2200 Watts 2-Wire Submersible Deep Well Solar / AC Pump  (4THSG75-1500)

This solar pump is rated 2200W(3HP). It is recommended to use 1.5 x 2200W = 3300 Watts solar panel to operate it. However, it works with wide range of power, as low as 1000W for a shallower well or up to maximum power of 3800W of solar power. It is pre-set internally to draw up to 2380W power at the max. Therefore, if you have a much larger solar panel array that the voltage is not exceeds the max of 420Voc, the pump will only work at the preset max power of 2380W and will not be over powered. When using AC 240V power, the pump will work at the preset max power of 2380W(~3HP).

This solar pump can be operated with 6 to 10 same or same rated solar panels in series connection to form an array. Each array should includes the same panels of 280W to 500W (not supplied in this kit). Do not mix different rating panels in the array, the single panel's Voc x numbers of solar panel must not exceed 420V. 

This solar pump is design for high flow but low head. It can pump 75GPM at 80ft head.

Package Includes:

4" 4TMSG1500 motor, 75GPM rated S.S. Solar pump-end, max power consumption up to 2380W (~3HP)

Power Input: Solar DC 120Voc to 400Voc 1000Watt to 3800Watt, or AC 200 to 240V 50/60Hz
