Hi,
I have two sided of roof, one pointing almost West, one almost East, (20 degree turned towards east) (location is Denmark) see picture here :
My plan was : 3,7Kw array on West and 2,8Kw on east, my reasoning was that we consume more energy towards the end of the day than in the morning. I am planning doing a DC and AC coupled system using Multiplus II, Fronius and a Victron MPPT.
My plan was to have one side on the Fronius and one side on the MPPT but somebody suggested to different.
He suggested take half East to Fronius MPPT1, half West to Fronius MPPT2 and the rest from West and East in parallel to the Victron MPPT. He said it's better to do this because the MP2 can only charge with 1.5kw on the battery from AC (if there is surplus from Fronius).
Why is that a good idea ?
Here is a full diagram
