F45 over volt fault
Hi, I had this fault over the weekend on my 8.5kw system as it approached 7.5kw for the first time since installation in January. I have 21 405w panels across 3 strings into the 8.8kw inverter. I assume it must have 7x panels going into one string and another 14x going into the other.
If this is the set up for the strings, could that cause the fault code?

Alternative option would be to split the 14 panels to two 7 panel strings and parallel them. As the inverter input current is 22A it should work without clipping as the NOCT current for the panels is 10.40A.
Probably slightly harder to do using a ladder though.
