I've been looking at less portable remote working.

I gradually moved away from larger and larger battery banks to a more DIY flavor, using lifepo4 batteries and inverters:

So this is AC -> battery -> AC but your DC setup should work too, skipping charging. The lifepo4 batteries have enormous capacity for not too much money.
