What does '10 min value grid overvoltage' mean on my Hoymiles HMS-2000 and how to fix it?

  If you occasionally see the '10 min value grid overvoltage' alarm on your Hoymiles Inverter, it might be due to a temporary issue with the grid voltage, and the microinverter should automatically recover when the voltage stabilizes. However, if this alarm appears frequently, check to ensure the grid voltage is within the correct range. If it's outside the range, contact your local power operator or, with their approval, adjust the grid overvoltage protection limit using the Hoymiles monitoring system.

Why does my Hoymiles Inverter show grid overvoltage?
- R
  Ryan MitchellAug 13, 2025
  If the grid overvoltage alarm occurs occasionally on your Hoymiles Inverter, it could be due to temporary grid voltage fluctuations, and the microinverter should automatically recover once the voltage returns to normal. However, if the alarm appears frequently, verify that your grid voltage is within the acceptable range. If it's not, you should contact your local power operator or, with their consent, adjust the grid overvoltage protection limit through the Hoymiles monitoring system.

  First, ensure that the Hoymiles microinverter is functioning correctly by checking if the DC voltage is within the normal range and verifying the LED indicator status. Next, confirm that the serial number (SN) on the microinverter label matches the one on the monitoring platform. Then, check the communication status between the DTU and the Hoymiles monitoring system, as well as between the DTU and the microinverter itself; if the communication is poor, try to improve it.

  Kevin DaviesSep 2, 2025
  Check the ventilation and ambient temperature at the microinverter installation position. If the ventilation is poor or the ambient temperature exceeds the limit, improve the ventilation and heat dissipation.
