The pump does not start or delivers too little water

If your pump does not start, or delivers less water than expected, please check the following:

Solar Module

  • Check whether all plugs are connected correctly
  • Check whether there is enough irradiation
  • Check whether the PV modules are dirty, shaded or not facing towards the sun
  • Check whether the modules are connected in a correct way, check the input voltage of the controller
  • Check whether the connected solar modules have enough power/voltage

Controller / Wiring

  • The plugs are wet or have not been inserted properly
  • The controller is too hot and needs to cool down

Pump / Hose

  • Is the pump submersed in the water? Check the water level (dry running)
  • The pump is clogged with mud or sand
  • The hose or pipe is blocked, twisted or kniked
  • The water temperature is too high, the pump will stop or not start → check the temperature class of your pump
  • The water temperature is too low → the flow is reduced
  • The pump was exposed to the sun and is too hot
  • The lift is higher than the head range of the pump
