750 Watts 2-Wire Submersible Deep Well Solar / AC Pump  (4THSG13-750)

This solar pump is rated 750W(1HP). It is recommended to use 1.5 x 750W = 1125 Watts solar panel to operate it. However, it works with wide range of power, as low as 500W for a shallower well or up to its maximum power of 1350W for a 420 foot deep well safely. It is pre-set internally to draw up to 1350W power at the max. Therefore, if you have a much larger solar panel array that the voltage is not exceeds the max of 380Voc, this pump can be connected to the array directly and it will only work at the preset max power of 1350W and will not be over powered. When using AC 240V power, the pump will work at the preset max power of 1350W. 

This solar pump can be operated with 4 to 6 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 380V. 

This solar pump is design for up to 420 feet head usage. The maximum cut off head is 510ft.

Package includes:

4" nominal 750 Watts (1HP), stainless steel solar pump and motor, max operating power up to 1350W (1.8HP)

Power Input: Solar DC 120Voc to 380Voc 800Watt to 2350Watt, or AC 200 to 240V 50/60Hz
