Ok here's why your DC connect idea is not such a great idea:

1. DC power equals big wires. Low voltage high current. Which induces loss at the square of the current per unit length. High voltage low current equals less power losses but way more deadly.

2. Everything tied to the DC feed must operate at that voltage or be converted. Yes, even battery banks need a charge controller. When the sun goes down, none of that dc stuff will work without being backfed from another power source.

3. Battery banks ain't cheap. Running night after night will wear them down in a few years. Then you get to buy new batteries.

It all depends on details and intentions. Being grid independent is satisfying but expensive.
