What would cause the furnace from turning on

We have a brand new CC Cottage 40CRS and have done a few overnight dry runs so far. Were having problems with the furnace and could use some help.

Right now were using 120-volt connection on a temporary 2,400-watt inverter and the onboard propane. During the day when running the generator everything works fine.

Ill run the generator to say midnight. Ill set the furnace to come on at 60-degrees. On one night it did just that and everything was fine. The next night, same scenario, the furnace never kick on and it was 44-degrees when we woke up.

How likely is it not working because its relying on the battery or could it be something else?

Assuming you have just one battery ... a furnace blower fan will suck a fully charged battery down overnight. I'd check your battery voltage as your converter isn't a real robust charger on its own. Your furnace is 12 VDC controlled and may not have enough voltage left to run it.

Did you check to see if you're out of propane?
