The DH200F has a multi-functional, all-in-one design that supports flexible expansion, PV access and on-and-off-grid switching. It supports an AC parallel connection of up to 12 units, reaching a capacity of 2.58 MWh. The DC-coupled photovoltaic system enhances solar efficiency and reduces cost. Equipped with STS, it ensures that on-and-off-grid switching time is less than 20 ms, thereby maintaining a stable power supply. It provides peak shaving, grid demand response and backup power services, guaranteeing stable power supply for off-grid use.
