Need enough power to keep Frig working in storage
So we have a 2015 Georgetown 364TS with the big Frigidaire residential frig. We usually go out every other weekend but are not suppose to leave our unit in the driveway per homeowners restrictions, so we normally keep it in a gravel lot a couple of miles down the street, but it has no power hookups and emptying that frig is a major hassle for only a week or so and we would basically need extra frig close to the same size for the stuff since our house frig won't accommodate it and that includes our extra frig in the garage as it is, not to mention remembering to empty 2 ice makers.
I found a covered storage place that let's you plug into 20amp service the power cycles and you only get 2 hours of juice per 24 hours.
So my question is this: is 2 hours of electricity per day enough to keep the battery bank sufficiently charged to power only the frig? And if there is a negative drain how long would the batteries last before dead? How do I make these calculations? My thinking is even if 2 hours is enough for a full charge, starting with fully charged batteries, if I had to run over once a week and fire up the unit or generator for an hour to give the batteries a better charge, would that be enough to keep the frig going? Thanks for any assistance.
Also, suppose a solar set up would fix my needs at the current storage lot, but have no idea how to research that and would need to consult with a solar expect.
