Thank you for recommending the boost reconnect change, I have updated that parameter. In regards to LVD, are you saying that when the battery reaches 11.1v under load (well below 50% DOD), if the load was disconnected for 2-3 hours from that point, the true voltage would return to 12.0-12.3 (50% DOD)? I am aiming for longevity in cyclic life for this battery.
If you let your batteries get down to 11.1v even under a load you won't have to worry about them they will be dead in a very short time... 11.9 is pushing it... If they are that low I'd bet with no load for 2 to 3 hours you would be lucky if they got up to 12.0v
I'll bet your batteries are suffering now...

I lowered my LVD from 12.2 to 12.0 not 11.1. I didn't feel comfortable lowering it to 11.1 even with the admin's recommendation. I guess I should bump it back up to 12.2

it's up to you, any load reduces battery voltage, small loads and you may not notice it, big loads will therefore a small load removed won't have much battery voltage recovery but a big load would.
load testing is on method of testing batteries!

Do you have a Kill A Watt meter? If not you need to buy one..... You need to know for sure what your using.... If your using more than your system can produce you need to back off on your load or get a bigger solar system...
