How to troubleshoot over temperature protection on my Hoymiles Inverter?
- L
  Lisa SavageAug 31, 2025
  To address the over temperature protection issue with your Hoymiles Inverter, you should: 1. Check the ventilation and ambient temperature at the microinverter installation position. 2. If the ventilation is poor or the ambient temperature exceeds the limit, improve the ventilation and heat dissipation. 3. If both the ventilation and ambient temperature meet the requirements, contact your dealer or Hoymiles technical support.

What should I do if my Hoymiles Inverter is showing a grid underfrequency alarm?
- R
  Randall ThomasAug 29, 2025
  If the Hoymiles inverter alarm for grid underfrequency occurs accidentally, the grid frequency may be abnormal temporarily and the microinverter can recover automatically after grid frequency becomes normal. If the alarm occurs frequently, check whether the grid frequency is within the acceptable range.

What does it mean when my Hoymiles HM-1200 Inverter shows a 'Rapid grid frequency change rate' alarm?
- T
  Teresa HardinAug 28, 2025
  If the Hoymiles inverter alarm for rapid grid frequency change rate occurs accidentally, the grid frequency may be abnormal temporarily and the microinverter can recover automatically after grid frequency becomes normal. If the alarm occurs frequently, check whether the grid frequency change rate is within the acceptable range. If not, contact the local power operator or change the grid frequency change rate limit via Hoymiles monitoring system with the consent of the local power operator.

What should I do if my Hoymiles Inverter shows a grid undervoltage error?
- V
  Victoria MedinaAug 27, 2025
  If the Hoymiles inverter alarm for grid undervoltage occurs accidentally, it might be a temporary issue, and the microinverter should automatically recover once the grid voltage returns to normal. If the alarm appears frequently, verify that the grid voltage is within the acceptable range. If not, contact the local power operator or change the grid undervoltage protection limit via Hoymiles monitoring system with the consent of the local power operator. If the fault still exists, check the AC switch or AC wiring.

What should I do if my Hoymiles Inverter displays a '10 min value grid overvoltage' error?
- D
  Dawn StewartAug 26, 2025
  If the Hoymiles inverter alarm for 10 min value grid overvoltage occurs accidentally, it might be a temporary issue, and the microinverter should automatically recover once the grid voltage returns to normal. If the alarm appears frequently, verify that the grid voltage is within the acceptable range. If it's not, you may need to contact your local power operator or, with their consent, adjust the grid overvoltage protection limit through the Hoymiles monitoring system.
