Progressive Industries Portable Electrical Management Systems (EMS) provide full RV protection against all adverse power conditions. You will feel secure with multi-mode surge, voltage, polarity and lost/open neutral protection. Each unit includes a digital display, scrolling continuously through the power source information: Voltage(s), current, frequency, error code, and previous error code (if applicable). Replacement parts are simply plug-and-play, making repairs quick and easy. As with our portable models, the computer is driven by state of the art microprocessors. Should the software ever change, EMS owners can receive a free upgrade at no cost.

It took me a while to decide whether to purchase the portable (EMS-PT30C) or hard-wired unit. Obviously, the portable unit is completely portable and can be used on any RV. Also, no installation is required--you can be up and protected in only seconds. However, potential theft and convenience of use swayed me to go with the hard-wired unit. The hard-wired unit is theft-proof (assuming you install it inside your RV). The remote display (only available with the remote version of the hard-wired unit) displays realtime, voltage, current draw, line frequency, and error history (current and one previous event) in the comfort of your RV. The hard-wired version without the remote display does display the same information, but it can only be viewed on the EMS unit itself.
Installation instructions are helpful, clear and also include a few pictures to clarify some of the steps. Assuming you have easy access to the incoming AC in your RV and sufficient space nearby to place the EMS unit, then the installation should be fairly straighforward. If not, then the installation could be much more of a challenge.
For those that may use a generator with this EMS, chances are your generator has a floating ground (most newer inverter generators made by Honda, Yamaha, etc. have floating grounds). The EMS will return an E2, open ground, error. The EMS will not allow any power to your RV with this error. You have two options to correct this situation. One, you can turn OFF EMS protection (via a switch located on the remote display) and operate your generator with no EMS protection. Or, two, you can insert a "bonding" plug (bonds the generator's ground & neutral together) in one of the generator's 110 volt outlets so you can operate your generator without having to turn off all EMS protection. The bonding plug is somewhat controversial. I'd suggest googling the pros and cons of doing so beforehand so you can make an informed and safe decision.
Lastly, just want to mention that a lot of folks assume they're protected from all electrical gremlins by using a "simple" surge protector that typically costs $75-$125. Not true! A "simple" surge protector only offers protection from "momentary" (less than a second) voltage spikes resulting from lightening, nearby switches, or appliances. A "simple" surge protector offers absolutely NO (zero) protection against "continuous" over/under-voltage situations and/or serious wiring problems one may encounter in many RV parks. Only the more expensive Progressive Industries EMS (Electrical Management System) provides this nearly "complete" electrical protection (in addition to "simple" surge protection) for your RV.
I thought I might have issues with it protecting from the generator due to a couple of reviews on here, but I was more worried about surges from shore stations than my generator.
Anyway it works fine with my generator and detailed instructions for use with a generator or external source or both is included.
I did not put the wired remote in the interior - I kept it in the bay. Who needs a bright cycling light flashing at all times?
Installation was straightforward as far as what to do - doing it was more challenging than I thought. When other reviewers mention the difficulty of working with the wires they are not kidding, so have your RV guys do it if you don't feel like grumbling a bit.
I have used it 8+ hours on the generator Onan Marquis Gold 5500 without issue and had it hooked to both a 50amp and 30amp (with adapter) power station. No issues or cut-offs, but if there's any errors it gives you codes to troubleshoot.
Last year I had a microwave "pop" and die at a park, so I got this guy because while they're a bit pricey - they're not as bad as these appliances, as you probably know.
It is all that it is advertised to be.
It works well.
The install takes some patience to get the #6 wires cut to the right length and then bent to line up with the lugs.
But, that is no fault of the device, it's just the way it is.
I put the remote display upstairs in my 5th wheel RV.
It's nice to have the information available to me so that I can monitor what electrical devices and appliances I'm using and then make sure I do not trip a circuit breaker or overload the GenSet.
