If the mains voltage above 253V comes, the inverter switches itself off to prevent damage. This is common in areas with many solar panels.

Causes:

• Many solar panels nearby → The grid gets overloaded.
• Long or thin cables → May cause voltage drop.

Possible solutions:

• Adjusting inverter settings → Some inverters can handle high grid voltages better.
• Use thicker cabling → Reduces voltage drop.
• Considering a battery storage unit → To store energy locally instead of feeding it back.

Contact grid operator → Sometimes the grid operator can fix the problem.
