I3SS Built-in MPPT Controller 3 inch Solar-Powered Helical Rotor Submersible Borehole Pump Screw Pump
The Built-in Controller type 3-inch Solar Powered DC Screw Submersible Bore Pump is designed for reliable water pumping in off-grid locations. Powered directly by solar panels, this solar bore pump eliminates the need for traditional electricity or fuel, making it an eco-friendly and cost-effective solution.
Equipped with an MPPT controller and a brushless DC motor, this solar dc submersible water pump ensures maximum energy efficiency and stable operation. Its DC screw type design allows it to maintain consistent water flow even in deep wells or low-yield water sources, reducing maintenance needs.
This durable and versatile DC pump is ideal for agriculture irrigation, livestock watering, and rural water supply projects. Whether for farms, gardens, or remote communities, the brushless dc solar water pump provides a sustainable and long-lasting water pumping solution.

System Wiring Instruction
Solar Panel
● Connect the solar panels accurately according to the product manual, as excessively high VOC voltage may cause irreversible damage to the controller.
● It is generally recommended to calculate the required solar panel power based on 1.3 to 1.5 times the rated power of the water pump.
● When connecting the solar panels, ensure that the VOC voltage of the solar panels does not exceed the maximum VOC voltage limit of the controller.
