More info on the solar fires:
Amazon has joined in, blame is being placed on an Amphenol connector:

Apparently microscopic cracks formed in the plastic housing of the weatherproof connector, allowing water inside and causing a corroded/high voltage drop connection.

Weird, as Amphenol is a pretty well respected company. I use their stuff in all my hobby projects over the no-name Chinese stuff.
