Solar Pump Inverter PV300 22KW
PV300 Series Solar Pump Inverter
Solar pumping inverter is used to control and regulate the operation of solar water pump system (PV pumping system). It can convert the DC from the solar array into AC to drive the water pump.
Half of the energy produced around the world is used to operate pumps. Compared to diesel generator pumps, our solar pumping inverter are environmentally friendly, with a long lifetime and low maintenance costs. It is independent from the grid and produces no pollution or noise. Typical applications are irrigation, community water supply, fish farming and agriculture.
Product Features
◇ The solar pumping inverter is suitable for all kinds of pumps, including single phase 220V pump.
◇ With water level detection function, automatically regulate the pump flow to prevent dry running, full water level, etc.
◇ The solar pumping inverter is easy installation and effortless maintenance.
◇ Standard RS485 interface, support to remote monitor the system with the software on PC.
