We are brand new Ollie II owners and our maiden voyage was to the Oliver Rally a week ago! We have the most beefed up battery package our $$$ could buy, expecting to boondock frequently. All went well with full hookups at Lake Guntersville and we are making our way home via some Harvest Hosts without hookups. Two times our batteries have been depleted in the middle of the night, without AC, fridge or water pump on. We do charge our phones, run the fan on low, and run CPAP machines while sleeping. Surely these would not draw the batteries down to zero in the middle of the night, right? This morning, after a couple hours of sunshine, The Lithium App says both of our batteries are at 11% each but the Solar Charge Controller says our batteries are charged to 75%! and 12.7V
Any usage of electricity sends the controller back into the RED and flashing! 😱
Again, we are newbies so how might we be draining our batteries so quickly?
