mppt is stuck
A friend recently had a 12kw 3 phase installed along with 11kw of panels which are split into 2 strings.
His roof is a mess in terms of it being an old house with many roof sections pointing all over the place.
There was an issue with some wiring on string/mmpt 2 which is all sorted and output from that string is good BUT string 1 seems to be stuck in low output mode.There is shading on string 1 but the output has got worse.
I was wondering if an inverter reset might work.
There was an article on this issue but I cannot find it
