My 4-12v 80ah AGMs are in and working nicely. Admittedly I could use more ah, but, these seem to be working just fine.
After a night of 5 hours of TV, I can easily brew coffee next am @ 1200w for 10 minutes without going below 24v. At 8am there's only minimal help from the sun.
Edit: Oh, and I was noticing the voltage was fluctuating by .1 volts, and when using the inverter the voltage was all over the place. Turns out I broke the 250a inline cat fuse, so I replaced it.
