Issues with inverters are often due to external influences, GRID VOLTAGE being one of these. Often a main line which either has several PV installations on it or is near a main transformer with see voltages around the 250 – 253 volts AC. These are on the operating upper levels and surges above this voltage will either trigger a fault code or an inverter to switch off (This will depend on the model and manufacturer but check the inverter specifications).

In the event that this is a common issue, then it may be possible to adjust the tripping point on the inverter but this should be done in consultation with the manufacturer who will advise on the best parameters.
