single phase or three phase AC power, simple wiring.
Smart operation, water level detection and operation panel to prevent overflow, dry pumping.
Protect itself in trouble and improve the reliability of whole system.
The bypass- AC source which runs automatically when the sun is Not sufficient or absent.
Tips: Solar pump inverter selection The solar
water pump is not like the pump powered by the conventional AC grid.
Because the electricity generated by the photovoltaic module is the
direct current, it is required to invert the direct current into a
three-phase alternating current for being used by the water pump through
the inverter. Then, the solar pump inverter special for PV water pumps
should be selected with high reliability and high system efficiency. The
capacity of the solar pump inverter must meet the heavy-duty startup of
the selected pump. If it is used the highland area, the capacity
reduction caused by the high altitude must be taken into account, so as
to ensure the long-term and reliable operation of the system. In normal
conditions, the power of the solar pump inverter is required to be one
stage higher than that of the water pump motor.
