      Hva betyr feilmeldingen på min Growatt-inverter?

      Growatt inverter feil og feilkoder gir verdifull informasjon om statusen og ytelsen til inverteren, samt lar brukere feilsøke eventuelle problemer som kan oppstå.

      Growatt-omformere er mye brukt i solenergisystemer for å hjelpe til med å konvertere likestrømmen (DC) fra solcellepaneler til vekselstrømmen (AC) som kan brukes i hjem så vel som bedrifter. i denne artikkelen skal vi introdusere deg de viktigste growatt-inverter-problemene og growatt-inverter-feilkodene.

      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
