Hi am trying to connect a 12v dc water pump to 220v power supply though a AC220v/DC12v 150w inverter. The pump was working but with a clear rhythmic tempo and not continuous. I checked pump with a 12v battery and it works perfectly and pumps strong and continuous . I checked the inverter and it states for led only. Clearly the LED part that causes the issue but not sure why. Could someone explain?
