What is SCC MPPT State 1?

Hello,

I have connected the Victron Smart SCC (firmware version v3.13) via VE.Direct to a RPi running VenusOS. Via MQTT, I'm storing the data in a database.

So now and then, I see SCC State = 1. What does this mean? This status is not mapped to anything in the documentation, as you can see below:

I believe it's a kinda stand-by, with the MPPT off, panels being left in an open circuit state.

If it's in an installation with multiples MPPTs, those MPPT with state=1 aren't contributing to power generation, but when requested they will start producing.

Different than Off, when they will not respond to stimuli.

Just my 2 cents...
