Just curious on what everyone is using for batteries. The dealer installed 2 Exide Deep Cycle 12v's and I'm thinking it's not enough. We are heading south in a few days and I'm worried about my refrigerator going 3 days on the inverter without getting a charge. The charge wire is hooked up on the TV but I'm a little bit worried. Back in July we overnighted in a truck stop and woke up to the lo voltage alarm on the inverter panel. Not sure if it was a fluke or not. Both batteries load tested fine.

If you want three days, get a generator. I have 4 27 series batteries and go comfortably for about 12 hours.

Two batteries of any size, will not feed an inverter very long if there is any draw at all. You need at least 4 large deep cycle batteries or a generator.
Don't know what your frig draws, but it will use a lot of 12vdc inverted to 110vac.
I have 600 watts of solar, so I need a lot of batteries [5 x 125 amp hr bats] to store juice for a 5,000 watt inverter to feed a microwave, A/C or fridg.
