GRID-OF

Grid Over-Frequency

Grid frequency has exceeded the upper limit (51 Hz UK). Inverter disconnects until frequency recovers.

Grid instability or DNO frequency eventTransient condition -- usually self-resolves
STEP 1
Wait 5 minutes -- inverter should auto-reconnect when frequency returns to normal
STEP 2
Check Anker app for frequency log to confirm event was transient
Fault recurring more than once per day -- log frequency readings and report to DNO
