Meaning
Grid fault AC sources in the system are driving the generator. The reverse power in the generator has been exceeded for too long. Corrective measures: Adjust the generator request to the properties of the AC sources in the system and the loads, e.g., for PV inverters, preferably request the generator at night. If the generator can absorb reverse power, adjust the settings for reverse power ( > Changing the Permitted Reverse Power in the Generator)
