Without doing a load test, I can't give an opinion on when they might fail
But it appears they have had an amazing life so far
It looks like the noco is doing the job
Not sure I would plan on them lasting the next ten months
I would get prepared to replace them , but keep using them as long as the can do the work needed
You want to try to stay away from full hookup campgrounds
You have your freezer to power and your machine (whatever it is)
You need reliable 120v power, I have solar and batteries, but it is a supplement, not my only power supply
Given an either~ or situation... generator wins.. hands down... add solar panels later..that's my opinion
That machine is apparently your additional income..lively hood..
Not just some hobby, which can wait if you can't use it.
Taking a chance that solar will meet your needs..is risky
