Well.. let us call it..Got Deye12K to my FIL and he is going to connect 6,6kWp to MPPT1 and his old 3kWp array to MPPT2. Now he wants to add more panels to MPPT2 with 180 degree difference in azimuth (adjacent slope in his roof) by paralleling strings and wants to use 3-way split with MC4 connectors including diodes in both strings leads. This is supposed to prevent strings fighting each others when other is in sun and the other isn't. I told him it's a bad idea, but then what would I know...
Anyone?
