Growatt Inverter Faults and error Code

It’s important to note that what are the common faults with growatt inverters? If you have any questions about growatt on grid inverter and grid phase error growatt, contact our consultants.

Growatt inverter faults and error code table is as follows, you can have a quick growatt inverter troubleshooting:

Error Code Description Troubleshooting

Growatt Inverter No Ac Connection

No utility grid-connected or utility grid power failure

This error normally happens during a grid failure, if you still have electricity connected to your property, then you must check your AC isolator or circuit breaker. If both the isolator and CB are ‘on’ and the problem continues to submit a maintenance service request.

 

No Power Output

When the solar inverter shows no power output, that is going to leave your solar panels inactive. possible cause: 1. Grid Disconnection 2. Inverter Failure 3. Faulty Wiring

1. Checking the connection to the solar grid
2. checking the inverter for error codes or messages
3. if the issue continues, contact an expert for further diagnostics

Low Power Output

When the solar inverter is working, it is not generating the expected amount of power, which results in reduced energy production. possible cause: 1. shading 2. Dirt AND Dust 3. inverter efficency 4.Panel aging

1. conducting a shading analysis and removing objects that are blocking the sun
2. Cleaning the solar panel according to the manufacturer’s cleaning guidelines.
3. Scheduling regular maintenance visits in order to replace any worn-out or underperforming parts 4. Monitoring the inverter’s efficiency using the display or using an online monitoring system.

Inverter Error Codes

When your solar inverter displays error codes, it is pointing to a malfunction or issue in the system. possible cause: 1. Internal Faults 2. Software Updates 3. Electrical Issues

1. try checking the inverter’s manual to understand the error code’s meaning.
2. In case of internal faults, you must consult an expert technician or the manufacturer for repair or replacement options.

Overheating

When the solar inverter turns excessively hot, it can be a safety concern and cause performance issues. possible cause: 1. High Ambient 2. Temperatures 3. Inadequate Ventilation 4. Dust and Debris

1. Make sure the solar inverter is installed in a well-ventilated location.
2. Regularly clean dust or debris from the solar inverter’s vents.
3. Installing a shade or a form of cover to protect the inverter from direct sunlight.

Ground Faults

When ground faults occur, they can cause electrical safety problems and may result in your inverter shutting down. possible cause: 1. Moisture and Corrosion 2. Wiring Problems

1. Check the wiring for loose or damaged wires
2. Since both wires and connections must keep dry, address moisture and make sure they stay dry.
3. check for signs of corrosion regularly and replace any corroded part.
4. if the issue continues, contact an expert for further diagnostics
