Fault 01: The bit 14 error problem

Problem

  • After starting the pump, the ‘Run LED’ shows green for a short time.
  • Not enough power is generated to run the submersible pump.
  • ‘Red LED’ start to display due to not enough power being generated.
  • Bit 14 error appears in the display LED. Water does not come out of the borewell.

Cause

  • “I’m still trying to find the cause of this problem”.
  • “After finding the cause of this problem, I will share it”.

Possible reasons

The reasons of this problem may be one of the following:

  • Faulty cable.
  • Faulty wiring.
  • Short circuit in control unit.
  • Short circuit in micro inverter.
  • Faulty capacitor.
  • Damaged PV panels.
  • Faulty PV panels.

I have found the main cause of this problem. The main cause of this problem is short circuit. This problem occurs when the two live wires come in contact with each other.

Fault 03: Pump stuck

Causes

  • Due to the sand and pebbles getting trapped in the submersible pump, the pump cannot spin or rotate.
  • This action prevents the uptake of water.
  • Technical fault in pump.

Troubleshooting

  • Clean your submersible pump set.
  • To troubleshoot the technical fault, contact a pump repairing service center.

Fault 04: Low voltage problem

Causes

  • Cloudy weather: No light due to cloudy weather.
  • Shades: Situation of over-shadow due to big trees.
  • Installation of photovolatic panels in wrong direction.
