A 100w panel costs about $100. Are you really going to spend $600 on a controller for $300 worth of panels? Sigh. You can run 300w with a 30amp PWM controller that costs maybe $50.
It is not sounding very worthwhile. Chose 100w panel to be able to mount 3ea permenant on "rover". If set-up is portable can use larger panels. Yes, MPPT would be more expensive but in 3-4 years if my solar set-up needs do change that is one piece of equipment that I should never have to toss in the corner. Who knows if I will always be able or want to locate the controller close to the battery bank. Flexibility is still much desired.
