Solar plan
i read all of the posts of the solar installs and try to read everything that comes through. I didn't buy a trimetric or anything else to measure my use but some suggest matching it to the battery amp...

I should add to my comment about my gc2's being turds. I'm just joking around and would possibly buy them again. They have done well for us. In fact I have commented on here in the past about a set of 4 group 27's that I run in series in a 48 volt electric pontoon boat. Those are also considered cheap batteries but I have charged them with a Lester 48 volt industrial charger that regularly hits 61 volts. They were purchased in the summer of 2008 and I just put them back in the boat after leaving them on a battery tender for 7 months. One of them died last fall and I put a like size gp 27 from 2012 in the mix. so 3 are from 2008. That little tender kept up all 4 in parallel with a sg of 1.280.
