With 1 AC running with the Fan the on High it is pulling right about 75amps at 12volts, with the fan on low it pulls around 60amps at 12 volts. I installed all the batteries over the weekend and I ran the AC from 4:00pm to 9:00pm and then switch it fan only which draws about 20amps and I turned that off this morning at 7:00am. When I checked the batteries this morning they were sitting at 12.1volts. I was looking to have enough power to run the AC for a few hours after the sun went down to cool the RV down enough to get a good nights sleep and keep the fan running all night for the white noise effect. The wife and kids like to keep it cool. According to my Amp hour meter I used 696amp hours. This was from 4:00pm to 7:00am the next day and during that time I was able to generate 147amp hours of solar power, since it later in the day when I started the test. It definitely put the batteries to the test, and so far I am very happy with results. As the weather cools down, I will not be running the AC, but just the fan and that should not tax the batteries as much. It is nice to be able to finally be able not to have to hook into shore power or fire up the generator. You guys have been very helpful and I will keep you posted as time goes on.
