I just got off the phone with Gemini and the nice lady couldn't find the outdoor rating for their XT series.
She said she thinks it's roughly 5-7 years but couldn't produce any document.
I'm assuming it's a different rating for different colors.
I have a customer that wants to put a tag on the generators he installs with his service info but I have no idea how long they will last for him.

Does anyone have a document with the outdoor rating?
