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?
