220VAC 1.5Kw 7A Generally Type For Single Phase Motor Solar Pump Inverter
ZK SG320-1K5GB-2S Solar Pump Inverter description
Solar pump inverter, also named solar variable frequency drive (solar pump VFD)suitable for solar photovoltaic water pump systems.
The direct current generated by the solar modules is input to the photovoltaic water pump controller, converted into alternating current, and directly drives various water pumps.
Solar Pump Inverter Features

SG320 series solar pump inverter compatible with dual supply mode
The solar pump inverter operates in dual supply mode either with a three phase input supply from the grid or with DC input supply from PV cells. A four-pole changeover switch enables switching between the two supply modes. At a given time only one supply (PV cell or grid) will be connected to the drive.
