          Understood. Solar power may be an asset, actually. And our grandsons want our lodge in perpetuity after Mia and I pass on. 
           1/2 mile to the nearest pole is just the start. That pole is over a mile from the nearest paved road, and only 2 huge hunting camps are on the line, and we are the 1/2 mile beyond that. The last big wind storm we had took out that line, and at lowest priority, took over 2 weeks to restore. 🤪

    You sound like a candidate for offgrid from what you said above. You should still do the model on costing. The number of full time people is often more of a driver in in system size than energy usage. You already know you are going to do this right and not make the dumb mistakes like an electric range and dryer.

    There is not much in life quite as sweet as living offgrid in a beautiful place. At least we think so!

    I was just explaining a system to someone looking at an off grid home 'done right'. Super insulted, earth contact, Iron Edison batteries. They  dropped the price $50K after 9 months of being listed;

    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Prosine 1800 and Exeltech 1100, 660 ah 24v ForkLift battery. Off grid for @16 of last 17 years. Assorted other systems, and to many panels in the closet to not do more...lol

    True, Dave. This is the type  of location that we've been looking for for 30 years. It  is beautiful. I just wish that my parents were around to see it. My dad was a licensed realtor and helped us look for an opportunity like this. I don't think that resale will be any problem for the grandsons should they become desperate many years from now. 😁

    Wow! Dropped $50k after 9 months! I guess that not everyone is looking for a system that needs maintenance and periodic battery and electronics replacements.

    Iron Edison makes both a super efficient LFP and the old school NIFE batteries that are super low efficiency. I may be wrong but when I first saw the NIFE bats they were being sold as doomsday batteries. You could "rebuild" them as Mike has here on the forum. Dr. Strangelove has them I hear ;)

    NiFe batteries are lower efficiency than flooded lead acid, but they are not super low !  I never worry about sulfating the batteries.  Winter cloudy spells were a major factor in choosing NiFe batteries.  
    When I started, LFP was not an option yet.  With 10 years of history, I have only had the batteries go under 33F one time, so if I used LFP. I'd have to have a insulated box and heater to keep them above 40F where they have fewer charging restrictions

    In the winter, cloudy weather, I use a MANUAL start, 3Kw generator, and run 60 - 90 min a day to recharge.  2 gallons of diesel a week is generator running every day (rare)
    My winter load is generally 6,500 wh a day.  Summer is almost twice that when I am pumping irrigation water,

    I will never suggest a auto-start generator unless you are a fanatic and will keep up maintenance on it.  Forgetting oil changes will destroy your fancy auto-start just as fast as manual start.  But with auto-start being out of sight, out of mind, some critter will build a nest somewhere and cause a mess when it automatically starts next.

          Thank you, Mike. I never really thought about that. This is going to be our retirement home, so I will be either home all day for weeks at a time, or traveling for 1 or more weeks at a time. My brother and sister volunteered to keep an eye on things for us while we are gone.

    The best way is for them to invest in the first set of batteries,  once they have "skin in the game" they will keep a much closer eye on things.  And remember distilled water for batteries.
