Good Quality DC Submersible Solar Pump with Low Price (Controller inside the Motor)
Top Quality 4-Inch Submersible Solar Water Pump Solar Panels convert sunlight into electrical energy, which is then transmitted to the solar pump controller. This energy powers the pump efficiently. The Solar Controller / Inverter stabilizes the voltage and delivers power to drive the pump's motor. If backup batteries (optional) are available, the controller can also charge them. Batteries store excess energy for use when sunlight is limited. A Water Level Detector/Sensor connects to the controller, protecting the pump from dry running and automatically shutting it off when a water tank is full.
