Samcen solar pumping system serves to provide water in remote applications where electrical grid power is either unreliable or unavailable. Samcen solar pump controller can direct use the DC power from PV array, and drive the brushless DC pumps. In sunny days, the pumping system can continuously pump water. The system without batteries and other energy storage devices, it is recommended to take water pumped to a reservoir for later use and water sources are those natural or special such as river, lake, well or waterway,etc. A float switch can be installed in the water tower to control the pump operation. And install a low-level probe in well to detect the well water so that when the water shortage pump is stopped. Figure 1 shows a
typical diagram of the pumping system. The major parts and components in the system.
