I have 2 MPPT 75/15 controllers, each connected to two parallel 12V(18V)/100W panels. Battery is 12V.I would like to increase the system with two more 100W panels. But I am thinking of using 36V panels instead of 12V, as the cable losses would be lower and connect these panels to one additional controller. The controllers are interconnected by VE smart networking. Will there be any problems with the synchronised charging in this setup?
