Hello this is my first post thanks for adding me.
I am new to solar and I have been gifted 2 panels for use on my camper. They are both cheap 40w panels with thier own charge controllers.
my question is whether I should wire them in parallel into a single charge controller or whether I should simply connect both charge controllers to the battery.
one panel is a polycrystalline panel with optimal voltage of 17.1 the other is a mono crystalline panel with optimal voltage of 15.9.
I have read that it it's not good to connect different voltage panels together but you can get away with it if they are close enough. The charge controller I wish to use is a Coleman 7amp unit the other one is "competition solar" brand with no ratings on it and it feels quite cheap and much lighter than the coleman with only a single led indicator.
I'm wanting to charge a single 135ah deep cycle battery.
would I have more losses using 2 separate charge controllers or wiring 2 similar voltage panels into a single (what I feel is better) charge controller.
thanks in advance
