3 Phase Inverter Zundrive 0.75kw - 250kw Solar Pump Inverter ForPMSM And IM Motor
Water Pumping Inverter Introduction:
Solar water pumping solution is a fully automatic system designed to provide water at affordable cost for people with limited or no access to electricity. It uses the most advanced SG320 Solar variable speed drive to regulate the speed of a 1/3-phase AC motor depending upon the solar energy available from the solar panel.
The system is composed of a PV generator, a pump and a solar pump inverter. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as storage battery in the system. The system is prepared to be combined with a elevated water storage, e.g. water tower or an uphill tank installation.
