The screw terminals actually clamp down tight on 10 AWG wire, which was my worry with cheaper units. Been running it a few weeks now and my 12V battery tops off earlier in the day than it used to.

Wired this between my panel and a 12V battery and it's been holding the input steady all week, even on cloudy afternoons. The pre-installed wiring made setup way less annoying than I expected.

Paired this with my 12V battery and a 100W panel and it's been holding the charge steady for about three weeks now. The pre-installed wiring made setup quicker than I expected, though the screw terminals are a bit fiddly to reach in tight spots. Solid little unit for the price.
