Chapter 1How It Works
PDS23 Plus solar pumping system serves to provide water in remote applications
where electrical grid power is either unreliable or unavailable.PDS23 Plus solar
pump controller can convert DC from the PV array to AC, and drive kinds of 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 thatwhen thewater shortagepump is stopped. Figure 1 shows a
typical diagram of the pumping system. The major parts and components in the
system are listed after the diagram
