3 Inch solar energy stainless steel screw pump
The solar water pump is a water pump that is both energy saving and environmentally friendly , and it is a combination of a solar deep well pump , a photovoltaic voltage control box and solar panels . The pump body of the solar water pump is a deep well pump , usually a slender cylindrical submersible pump . Remote mountain water supply and mountain water is very convenient , but also through the solar panel to absorb the light as energy , and then converted into electricity , installed in the sunshine bright enough place can be .
Advantage of solar water pump
High efficiency because of PMSM
MPPT function
Longer life than normal AC water pump
Over-load protechion , under-load protection
Lock-rotor protection , thermal proteciton
