Battery Bank Usage

So far, we been doing really well on the battery system. We have 3 85 amp hour deep cycle marine batteries. Which means we have an effective battery bank of 127.5 amp hours. For those doing the math, it is 85 x 3 batteries x 50% = 127.5. The 50% is how low you can discharge the deep cycle battery without hurting it.

So far running the everything we haven't had an issue with bank. We had a similar bank in the 5th Wheel and it didn't seem to do as well. We believe there must of been a drain somewhere in the system.

Right now we seem to be able to run the following (within reason of course) without issue.

  • Toaster Oven at Night for a about 40 min
  • TV for 4 or 5 hours at night
  • Speaker system at night
  • Mini Fridge and Freezer Overnight.
  • Laptops during the day.
  • Hair Dryer during the day.

In General during the day, with the panels, we pretty much have no issues. We have to see how that changes when it is really cloudy. It is primarily at night that worries us, but so far even with some usage, we have only had to use the generator once and that's when used the crockpot and toaster oven for a long time. Even then I'm wondering if we could have made it through the night without running it.
