<p class="MsoNormal">I just figured out why I could not reset a GFI error on one
of my micro-inverters. First, I noticed condensation in the led lens, then water
literally dripped out of the AC side as soon as I disconnected it. This was
mounted on the top backside of a panel, roughly two ft above a flat roof. \u2026..
