I've had the PWD50+EPO for a few months now and have had the occasion to use it both short term and long term. The long term use was this past week in Lancaster, PA. I have the unit mounted in my electric bay after my older model Autoformer per Hughes's instruction. The unit functioned as I expected as did the app which proves real-time information.
I do want to relay my experience with one of my short-term trips. We camp at least once a month at our local county park. The park is in the midst of upgrading the electric infrastructure which has been in place since the 70's. Hours before our last trip to the county park sever thunderstorms rolled through the area knocking out power in the area and damaging one of the park's circuit breakers. I believe that's the correct name for the large green box. The local power company arrived after we did to replace the circuit breaker. The power in our half of the park had been stable but they advised that all power would be cut off for about 20 minutes while they made the final connections. No problem. When power returned about 25 minutes later things appeared normal for a while then our power went out. Only our power. Before I could check outside it came back on. After a minute or two it went out again. I checked the PWD and it was showing error code E4: Line Two Over-current. The PWD had determined that our amp rating had been exceeded and killed the power. This was an error I'd never experienced before. Whatever work the power company was doing had caused the park's circuit to not trip sending potentially damaging amps to my motorhome. Without the PWD50+EPO detecting the issue and shutting off the flow I never would have known. After a few minutes things stabilized and the PWD50 restarted and showed no further issues. While this issue probably wouldn't have caused any real damage to my motorhome given its short duration all it takes is one little blip to and the next thing you know you have to replace the microwave, the AC units and maybe even the residential fridge if you have one. The PWD50+EPO provides us peace of mind knowing that our electrical system is protected.
