It can be annoying when you cannot generate power and feed it back to the grid. Below is a description of what you can do.
Use power at the moment of generation
At times when there is a lot of sunshine, it is important to consume power precisely at that time. This reduces the chance of the inverter failing. Run laundry, turn on the dishwasher or charge your electric car.
Call a professional installer
Have your installation checked by a licensed installer. The installer can fix the failure if the solar panels and/or inverter are not properly installed or if there is not a proper distribution of power across the 3 phases of your electricity connection.
Check for voltage problems
Voltage problems often occur on sunny days. This is when a large peak of generated energy comes onto the grid, causing the grid voltage to rise. The inverter of your solar panels may then switch off temporarily. Check with your grid operator if there are voltage problems at your address.
Report the problem to your grid operator
Make sure that your grid operator is aware of the failure. They can place extra (thick) lines and transformers in areas with solar panels to stabilize the voltage.
Why is my inverter indicating malfunction?
A grid voltage that is too high may cause the failure. The inverter of your solar panels switches off automatically when the voltage in your home is too high (above 253 Volts). This is regulated by law and described in the standards of an inverter.
If the inverter does not switch itself off automatically, the inverter or other equipment in the house could break down. As soon as the voltage drops back to a normal level, the inverter (usually) switches itself back on.
