Voltage vs. PWM controller & wire size
Ok, there is a recent thread out there MPPT vs. PWM and some post were a little confusing to me. Instead of hijacking his thread I started a new one. My set up is two 208 watt Sony panels with 28....

Nothing to lose, except for size/current efficiency. Those 208W look same large as mine 245W, and PWM will process less than half of available wattage.
If Trimetric clips it off like - apparently - it says in the manual, why only 3 panels, what is the purpose? To see if solar will make any energy? :) It will. 21A is a very modest system, even die-hard Handy Bob has 2 times bigger equivalent, considering tilt. Enough for a minimalist but not if you want to run your rig on solar the same way as on grid.
Thanks I keep that in mind.....I know you're trying hard to be realistic, but at the same time a Debby Downer.
