MPPT 250/60 with 6 series of 360 cells

I want to rearrange the array to have 6x2 instead of 3x4 right now. The specs says I can have up to 360 cells which is exactly 60cells x 6 panels in series. The panels are Renogy 320W. Please advise if I can do that without going over the open voltage limit of a MPPT 250/60 controller. Thanks

With a Voc 40,1V and a Temperatur Coefficient you exceed the 250V already at +9°C.


Your desired configuratiob is definitiv only suitable for the Sahara!


With 5 modules you can go down to -54°C which is suitable for deepest Winter, but not Syberia... LOL
