I want to run an idea by this group. I have a camper van with 300w of solar on the roof wired in parallel. I can get a deal on the same panels to add two more. With no room on the roof, I was thinking about doing a ground deploy. I was thinking about getting a zamp (SAE) external hookup and place it in the rear next to my AC shore hookup, then run a wire from there up to my roof combiner so I can use the same charge controller (100/50). Do you guys see any problems with doing this? I know adding another controller is the preferred method, but I've got a full electrical compartment and no room to add another controller. The panels will be the same spec so there shouldn't be differences between voltage. The only thing I can think would be an issue would be the voltage drop but with 10awg wire, I don't think that should be an issue with such a short run.
