I'm running a whole host of them on our buggy. They trip lickity split. This really is a case of an overabundance of caution. 270 watts of solar are installed on the level part of the roof (well, less maybe 5% of the 110 panel as it's approx 8 years old now). The future 320 watts of solar will be on the slight forward slope towards the front of the camper. Thus, when the sun is most ideal for the top panels, it will be slightly less ideal for the front ones, and vise versa. Also, unless the sun is directly overhead, there will be some amount of shadowing of the flat mounted panels dues to the huge AC assembly that lies between them. Thus, even in the most ideal conditions, I find it hard to image I'd pass the 30 amp limit, but, I suppose, it could happen. Better to be safe, I suspect. A 45 amp Morningstar would solve my concerns, but I need to start directing funds towards truck performance mods, and not another new controller (my current controller is near new and I have another still inteh box (which I ought to sell I suppose, but nice to have as a backup just in case). This is a simple $5 fix that comes with some peace of mind. Thanks again. This should explain what I'm talking about when it comes to shadowing, etc.
