Battery Life in Hours
Our new Mobile Suites came equipped with two 6 volt batteries and a 1000 watt inverter. We spent one night dry camping at a casino and during the night an alarm went off and it was discovered the bat...

I got kicked at the casino, but that's beside the point. It is a 20 cu ft fridge and if I read right is supposed to draw on 5 amps. The furnace was on and water heater on propane.

The batteries should have been fully charged, if I read the panel correctly, as this was our 3rd night of use since purchase and the prior 2 were connected to 50A.

thats 5a at 120v aka 600w
thats 50a at 12v from the batteries into the inverter to make 5a 120v out to the fridge
this power conversion confusion has come up a lot lately
general rule, if ts 120v multiply amps by '10' to get DC battery amps used by the inverter
we had another thread recently new RV residential fridge on inverter, drawing 45 amps
same thing, his was listed at 6a 120v aka 720w,
inverter use was 540w to power fridge aka 45 amps
he was using less than the listed power (which is usually the Max limit)
but its quite a shocker when you think that is 5a battery power and find out its NOT
