I'd go completely off-grid, and build in the redundancy ... everything ties into every stage of construction (plus, you have $30k to burn through, along with possible tax credit amount):
0. finish site planning ... where everything goes (roads, house, solar utility shed, septic, other desired structures)
1. put in roads (roadbase for now), get clearing done (firewise protection, fire road around perimeter of 10 acres) ... one bulldozer effort, done
- fire departments exist, but won't get to you quickly, so plan on your own response to things, until they get there
2. put in site propane tank (1000gal), heavy-duty propane generator ... now you've got site power, and backup fuel (propane lasts forever) for construction & future heating, and backup power (part of your solar gear)
- don't know if you've a wooded lot, but plan on wood stove, pellet stove, etc. (redundant heat system)
3. put in quality utility shed (not a man-cave, shipping container, etc.), but something that matches your house design, so it fits in architecturally
- minimum 8 x 16, but as large as you can afford
- holds water storage tank (500 gal), as buffer to your plumbing; have someone truck water in and fill it for construction
- holds solar gear on one of the walls
- panels go on ground near to the solar gear wall (usually your south-facing area, and why site planning is important)
- just far enough from main house to have fire separation between structures
- plan for fire connection on outside of shed, near water tank (you are remote, so you are the fire department)
4. add 48v solar inverter(s) & battery-bank
- I suggest pre-wired magnum or similar, as these are just rock-solid, and last forever (mine's 5+ years now); you are the electric company, so it has to be both bullet-proof, and family (kids) can operate it, and folks at support answer when you call for help
- could also be 6000xp's, as other threads suggest these scale as needed to fit power requirements; support might be iffy'er, but somewhat simple to just replace one (of 3 or more in your design)
- shed is insulated, so no problems with your LFP battery-bank (or your water) in winter
- you've got more power for both construction, and are running the generator less, but gen is still there for backups
5. add solar panels, whenever
6. build the big house
- all utilities are in, everything's been tested and kinks worked out
- you are still running power-wise (and water, and septic), when everyone around you is down (grid is down)
- tax credit gives you back some money (just need 1 solar panel, and everything else qualifies ... equipment, electrician installation costs, etc.)
- most efficient power devices you can find (mini-splits instead of central hvac, etc.)
- super-insulate (benefit heating/cooling)
- passive solar (might help with heating/cooling)
Main thing is, you are off-grid, self-reliant, and everything still works when the rest of the world is grid-down and going crazy. It is totally possible to get there, and cut the grid-connection and all associated headaches.
Hope this helps ...
