Op said "Just wondering if this is a possible solution to running a generator, it may not run the A/C very long but up here we can get by without that and the microwave, and run the fridge on propane, just need the lights and electronics pumps, fans and maybe some music for a 3 day weekend. perhaps the tv for a movie on a rainy day." For what you are looking to do 2 6v GC batteries will be more than enough for a 3-day weekend. There is no need for Li batteries or these expensive portable units. I camp for a week like what you described, and my 230 AH batteries are at 50% SOC without any genset recharging. This has been an interesting thread with a lot of good information because many on here have greater energy requirements than you do. For what you are looking to do 2 6V Sam's Club golf cart batteries for about $200 will be a lot cheaper than these portable Li units with a lot less AH's.
