The DC OUT of PV charges the battery for energy storage with Sunfine SMB, when the produce energy of PV is in abundance, the DC OUT of PV will invert to stable AC supply to load with Sunfine SMB, and once the produce energy of PV is short of supplies and also the supply of national grid is abnormal, the DC OUT of battery will output stable AC supply to load.
