I don't have a SMA inverter in the system... After I took this picture I reset the Classic 150 to the factory defaults and re-programmed it, but why did it show SMA? I could not find any documentation that explains this.
Ahhhh... I guess it must have gotten into SMA communications mode ?
Go into the MISC menu and then the COMM sub-menu. There should be a selection in there
to select SMA and non SMA mode. I can't remember what the other mode is called.
But as long as the charge stages happen when they are supposed to, it shouldn't matter.
I can't remember exactly why this shows up though except that the SMA Sunny Island can tell the Classics when to go to Float etc.

Ahh.. With the clue above I found it. In an older manual revG 2056. It's not in the newer manual "Firmware 2193" Thanks boB.
