Solar, just need to verify so you know whether or not master cut off also kills solar-again I wouldnt think so but easy enough to check
The referred to inverter is actually your converter, make sense now. Yep pretty standard..does not have an off/on switch, no real reason to. (earlier was referring to the solar panle controller). The distribution point (breaker/fuse box) should have a breaker for the converter BUT if working around it unplug camper.
So your either plugged in, or generator running, converter is also charger. Good to go.
..brings me to your other post concerning your generator. But that should remain in that thread so were not cross talking.
Nice thing about the HF meter-it doesnt hurt when you blow it up-just get another till you get a good one. Not all that accurate but for basic trouble shooting/ & learning to use, work fine. Have fun
