Solar Controllers--Don't be a Sucker! :(
Just got to say it again, how it is we are sitting here for five months off grid on solar with no problems at all (third season on solar like this), using the non-programmable, non-MPPT, solar control...

Going from 6 amps to 20 amps would be exciting! That was right after he sawed the girl in half and pulled a rabbit out his hat I guess. :)
Meanwhile, it is still the case that two 12v 120w panels that have Isc of 7.6a will get you 15.2a with PWM and jimindenver's 235w 24 with MPPT gets him max 15a too. (others get 15a but with a 15L controller that clips the amps at 15, but he has a 20a controller, so no clipping keeping it down to 15.)
