Tips: The protection functions of solar water pump and DC controller
- Over-current protection
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.
