If your inverter is no longer working, first try the following steps:

1. Check the fuses – Have the fuses in the meter cupboard or the inverter itself tripped?
2. Restart the inverter – Turn the inverter off, wait a few minutes, and then switch it back on.
3. Check the error code – Most inverters display an error code on the screen or in the monitoring app. Look this up in the manual or online.
4. Check the grid voltage – If the grid voltage is too high, the inverter may shut itself down.

Does the inverter remain off or does the error message persist? If so, there may be a technical defect and professional help is required.
