We don't much like bees.
Well, at least I'm not too fond of them as I'm allergic, but that's kind of besides the point here.
Our problem as a company with them, and many other insect critters, is they like to try and get into warm, dry places. Places such as inverters, which at 40 degrees are pretty much a 5 star hotel in the insect world. You can't blame them for wanting a bit of luxury now can you?
Jokes aside, it's not a common problem, but if you do see them trying to make a nest in your inverter please give them their marching orders ASAP! This little bit of honey caused a burnout which cost $250 to fix according to the sparky who worked on it. And as for the bee, well, he claimed he couldn't find his wallet. Very uncouth of him.
