Amp-Hours and Appliances
People living in off grid tiny homes and vans often use propane or butane as a cooking fuel and sometimes to heat enclosed spaces, even if they have a solar power arrangement. The impression is that electric cooking appliances put an excessive strain on off grid solar power systems and drain batteries excessively. The same could be said of electrical off grid air conditioning systems. So let's do some calculations to determine if it is theoretically possible to power cooking, heating and cooling appliances with solar and/or batteries. My background is in electrical engineering and physics. Physicists often start analyzing a system from the point of view of energy. Most natural physical systems are in a state of minimum stable energy configuration or are in the process of reaching a minimum stable energy configuration. So let's analyze the off grid system from the point of view of energy. Since every system interacts with it's surroundings, energy is often changing, whethe
