Yep, if everything is working off shore power it means the converter is doing what it's supposed to do. Now remember, when you unplug the shore power.. the micorwave, air conditioner will not work. Unless the Television is 12 volt it will not work either. none of the 110 volt plugin's will work either, once unplugged to shore power. Most everything else will work... like the fan on the heater, etc. but go too long without shore power and caputt goes the charge on the battery.
So even if the fridge is running off propane down the road I still have to have the batteries? Ok so since I am connected to shore power at my house now and everything is working then it's safe to assume to converter is working then right?
