1500 Watts 2-Wire Submersible Deep Well Solar / AC Pump  (4THSG20-1500)

This solar pump is rated 1500W(2HP). It is recommended to use 1.5 x 1500W = 2250 Watts solar panel to operate it. However, it works with wide range of power, as low as 800W for a shallower well or up to its maximum power of 2450W(3HP) for 500 foot deeper well safely. It is pre-set internally to draw up to 2450W power at the max. Therefore, if you have a much larger solar panel array that the voltage is not exceeds the max of 380Voc, the pump will only work at the preset max power of 2450W and will not be over powered. When using AC 240V power, the pump will work at the preset max power of 2450W(3HP).

This solar pump can be operated with 6 to 8 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 500 feet head. The maximum cut off head is 630ft.

Package Includes:

4" nominal 1500 Watts (2HP), stainless steel solar pump and motor, max operating power up to 2450W (3HP)

Power Input: Solar DC 120Voc to 380Voc 1000Watt to 3500Watt, or AC 200 to 240V 50/60Hz
