Progressive Industries warranty void if using a Yamaha EF2000iS

Found this today: https://www.progressiveindustries.net/disclaimer

"Please be advised the Yamaha Generator Model EF2000iS does not generate enough start-up current which causes the unit to overload. The generator then puts out non-true Sine Wave power. Progressive Industries units are designed to operate only on True Sine Wave power.
For this reason, The Progressive Industries Warranty is hereby void if an EMS Unit is used in conjunction with a Yamaha Generator Model EF2000iS. Any damage sustained to the EMS unit are the sole responsibility of the customer."


I wonder how this might apply to other 2000 watt generators that boast using the Yamaha engine?

Why would it be necessary to use an EMS with a generator? Are they to protect against line power surges and faulty campground electricity?

Excellent point for the portable EMS units, I have the hardwired EMS.

.

I wonder if this happens to any other inverter generators?

The same for any inveter of any wattage of any brand , like Honda.
Couple things: if you are using a quality generator/inveter like Honda or Yamaha there is no need for your power protection like Progessive ( note I own their product and two Honda 2000i but not used together. I tried that and the PMS freaked out). I contacted progressive
and they said don’t do that , just like their documentation stated. PMS explained to me one, no need for their unit using a Yamaha and Honda their power is very clean. Second they said the Yamaha and Honda inverters use a ‘floating ground’ which the PMs
Logically assumes you have a power issue. Just repeating what they told me and my experiences.

The quality of AC output from an inverter generator is as good as you can get. Lewster advised me to always use a neutral-ground jumper plug directly plug into a socket on the genny. All RVs are wired with a floating neutral because the source at the pole is already connected and if the RV was then plugged in with reverse polarity you would have a mess on your hands. It might even be lethal.

Missing info - " start up current " is meaningless !
Whats starting - what , and how much current are they talking about - with this statement ?
I agree that using there device with a generator should not be inline with the generator .
If you are using a grid-tie inverter , then having the EMS plugged into the gird / shore-power to an inverter that has a transfer-switch , that is designed for generator backup .

My Progressive EMS manual from fall of 2016 said don't use with any inverter generator.

Make a Plug for the floating ground

Lots of good Youtube video instructions on making you own plug to stop any floating ground issues. I made two of them for my two Honda 2000! I just tried them with my Surge Guard and the Micro Air installed on the AC. I had no issues running the AC with only 1 Honda, I had no fault codes or circuit issues.

Greetings. Iím confused on this one. The manual for my Progressive ems hw30-c makes no mention of generator usage in the warranty. I have it hardwired in to protect the entire trailer electrical system. Iím still working on this forever project but was definitely planning on using a Honda 2200 for boondocking. One would think the ems should be one of the most robust pieces in the loop and if it didnít like the input voltage, it just would not let it in. I did call Randy at Best Convertor today and he said that there are no issues with using my ems with a generator.

Steve read this article, I think it will clear things up for you.

http://noshockzone.org/generator-gro...utral-bonding/

I made one of these plugs for my Champion 3500 generator just so I could see how many amps my trailer was using with my Progressive EMS-50PTX. With a hardwired EMS I believe you will need a neutral-ground bonding plug so your generator and EMS will play nice with each other.

Micro-Air sells these plugs if you don't want to make your own.
