Do you have led lights? If not, you could drain your battery pretty quickly just by leaving lights on.
Also, just having the fridge on propane still uses a little power. But it’s a constant power and would consume about 30% of my lead acid batteries power per day back when I had lead acids (assuming 80 amp hour battery).
One last thing. What do you mean when you say you had a solar panel hooked directly to the battery? I’m guessing you didn’t mean it this way, but you’re not hooking it to the battery without a charge controller, are you?
