Frequency Drifting up at No Mains in
I have a 5kW system running for about 2 years. The last 2 days the Inverter Output Frequency drifts to 55Hz during a power outage (50Hz system RSA). What could possibly cause this? Neutral Earth bond is good.

This would be the maximum frequency the inverter will reach if the grid is lost when the excess energy can not be absorb. When the Grid is connect the frequency will synchronise with the Grid.
@Jaco what is your AC Coupled Frequency setting?
