What to do if my SMA 10000TL Inverter shows VpvMax or Vpv-Max error?

If your SMA Inverter displays 'VpvMax' or 'Vpv-Max', it indicates an overvoltage at the DC input that may damage the inverter. Immediately disconnect the inverter from the grid by: 1. Turning off the line circuit breaker. 2. Removing the Electronic Solar Switch. 3. Disconnecting all the DC plug connectors. Next, check the DC voltage. If it exceeds the maximum input voltage, check the plant design or contact the PV generator installer. If the DC voltage is under the maximum input voltage, reconnect the inverter to the PV generator. If the message occurs again, disconnect the inverter and contact the SMA Serviceline.
