001Warning
GridOVP

The voltage of the power grid is too high

What you can do

  • This is usually caused by the mains supply, not the solar system
  • The inverter normally reconnects by itself once grid voltage is back in range
  • If it happens often (especially on sunny afternoons), note the times and call your installer - they can check the voltage and settings and talk to the network if needed
