What is the power self-consumption of the SmartSolar 100/20 during zero sun?

Hello,

does the SmartSolar MPPT 100/20 with bluetooth consum any power, when the solar panel produces nothing? I am afraid, that the charger uses my batterypower for example in winter, when there is snow on the panels.

Greetings MP1254

Self consumption is in the datasheet - 25 mA at 12V, or 15 mA at 24V.

We have no idea what your setup is but the self consumption is minimal for most applications. In winter with a 40w panel on a dashboard I can end up in a situation where its running the battery down. Not exactly a normal case.
