This is the third portable power supply that I've built, 7S 24v 75ah 2KWh Battery pack with a 20 amp solar charge controller, 800w Inverter. Each battery pack has 28 cells, 2600mAh LG 75ah. I have 400w's of solar on my garage roof to charge this 4x100w Rich Solar Polycrystalline Panels, 2 in parallel 2 in series.

Nice looking build :)
I built two previously to this as I was learning and they were good but this one's has a much better layout. This one came out really well and it met all the specifications I needed and capacity test was more than 2 kW 2117Wh but that was at a fully charged of 29.4v for the capacity test. I'm only going to charge it to 28v when I actually use it.
