Fighting the South Florida heat!. I find myself solely relying on my solar system for weeks at a time. My system is a 24v system (components listed below) the battery bank was with 8 - 100 amp Battleborn batteries. My batteries would go from 100% charged at say 10pm and by 6am they would be down to 18-20% and the volts would drop low enough to shut they system down with a low battery alarm. (Just as the sun would start coming up) (yes, I am attempting to run 2 ac units to keep the 45 ft RV somewhat cool)
I figured adding a few more batteries would get me the extra time needed for the solar panels to start charging the batteries again. I added 2 more batteries, wired them in 2 seperate 12v strings of 5 batteries wired in parallel and then connected to the other string of 5 in Series to get the 24 volts needed. I was thinking that would be 1000 amp hrs.? (Which is what I changed the battery settings in my smartshunt too)

Now it seems I have plenty of battery life in the morning about 50% but my volts are now dropping off by morning enough for the multi-plus's to shut off with a low battery alarm.
I am hoping that I'm just not understanding something (or a lot) and I have a setting, or two, or three wrong.
Any educated assistance would be greatly appreciated I would also love to find someone on the southeast coast of Florida who could look at the system.
