How It Works
The PDS33 solar pumping system serves to provide water in remote applications
where electrical grid power is either unreliable or unavailable. The controller can
convert DC power from the PV array to AC power
，
and drive variable kinds of
pumps. In sunny days, the PDS33 solar pumping system can continuously pump
water. The system is without batteries and other energy storage devices, it is
recommended to take water 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 PDS33 solar pumping system. The
major parts and components in the system are listed after the diagram.
