1) Only if your Solarpanel temperature goes not under -30C.


2) The BlueSolar MPPT 100/20 support only 330W in a 12V System. If it is ok for you to loose 70W, then yes, it will work. otherwise the BlueSolar MPPT 100/30 is more suitable, exspecially if it is winter and you get full sunshine because the panels can deliver more then the rated output.

Also interested in this - will to much panel output break the MPPT or will MPPT just limit the power but otherwise work normally?

Is there some upper limit for over power? Is for example 2000W for MPPT 150/70 still safe? I'm thinking it for outside summer season when yield is quite low here.
