Solar Generator Troubleshooting

Solar generator is an environmentally friendly, renewable energy generation equipment, but in the process of use, it is inevitable to encounter some malfunctions. will introduce common problems and provide solutions in the use of solar powered generators to ensure the normal operation and safe use of the equipment.

Common Malfunctions of Solar Generators

Solar Panel


  • Output power is not up to the desired power.
  • Abnormal fever.


  • Place the panel in a sunny place and adjust the tilt angle; clean the dust or snow on the layout; check the internal wiring for shorts or breaks, and replace the connector if deterioration occurs.
  • Check the back sheet and bracket for poor contact or other mounting problems, and for rubbing on foreign objects. Under abnormal temperature environment, special attention needs to be paid to whether the heat dissipation system of the panel and generator is functioning properly.

Fixing solar panels



  • Unable to charge.
  • Overcharging or undercharging.
  • Sudden drop in power generation.


  • Check whether the connecting cables of the whole solar energy generator system are loose or damaged, and repair or replace them in time; check the condition of the electrolyte, and add or replace the battery in time if the electrolyte is lost or seriously lacking.
  • Use a solar charge controller to control the voltage and current from the solar panel. Control the charging and discharging time according to the device manual.
  • Check the battery charger for charging abnormalities.



  • Inverter screen does not display anything.
  • DC voltage too high alarm.
  • The overheating protection function is activated suddenly and autonomously.


  • Check whether the voltage is insufficient, whether the connectors are all connected, whether there is a short circuit in one of the components.
  • The excessive number of components in series causes the voltage to exceed the tolerance range of the inverter. If this occurs, the voltage of the solar generator should be reduced appropriately.
  • Check whether the heat dissipation system is working properly and clean the solar panel.

Malfunction Caused by Weather


  • Storms or blizzards cause damage to equipment.


  • Pay attention to the weather forecast and put your solar generator away or cover it in time when there is an extreme weather warning.

Maintenance Process

  • Troubleshooting and Diagnosis: After preliminary judgment based on the fault phenomenon, use test instruments to measure and check the key parts.
  • Repair and Replacement: Take appropriate repair measures according to the cause of the fault. If parts need to be replaced, detailed steps and precautions need to be understood.
  • Testing: After repairing, the repaired parts should be functionally tested to ensure proper operation of the solar generator.

How to Prevent Malfunction

  • Clean the solar panel regularly and check whether the screws, circuits and cables are loose, etc.
  • Check the working condition of the inverter and batteries regularly to detect problems and repair or replace them in time.
  • Avoid using the solar power system in bad weather conditions to avoid damaging the components. Also, avoid excessive power usage and power waste at night.

Troubleshooting of solar generators is an important part of ensuring the safe operation of the equipment. By understanding and adopting corresponding s-olutions, we can solve equipment malfunction in time and prevent accidents. At the same time, paying attention to weather factors and correct operation can also effectively reduce the probability of malfunction. In the process of u-sing solar generators, maintaining safety awareness and operating in strict ac-cordance with the manual will help prolong the service life of the equipment.

If there are more problems or need for repair, please contact the relevant m-aintenance department in time.
