It's Alive! Somewhat. One panel not reporting in, but looks like the power optimizer wasn't connected. Easy thing to miss in the cold. Will have to get out there when it warms up in a day or two. There's also a slight covering of snow still remaining after roof-raking the array last night. Very happy I went with ground mounting.
Thanks again to #TruNorthSolar for their hard work. (I don't believe they're on the fediverse yet.)
