Are Tracer MPPT controllers (2215RN) actually better than PWM?

Thank you, after some more research and crunching some of the replies here, I think you have the right answer. Should be no problem with the better MPPT controllers that give you control via software/firmware over the output, but the cheap ones as always are on a case by case basis.
thanks

There is a fancier tracer that lists PV current limiting protection: http://www.amazon.com/EPsolar-Tracer...rge+controller

Thanks for that, I have been reading and learning a little more since my last question. Funny to see your location, I was up at 4:00am but did not have time to read your response because I was in a hurry to start my 800 mile solo drive (all today) to my mothers house in the foothills near your location. All loaded up in the car, turn the key, starts for 1 sec. and dies, (fuel pump out). Now I am relaxing catching up on e-mail instead.
thanks
