Here I demonstrate using a mobile power system to test and evaluate the scale of an off grid power system in an off grid environment. Using a Kill A Watt meter on a single incoming power cord to show power flow numbers off the inverter and a used fridge to test constant power drain. The fridge died four days into the test, which appears to be the result of the panels and batteries losing amperage in the high heat environment, the system never fully charged even though the amperage draw on the fridge was pretty low, I think it was a combination of losing efficiency due to heat, and the fridge not synching well with modified sine wave power. I would not be installing this exact system in the house, but having it both portable and modular on a cabin is the tool to determine if a system to be permanently installed will be equal to or greater than this in some way, like with the same capacity of panels but more battery, or if it could work with less battery or if it could use wind power to supplement production. I was also using this to test full-on construction site corded tools in the off grid environment on a real world jobsite, but those results just confirmed the results of prior testing, that this is just fine for running a regular small to middling size jobsite, with no generator usage.
