The winter is coming.
My system is rather small and hangs somewhere that is never heated and rarely occupied when it's cold.
It tend to be below freezing for months here, with occasional drop to -30*C range.
As far as i know, it's not good for the cells to be charged under such conditions. Really not good.
So how people solve this problem, assuming the solar panels are the only power source?
I was thinking of wrapping the packs into something insulating and non-flammable, with heaters inside connected at the solar side. Give or take temperature-controlled charge off switch.
This way the cells would be warmed first, and then start charging if there is enough sun left.
However, that makes me worry about overheating the cells, and i'm not too sure it's going to be enough - temperature sensor is no deeper than the surface of the cell, and the innards might stay frozen, no?
