Controlling mismatched panels on my RV
Hi, I appreciate the help this forum has provided (I posted a question last week and you resolved that issue. Now I have another stupid question. I currently have 2 85w PV panels mounted on my RV. I want to add 2 120w PV panels (totaling 410w). I am going to replace my controller (currently a Thunderbolt Magnum 30w) as I don't trust it. I am looking at a Schneider 35w PWM. I have received conflicting opinions on controlling mismatched panels. One source says a PWM will control all 4 but will knock the 120's down to about 100. They recommend a MPPT. Another source says an MPPT does not do well with mismatched panels and that I should use a PWM. Any help would be appreciated.
