My Inverter Keeps Tripping or Reducing Power On Over-voltage.

So if your inverter trips on an ''over voltage'' error, the voltage where the grid connects in to your inverter has breached one or both of these limits. Note: The standard allows your DNSP to change these

Why the overvoltage tripping or power reduction occurs?

On a good solar day when no one is home, the system exports almost everything to the grid. The voltage is pushed up to 252V + 4V = 256V for over 10 minutes and the inverter trips.
