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.

Jessie,
Dan with Exeltech just gave some good insight to
cold weather inverter capacitor tolerances in
the thread "Electrolytic Caps vs. Thin Film Capsþ".
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.
I have one install, circa 2006, with two SMA's outside and have no issues.
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.

last time I checked, and when I called they
