From what SMA has said, I think your Canadian model inverter is a lot
more cold temperature capable than the ones they sell in the US. I
tried, buy was unsuccessful in getting a Canadian model a while back.

Dan with Exeltech just gave some good insight to cold weather inverter
capacitor tolerances in the thread "Electrolytic Caps vs. Thin Film
Capsū". <br><br>
We had -26C here (Edmonton) today and the next couple of days are looking
like minimum -30C with windchill on top of that. This is pretty
typical at least a few times a winter season.<br><br>
I have one install, circa 2006, with two SMA's outside and have no
issues. <br><br>
I know that Enphase and SUNERGY PV Inverters are rated to -40C, but no
others come to mind. I would stick to the manufacturers that spec
their equipment for -40C.<br><br>
