Bit 14 Error: Solar Panel Pump System

I am facing Bit 14 Error problem in my solar power driven ‘Solar Panel Pump System’. It is very confusing problem in a solar PV system.

Major issue	Saur sujala yojana
Related field	Agriculture, Horticulture, Farms.

Common problem in a SPVP system are as follows:

Fault 01	Bit 14 error
Fault 02	Dry run pump or dry pump run
Fault 03	Pump stuck
Fault 04	Low voltage

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 02: Dry pump run problem

Problem

• After starting the pump, the ‘Run LED’ shows green for a while.
• ‘Red LED’ start to display red colour.
• ‘Dry Pump Run’ appears in display LED.

Causes

• There is no connection between the solar panel system and submersible pump.
• There may be a loose connection.
• The formation of layers of carbon is also a problem.

Troubleshooting

• Make sure a connection between the solar panel system and submersible pump.
• Tighten the loose connections.
• Clear the layer of carbon.

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.
