SSP-30X

Good quality and good indicator lights.

I hardwired this into the bottom of a cabinet near where the power cord comes into the RV. I then put the display up at high level where I can see it even from across the camper while sitting or standing. It works absolutely great at both protecting the camper and providing information on power usage and reliability. It has helped me to know how much power each of our appliances and devices take, which has proven to be incredibly helpful when running the air conditioner and close to the maximum of a 30 amp site. One added tidbit that I will share is that I took the time in trouble to install this using two 30 amp locking plugs so that if the unit ever fails, I can simply bypass it by unplugging the male on one end and the female on the other from the unit and then connecting those two together to bypass this device. It cost me a little bit more money to buy those plugs and the time to do that, but I realized if this device ever failed when I was on a trip and it prevented me from using the RV, I would want to be able to bypass it. This allows me to do that very quickly and very easily.

I bought the EMS-HW50C to wire into my 5th wheel trailer. I also have a 7kw Onan generator. I wanted this to monitor both pedestal and generator power. This requires it be mounted after my transfer switch but before the panel. My transfer switch is located inside a tiny space after crawling deep into the storage bay. I could’nt even fit my shoulders in there much less get the transfer switch apart and wire this EMS in. My only option was to pull out the main panel that is mounted inside a cabinet in the bathroom and remove the 6 3 wire cable from the Main panel and extend it to a shelf directly above the cabinet. This required some butt splices with screw terminals on either end be installed inside a plastic box and taped off to prevent shorts and was mounted inside the main panel cabinet and extended up to a high shelfdirectlyb above the main panel cabinet. This EMS was then mounted up there and wired and a return 6 /3 cable with ground was returned back down through the shelf and into the cabinet and wired back up to the main panel. The cable, connectors, romex clamps, tape, and various cable grommets, etc, amounted to a further 97 dollars and about 10 hours to install not including travel and buying time. It was not a hard job but required some tight work inside the cabinet that housed the main panel. All else was straight forward. The directions were fairly clear with the exception of the arrow on the coils around the output leads. I couldn't find any arrows. It turns out that both coils are sealed with black RTV and the stamped arrows were obscured by smeared RTV during assembly. Luckily, it was mentioned by another installer on the same unit on youtube, otherwise I would have to placed a call to Progressive. The unit works as described, however, the current reading is way over reading amp draw by a factor of double on both phases of power as verified by my own clamp on amp meter. I’ll call them tomorrow regarding this issue. My working on this unit leaves me somewhat concerned about the actual engineering of this unit. Its not hard to determine actual amp draw and the fact thats it’s not even close, is disturbing. I also have questions regarding the stand alone readout. The cable attaches to the bottom of the readout rather then the back, meaning the data cable is always seen after mounting. Why? This also screams of poor engineering or just carelessness. If you are concerned about the appearance of your installation and of those who can’t run the connection from behind the readout, offer both input cable locations so the final finished appearance is preserved. I celebrate well engineered products and abhor poorly executed ones. This has all the earmarks of a typical offshore made product despite its being engineered here, but, this is just my opinion. I’ll know more after I call progressive. UPDATE 2/24/2020. I called Progressive Industries and talked to Brad in tech support. After telling of my over amp reading. He immediately offered two options. Send the whole unit back for a new one or replace the logic board and coils. Our conversation confirmed their concern for their product and without hesitation offered two solutions. Send the whole unit back or install a new logic board and coils. I opted for a new board and coils. I’m impressed with their customer service. The new board and coils should be here in about a week. He also said that the reading on amps is courtesy and would not affect the performance of the HW50C but also agreed that something is wrong and should be fixed. Thank you Brad and Progressive industries. 2nd update: 3/29/20. I finally received my new logic board and new coils. Some snafu in shipping at progressive. I removed the coils and circuit board and replaced them. The amp reading is better then before but still off some from my clamp on readings but close enough to call it good. That was easy. I also remounted the unit after my first trip out. It does hum some because of the relay and had it hard screwed down to the shelf in the bathroom. It was just too noisy at night. I bought 4 rubber donuts about an inch across and 1/2 inch high and 4 rubber covered washers and screwed it down again. Ah, the sound of silence. You might want to keep that in mind depending on mounting location.

Installed the inline surge protector yesterday so I don not have a long term review but the item looks well made and I will update if I see nay issues. I like the remote screen as I mounted it in the RV side storage compartment where the incoming power entered the RV behind a side panel and put the screen on the panel in the compartment. When I plugged it in I heard the engagement click and seen the voltage, hertz, amperage and E0 (clear - no codes). When I added a load, it showed up on the screen and there were no issues. My biggest issue was the room I had to install, but it came out well. I think this is better than one you place on the cord.

Product works fine but screws to attach hinged cover are missing. Package was sealed do I assume this is a packaging issue from the manufacturer. From the other reviews it looks like trying to contact support to get the missing screws is unlikely, so I will just find something in my scrounge bin to do the job.

Very good product at the dollar point value. Easy to use and tests all that you need to know about a 50 amp electrical RV service

Seems to work perfectly. There is a ring for installing a padlock in the cord. The weatherproof box is good quality. Hopefully it will protect us from a voltage surge.

I PURCHASED THIS PRODUCT BASED ON REVIEWS OF OTHER PURCHASERS! IT'S THE "PEACE OF MIND" KNOWING MY BRAND NEW 5TH WHEEL IS GOING TO BE PROTECTED FROM SURGES AND POWER SPIKES! TRIED IT OUT TODAY, PASSED! JUST HAD A NEW RV ELECTRICAL PANEL INSTALLED- ELECTRICAL FOR RV WAS CORRECTLY WIRED! I WILL BE PURCHASING THE 30 AMP SURGE PROTECTOR AS WELL! GREAT PRODUCT, SO FAR!

My original unit failed after 18 years, lifetime warranty but only for the original purchaser which I was not. This one was wired identically and was an easy replacement. Works well so far.
