PDS23Plus solar pump controller runs at variable speed while match the changing
power provided by the solar array. Variable speed operation means there is no
in-rush or surge of energy during the pump/motor start-up, helping to eliminate wear
on the motor and pumping system.
Pump Check Valve Requirements
Notice:
In order to ensure maximum system reliability and water delivery, check
valves must be installed in the drop pipe. The first check valve must be installed at
the pump and additional check valves should be installed every 30m (100 ft) of
vertical pipe after the pump.
1.1 Features
System Diagnostics
PDS23Plus solar pump controller continuously monitors system performance and
detects a variety of abnormal conditions. In many cases, the controller will
compensate as needed to maintain continuous system operation; however, if there
is high risk of equipment damage, the controller will protect the system and display
the fault condition. If possible, the controller will try to restart itself when the fault
condition subsides. See diagnostics and troubleshooting section for a list of fault
codes and corrective actions.
Motor Soft-Start
Normally, when there is a demand for water and power is available, PDS23Plus
solar pump controller will be operating. Whenever the controller detects a need for
water, the controller always “ramps up” the motor speed while gradually
