Just curious how is MPPT charger controller like a Victron powered?
Is it powered by just PV input? or combination of PV and battery? I mean when there is no or little sun, will it still be able keep the blue tooth running so we can check the status?

Thanks
 
It's a mix. Some SCC will come to life with only solar panels and sunshine. Others require battery power to start. Once running most will work off solar alone, but some go completely nuts on their battery / load output and this can kill sensitive electronics that the charger may be powering.

They will all run off battery alone. As long as you have battery power your bluetooth comms should remain working.

Victron is one of the devices that will perform 100% safely and correctly off solar alone. Battery or solar or both, you will have working comms with your Victron SCC.
