I totally agree designing a solar system with ample PV and a balanced amount of batteries is the best way to proceed however, two weeks of clouds in mountainoussnow Country - South Central Idaho and you need a generator. I only ran six hours on mine last winter & 15 hours total for 12 months of the prior year but finding a decent water cooled 1800 RPM propane generator has become more and more difficult. personally I have a 20 KW that came out of mine in Colorado many years ago and continues to function perfectly.
