About this chapter
This chapter describes the pump control features of solar pump inverter. Each feature
includes a list of related user settings, actual signals, and/or fault and alarm messages.
Dry run function
The solar pump inverter trips to a
when the water flow is not available at the
pump inlet or when a blockage occurs in the pump. During these conditions the inverter
consumes less current than the minimum load current (
) or the
actual motor current is lower than the minimum load current for the defined trip time.
Note
: The dry run function is disabled during the initial start up time.
