Nice. There's actually the $27 off code today that works with this though, USSS27. Had initially bought panels by themselves then saw how expensive mppt's were that weren't obviously garbage. Even Eco worthy's one here is like $120. Good deal.

How much would you say these 100w panels are worth subtracting the electronics? I've seen lots of 300W-400W panels selling on facebook market place in my local area for $120-$200 a panel. That would save tons of space on my DIY project.
