flow of energy hybrid with its working situation able to be switched automatically or manually. During the day time, the PV plant generates electricity which can be provided to the loads, fed into the grids or charged the battery. The power stored can be released when the loads require it during the night. Additionally, power grid can also charge the storage devices via the inverter.
