What to do if Hoymiles HAS-3.0LV-EUG1 Inverter displays Grid Overfrequency?
- H
  Heather WashingtonSep 12, 2025
  If your Hoymiles Inverter frequently shows a Grid Overfrequency alarm, it means the grid frequency is higher than the permissible range. While the inverter typically reconnects after the grid recovers, you should: 1. Make sure the safety country of the inverter is set correctly. 2. Make sure that the grid frequency in your area is stable and within the normal range. If the alarm persists, further assistance may be needed.

  Michael SextonAug 25, 2025
  If your Hoymiles inverter frequently indicates a 'No Grid' error, it means the inverter isn't detecting a grid connection. While the inverter typically reconnects automatically once the grid is restored, frequent alarms suggest: 1. Check if the grid supply is reliable. 2. Ensure the AC cable is firmly in place and correctly connected. 3. Verify that the AC circuit breaker is not disconnected. If the issue continues, consider contacting Hoymiles technical support.

What to do if Hoymiles HAS-3.0LV-EUG1 Inverter shows Grid Undervoltage?
- I
  ilunaAug 26, 2025
  If the Hoymiles inverter frequently reports a grid undervoltage error, it means the grid voltage is lower than the permissible range. While the inverter should automatically reconnect once the grid voltage returns to normal, frequent alarms suggest: 1. Make sure the ESS safety configuration of the inverter is set correctly. 2. Make sure that the grid voltage in your area is stable and within the normal range. 3. Check whether the AC cable is firmly in place. If the problem persists, consider contacting Hoymiles technical support.

Why is my Hoymiles Inverter showing an RCD Fault?
- J
  Jack AustinAug 26, 2025
  An RCD fault on your Hoymiles inverter indicates that the residual leakage current is too high. This can be caused by high ambient humidity; the inverter should reconnect to the grid once the environment improves. If the environment is normal, check whether the AC and DC cables are well insulated. If the alarm persists, contact Hoymiles technical support team.
