OK I'm part way there, space limits my plans to 240 amp hrs, Since it isnt a frequently recurring cost, I dont mind the extra for AGM, but with GC batteries, at 50% discharge they start to be degraded, so only 120 amphrs is actually usable. Is that the same with an AGM? Or can they better handle deeper discharge than GC? With both of us using Cpap and or Bipap I know we will be knocking down our available amps by 40 to 60 nightly with no other draws. Lights and other uses pulling it down even more so I am trying to figure the easiest way to recoup that using about 300 watts solar and genny time for the remainder without greatly shortening the life of the battery.
