Title: Why does my 150 show "SMA" on the display?
Post by: FredB on July 22, 2023, 05:37:58 PM
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.
