newbie trying to understand MT50
I have an MT50 digital control for my 40 amp commander controller. Recently I had the entire solar system off with battery out. After turning it back on(yes plugged charge controller in first) and...

I'd expect a solar panel in a garage on a sunny day with door open to put out a few volts. I can get 10.5v from mine parked under a streetlight.
The panel does not have to be in full direct sun to produce voltage, and might even produce near its max voltage in cloudy skies, it will howevernot come close to producing its short circuit current unless cold and in direct sun.
The MT50 to my knowledge does a lot of inferring as to battery state of charge, by guessing after looking at voltage. it is not a real battery monitor so take its readings as to battery state of charge,with a huge grain of salt and more than a little skepitism.
I have a Shunted battery monitor and completely disregard the battery % remaining screen, and only trust the Ah from full screen if I have recently reset it when I have verified full charge by other methods.
