What to do if my Hoymiles HAT-5.0HV-EUG1 Inverter shows Grid Overvoltage?
- SStephanie ShawAug 22, 2025
If your Hoymiles Inverter frequently shows a Grid Overvoltage alarm, it means the grid voltage is higher than the permissible range. While the inverter typically reconnects after the grid recovers, you should: 1. Ensure the inverter's safety country setting is correct. 2. Confirm your area's grid voltage is stable and within the normal range. 3. Verify the AC cable's cross-sectional area meets the requirement. If the alarm persists, further assistance may be needed.
