To: "Wrenches" <[email protected]> Date: Monday, January 16, 2012, 7:47 PM Jessie, Dan with Exeltech just gave some good insight to cold weather inverter capacitor tolerances in the thread "Electrolytic Caps vs. Thin Film Caps". 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. < div>bundling up for the cold...benn DayStar Renewable Energy Inc.
