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...

20% of battery charging time could be in boost mode, while 80% is in absorption. That means you're only using the mppt feature for only 20% of the daily charging cycle. If you're in boost for 3 hours with mppt, then you're only 3.15 hours @ 5% gain or 3.3 hours @ 10% gain when using pwm. The rest of the time both systems charge at the same rate. MPPT is getting plenty of hype.

This statement may be in reference to your experiment, but if it meant to be a general truth it certainly is not my experience. Of the more than 12 hours my system is charging these days, at least eight are in MPPT. There again it may be different for 24-volt panels.
