For my setup I have gone with running 3 (yes, lol) smart MPPT 75/15's (due to different orientation and panel sizes so they can cover my entire van roof)
I have read that they will work nicely in parallel after being linked via bluetooth and the BMV 712 smart monitor/shunt to coordinate them). It seems difficult to see info on what to do with the load outputs. I am wondering if I just select one to be the load output "master", or if I need to link all three of them to my load?
Any additional reading and info is most appreciated,
