If I calculate it right, you are getting about 250 ah, or about 13kWh. Discharging to 25%, that implies 17kWh capacity.
Voltage chart to see if you are fully charging.
How about one per federal reserve bank district, or federal circuit court?
Also Radio Shack. They could have rebranded as Solar Shack if they survived a few more years.

I belive the reason victron is not more popular is that they are not UL Listed. They have CE for Europe, but not UL for USA.
For the cost of two victrons, you can get the 6000xp, which includes the charge controllers. If you need more power, you can parallel a second.
It would be easy to stay...
