Tips: The protection functions of solar water pump and DC controller
When the solar water pump model is mismatch, or UVW three-phase in short-circuit connection. Phase protection
UVW three-phase is in open circuit. Stall protection
When the pump model is mismatch. Pump extension cord is too long. Solar water pump power is too low. Pump bearing is stuck. Low voltage protection
The input voltage of solar pump is too low. High voltage protection
The input voltage is too high. Dry-run protection
Not all of air in the pump is exhausted. There is no water in the deep well/pond. High temperature protection
The temperature of DC controller MCU is more than 90℃. Reverse connection protection
The wiring is wrong.
