While I agree Shadow Catcher has the best low cost solution but, can also tell you the following.
An "INVERTER - WITH HEAT PUMP would work from -5 to 118F heating and cooling. It could run on a pure sine 1000 watt honda generator & a 1,000 watt PSW morning star inverter and it can effectively heat or cool an area as small as 100 cubic feet. 5 X 6 x 3ft . It can be operated with a few solar panels and my system on a 7 x 18 trailer averages 165 watts @85F exterior cooling the interior to 72F. At 100 F exterior it climbs to about 250 watts per hour.
So there are many other factors to consider, shadow catchers system is great cooling only between 75-100F. The mini split does heating & cooling -5F to 115F using very little energy.
