It's often difficult to find the actual current inverters draw with no load. I have a number of them, so I did my own testing.
Inverter Idle Current
As it turns out, the RV we recently purchased, has the same model PROwatt SW2000 inverter I've been using 24/7/365 since 2012 with my solar setup on my home.
From what I've read online, a furnace typically draws 8-11 Amps when running. That's a lot, but a healthy battery bank shouldn't have had a problem overnight.
Might be time to have each of your batteries load tested. Here's what I've used: https://www.harborfreight.com/100-amp-612v-battery-load-tester-61747.html
Good luck!
