rjxj,
You have forgotten about Peukert.
Nope. 135 ah down in 15 hours is only 9 amp average draw on 6 gc2. At worst it may be 14 to 15 amps when 2 items are on at the same time. Doesn't seem that it would cut the potential available amps in half but that is the general trend that I have noticed over the last 3 1/2 years.
Also not inverting to anything heavy. 5.x amp draw led television. 5.x amp furnace and 6.x amp frig. I would surely consider peulert more if I did use the 2000 inverter for big stuff as my toaster alone is 90 amps and the coffee maker hits 120!!! I tried a couple items on the old battery pack and didn't think it was the best approach for a group of sams club batteries.
There is something wrong with that set-up. Loose wire, who knows? It could even be the Trimetric. Is it programmed properly? Iis the shunt ok?
I get the expected 12.1 for "morning voltage" when down 300AH out of 600 and also with 200 down out of 410AH. I compare Trimetric AH down with voltage. Then on the recharge I note AH restored and it all comes out right for SOC. Lots of people have four or six batts and don't have that problem you are seeing.
I had a spell where it did not come out right and found an obscure wire lug connection that was too hot to touch. Fixed. So you have something going on that needs fixing, whatever it might be in your case.
