4DCSP
4" DC Brushless Deep Solar Well Pumps

Installation and use:
The complete solar pump system consists of a solar panel, control box, and submersible pump. This submersible solar pump harnesses solar energy to draw and deliver water, making it an ideal solution for water supply in sunny regions, particularly in remote areas without access to electricity. It is primarily used for domestic water supply, agricultural irrigation, and garden watering. In addition to the pump and renewable energy source, solar water pumps come equipped with all necessary control, communication, and auxiliary components, providing a comprehensive system. This system can be customized and adapted to meet specific needs, aligning with the conditions of the installation site. The diverse energy options and performance capabilities offer significant flexibility.
