Took a small refrigerator I had in the garage to see if it would work out, first night the batteries went low and didn’t have enough juice to make coffee in the morning and the inverter turned off, the second day I ran it on high all day then turned it down at about 4:30 pm to a medium setting and in the morning that saved enough electricity to run the coffee maker, I plan to add another battery pack or two for a buffer, when the furniture goes in it will include a 110v washer/dryer and a full sized refrigerator, had some good meals on the treager, it was cold most of the trip with a couple days of severe storms and wind, mostly at night, was surprised that the solar kept up, but it did. In all I feel like I got a lot done and it feels good to be finally doing the finish work. Next trip I think I can finish the walls. But there is still trim, painting the ceiling boards white, then staining the walls and 3 coats of varnish to make it pop and easy to keep clean, when all the boards are on. Next trip in two weeks.
