July 9, 20242 yr Hi. I have a Deye 8Kw inverter with two mppt strings and two 5Kw batteries. Been working fine for 18 months. Suddenly I have a F26 fault which I managed to rest once and it came back again after a couple of hours. Does anyone have any suggestions to resolve this issue. The inverter works like a bypass for mains power when this fault is present with no loads shown.

July 9, 20242 yr Author I am told it may be due to an earth fault on one of the MPPT strings. Managed to reset the inverter with the DC turned off. I will keep you posted.
