Can I use an inverter to run fridge while travelling?

[DragonDriver]

Don't want to run fridge on propane while on the road ... don't want to check into an RV site just for an overnight stay.
I'm thinking it would be "easy" to replace my onboard converter with an inverter for the up to 8 hours we spend driving (and propane over night)
My back of the envelope figures tell me a bank of 4 LiPO4 100W should last for one day's travel.

Is it really going to be that "easy?"

You'll still need a converter to charge the batteries unless you get an inverter/charger which does both functions.

I think you mean 100AH for the batteries.

320-ish Watts is going to end up around 29A from the 12V system when you include inverter inefficiency and the control circuit draw. You’ll likely get less than 10A back from the tow vehicle. So I’d figure on a 20A draw while on the road, then 2A while overnighting. So 8*20 +16*2= 192AH consumed per day without allowing any power use for lights, TV or furnace at night. That assumes 24 hour refrigerator run time, which is worst case.

That’s probably not sustainable without recharging at least every other night.

In a word, yes.

It's a little bit more complicated than that, though. As was pointed out, you should do and inverter/charger. Xantrax makes an inexpensive one that is pretty good.

We added an inverter to run the fridge while driving. As stated it takes about 25A to run the fridge continuously. We have 2 100AH LiPO4 batteries. We also have 400W of solar. We can run the fridge while we're driving because the solar charges at about 15 to 20 amps while the fridge uses about 25A IF it's running continuously. When we get to our campsite, we switch the fridge to propane. This seems to work for a couple of days without any other charging.
