Hello,
I'm trying to design E/W panel arrangement system with 3 panels per side. There's no room to add more panels.
Panels have 38V OCV.
Now, the date sheet for H1/AC1 inverters states the start up voltage is 75V, so in theory 3 panels per MPPT should work. In practice, does anyone have an experience with similar setup?
Many thanks
Mike

It's awfully close, any shading, low elevation, cloud etc.. will suppress the panels and delay startup - normally I would recommend a minimum of 4 panels.

Could you not put all 6 on a single string but fit Tigo TS4 optimisers to each panel ? - that should give you the best chance of reliable operation.
