I just added a 300w Renogy system with the Rover 40amp MPPT controller (which seems to be doing really well so far in my test "driveway camping"). I am trying to decide if I want to add a 4th 100w panel to the roof or go with a portable to be take more advantage of being able to angle it to the sun. The 300w would bring the batteries back to 100% each day after spending the afternoon/night in the travel trailer when outdoor temps dropped to the 30's each night (middle TN in December), so the furnace was def. running, plus I pushed it by having the TV on the inverter (cheap ole 150w model) for a couple hrs each night. I did this 2 days in a row to see how the panels were doing recharging the batteries. They seemed to do pretty well, but I'm sure another 100w would reach float faster and maybe get them to true full charge each day.
I am probably over thinking this, but what is the best way to connect a portable solar kit to a travel trailer where I have 300w solar on the roof with 40amp mppt charge controller?
Do I connect the portable to the charge controller PV in (with the lines from the roof mounted panels) or just use it like it was designed and connect it to the batteries directly?
I'm thinking it would be better to add it to the input of the charge controller so I get a total input higher, rather than it essentially working against each other since both would be supplying current.
