My System is pretty Ghetto. I added 8 x DJLBERMPW 12V 100 AH LifePo4 batteries for 1,444.78 after taxes off amazon, which is equivalent to 2 51.2 v 100 amp batteries. I know they are cheap, but they're working fine so far, and staying top balanced to each other. I did initially order two of the AOLithium 51.2 Volt Server rack batteries but they cancelled my order as they oversold their stock. Anyway, I doubled my battery capacity with those, so have 20Kwh's now, which means my array is puny in comparison, I have 1200 more watts of solar panels, that aren't installed yet, which will bring me to 3.6Kwh's of panels, which is still small for 20Kwh of batteries. I plan on getting that system up to probably 5Kwhish of solar panels, So, a max of .25C charging at optimal conditions. So, still pretty gentle on the batteries, as 90%+ of the time it'll be less than .2c rate, and really less than that as I use some of the power as generated as run some loads off it 24x7.
I also upgraded my BMS on my other 10Kwh of batteries to an OverKill solar BMS, which is better than antbms I had before.
I also stopped being completely psycho with my setup and added some more breakers and fuses this year. Flirting with disaster to long. lol.
Next year best thing will likely be cutting down a tree, that is stealing my solar power for a couple hours in the morning!! I'll likely get a couple more Kwh's per day doing that.
