What does Grid Underfrequency mean on a Huawei SUN2000-60KTL-M0?
- DDanielle Meyers MDSep 4, 2025
If your Huawei Inverter displays 'Grid Underfrequency', it indicates that the grid frequency is lower than the local power grid standard. If it's an isolated incident, it might be a temporary grid issue, and the SUN2000 should automatically recover. However, if it occurs frequently, verify that the grid frequency is within the acceptable range. If it's not, contact your local power operator. If the frequency is within the acceptable range, consider modifying the underfrequency protection threshold with the consent of the local power operator.
