PWD50-EPO-H not working I bought a PWD50-EPO-H and installed it correctly in my 2023 Airstream. When plugged into a 110 outlet in my storage area, I get a E6 error message. E6 is "Line Two Neutral Reversed" - it isn't wired wrong. I checked the electrical outlet and it is wired correctly. I tried two different 110 to 50 Amp connection adapters, one new and one I've used and had for 10 years. I have called Hughes 5 times, and noone ever answers. I have left a message, three days later no returned call. Apparently they have NO technical support. I am super disappointed, and can't use my RV. Update.............. 5/2/2023 After posting this review, Hughes called several times and were very nice. As it turns out, after leaving my RV plugged in for about eight minutes and the WatchDog resetting 2 or 3 times, the error magically disappeared, without me making any wiring changes. I then unplugged and replugged in the RV several times, and still no errors. I pray it stays this way forever. I am looking forward to the Bluetooth connectivity. Being optomistic here.

Intermittent False Errors and Poor Product QA/QC It worked well for the first day then it started giving error codes E7 or E1. I thought I had an electrical problem at first, but then realized that a slight movement of the surge protector fixed it. I’ve done it several times so I’m certain there is a defect inside the surge protector. It also doesn’t wait the 90 seconds like it is supposed to. Just lightly tap or move the protector and the error immediately goes away.

Tired of low voltage or power spikes, try this I got tired of low voltage damage to my RV components. The last time I replaced the refrigerator circuit board, I got the Hughes 30a autoformer. I haven't had a surge or low voltage problem since. It works flawlessly without constant monitoring. THANKS HUGHES!

I purchased this unit 2 years ago and… I purchased this unit 2 years ago and it was in use a total of 10 months ,it is completely dead now ,not sure that it really made any kind of a difference to my RV ‘s electrical performance at all,

I purchased an autoformer… I purchased an autoformer transformer/voltage booster after having low incoming voltage on my 45’ Holiday Rambler Navigator. Before installing the autuformer the Navigator would shut the power off because the voltage at the park was too low. Problem solved and now I would not want to be without the security of knowing that the Incoming power Is correct. Great investment for peace of mind.
