You said you were getting a generator, so you will be doing some charging of batteries that way, most cpap units actually run on 12 volt dc, check your model and a 12 volt cord is likely available. Check your cord, if it has a "brick" in the cord it likely is a transformer. Mine uses less than 5 amps an hour, so 8 hrs = 40 amps, two 85 amphr batteries will only go down by about 25%. If you add even a small 200 watt solar package to get to a true topping off point, you can cut way back on genny use for charging.
Here is a sample kit for 320 watts'

Thanks for the info! My CPAP power cord doesn’t have a brick. The machine is 10 years old, not sure if that ha anything to do with it.
I will research a 12 volt DC option for it though. I didn’t think of that.
