HI Eric, Sounds like the "stop absorb" might have been enabled. This will stop the AGS when the battery volts reach absorb setpoint.
But has no impact if starting the generator manually. jay peltz power > Sounds like you talked to the right guy, that's his info...except that he > has, according to what he told me, an SW not an XW.
