The only way I deal with hunting lodges and the like is to install close to full code (I do relax on the exact year, since it isn't new construction), or I supply parts and advice, and let them do it themselves.<br>
In Taos, we had some pretty poor folks trying to make it out in the desert, so I almost never turned anyone away, but not everyone got the benefits of a professional install.<br>
Try telling a fellow American living in a tent or plywood shanty that they have to comply with NEC 2011. <br>
Just to make you feel better: 12 v PV is one of the safest forms of electricity, so if the screw something up, they're not exactly going to vaporize the planet.<br>
They're much more likely to die in a car accident driving to your shop to get another fuse......<br>

I do see the benefit of the DC only for the fish houses, but the hunting shacks make me always think code. I have used the morningstar 300W for a few applications and have a magnum 1000W in my own fish house, so maybe I will look at that option. I'm sure the owners wont mind having AC available, and would make the code issues I see go away. That 1000w magnum of mine is a charger too, and thats a nice option to have. <br>
