Babock,

Great!

A link that takes me to a test of tires. LOL you certainly do know how to help others learn.

I was hoping that with your VAST knowledge, you would know of some non laboratory real life testing.

Worked for me. This is the first link offered.
Tested PWM versus MPPT

Here is the short and sweet of it:

good one, notice how they don't show perfect weather... two reasons, 1 much smaller difference between the two, and
2 when do you every have perfect weather when you camp [emoticon]

the only thing I wish they would have shown is when trees cast shadows over the pannel so you have 1/2 the pannel shadowed out, that's the biggest difference.

Gotta love the BS that people think. He tested it with the weather he had at the time. Was May in Maine!

I actually like that test, so not sure what your going on about. I just wish he had good weather so he could test the difference when it was partial shaded to show where the MPPT really shines. I have always said the MPPT is a better unit if you are set up properly, hence why I am building my campers system with a MPPT instead of the PWM they put on my 5th wheel.
