I have a similar set-up (at 400a/h LFP and 660w) and get the temptation but in the vagaries of the real world harvest, not too sure it’ll always pencil out -
In theory something like this: a gallon of propane has about 91,400 BTU’s, while 325w (ac power) at say a more conservative 75% duty cycle (considering local and inverter losses…) would equal 5850w over 24hrs equals 15.6 hrs refer operation per gallon of propane or 78 hrs per 5 gal tank…Just saying…

Im not sure what your trying to say, but my fridge in my camper is a old one where the burner stays on all the time and I can easily let it go 3 months running 24/7 on a single 5 gal tank. once I start it up in the spring it stays going all summer until I winterize it in the fall, so three years now it has done this. I do this with my 5th wheel also and same thing, I fill my bottles in the spring and they don't get filled untill winter when I am doing inclimate camping. the 5th wheel does have a DSI large fridge, but it has 7lb bottles.
Well, in retrospect it does seem oddly high but was only a rapid back of the napkin calc..
However, I believe converting BTU’s into watts is the proper way to draw conclusions…
