There's plenty of Gen 2 HPWC installed as Destionation Chargers that are out exposed to all the elements, including the sun - it doesn't seem to be a problem. Gen 3 are a bit newer of course, but I wouldn't expect any difficulties - they're not supposed to get hot if they're operating correctly.Anyone got experience with installing these in the sun? Do they get too hot in summer if you do or is it a non issue?
