Chapter 1 How It Works
The PDS23 solar pumping system serves to provide water in remote applications
where electrical grid power is either unreliable or unavailable. The controller can
convert DC from the PV array to AC，and drive kinds of pumps. In sunny days, the
PDS23 solar 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 a PDS23 solar pumping system. The major parts and components in the
system are listed after the diagram.

The PDS23 solar pumping system is designed which consists of:
A. Solar Array
B. DC Breaker or Disconnect Switch
