I can't give you a technical answer, but after our Parallax Power Center went out, I found that the polarity on the outdoor outlet we use was reversed. The repairman said that it wouldn't cause problems with normal lights, weedwhackers, etc. (and it hadn't), but he warned that reversed polarity will cause problems with modern electronics.
Did it cause our problem? Don't know. I had been using the outlet regularly for over a year to keep the fridge going and the batteries charged between outings. So if it did pose a problem, it wasn't immediate. But, our rig is simple. Your's being new, it undoubtedly has higher technology. You may have saved yourself a bundle.
