Yamaha 2K did not work with EasyStart

[lsbrodsky]

The other thread is 15 pages long so I am starting fresh. I finally got around to testing my EasyStart woth my Yamaha 2K generator:FAILURE.
First I started with my Progressive surge protector in the circuit and it was tripping out on undervoltage so I connected the generator directly to the shorepower cord. The generator tripped on Overload when the compressor tried to start. After a minute or two the AC power would reenergize.

The frustrating part is that I just installed a bunch of Victron electrics and tried my inverter in hybrid mode with the shore limiter set to 18 amps. I watched the inverter pick up the slack when the compressor started, it did start on the inverter. But the generator still tripped off on Overload.
My generator is propane and the only thing that I can think to try is the load screw on the regulator, which I may try when I am next camping. But my generator is rarely under any load since battery charging does not take much effort. It runs just fine charging the batteries.

I cannot easily measure the air conditioner start amps to see if the Easy Start is working properly, although the compressor starts are much quieter. But since the generator still tripped off in hybrid mode, I am wondering if there is something squirrely about the Yamaha generator. Any experience out there other than the single hearsay report by Matteo?

What altitude are you at?

[Mollysdad]

I wondered what A/C you're using? 15 or 13,500?
Also I think you said you're on propane, does the Yamaha power the A/C on gas?

[lsbrodsky]

I am at sea level, my A/C is 15k, and I have never put gas in my Yamaha.

Larry,

The EF2000 is rated at 13.3/16.7 amps steady state/max at 110V. If you set the Victron at 13amps, will the yamaha stay out of overload? If it will, then try 16 amps.

The Yamaha "v2" is advertised as being able to run for 13 minutes at max current. I do not own one, but have been thinking about buying one, so I'm interested in how it works out for you.

Yeah, I just opened the manual as saw 13.3 amps; at a power factor of .8 it is only good for 1280w. That isn't enough even for steady state. Houston, I think we have a problem. Even in hybrid mode, it looks like it would need the inverter to run. Hmmm.

Yep, they are too lite, especially if running steady under full load..

Not even for a breaking period? My Yamaha 2400 had to be run on gas for something like 4 hours before using LP. But this was a few years ago.

Larry,
The published normal/max current ratings for the two are virtually identical. I have read that the Honda is rated to sustain max for up to 30 minutes, and the yamaha v2 for only 10 minutes. Is that what you mean, or are you saying the actual normal output of the honda is higher than its ratings, or are you saying the actual normal output of the yamaha is lower than its ratings?

[sburrw]

I use the Yamaha 2K gasoline model with the Easy Start with no problem. Make sure your system is not pulling a lot of amps to charge the batteries at the same. That was my problem at first. I had to change the Magnum settings to the lowest possible amount of battery charging while using the generator to run the A/C.

[lsbrodsky]

I just did a fair amount of research on this; I have the Yamaha EF2000is, NOT v2. There are some Q&A's on the web that make it clear that Yamaha upgraded the controller to allow it to run longer at high amperages for high draw appliances. This was not the case for my 2000is. Since the power factor of the A/C is less than 1, it appears that my generator cannot even handle the steady state load of a 15k A/C.
The specs for the v2 do look identical to the Honda. Matteo tells me that some folks on other forums have had success with the v2 Yamaha, but he has no personal experience. Nevertheless, the published Yamaha specs indicate it should handle a 15k A/C on v2. My older version is a nice quiet battery charger.

Larry and I just spoke by phone. There does appear to be a marked difference between the EF2000iS and the EF2000iSv2. Check out FAQ #1 on a Yamaha Generator distributor site at this link, and the first Feature bullet on the corporate Yamaha site at this link. There is no doubt that the EF2000iSv2 was designed to be better than the original EF2000is and be more like the gold-standard Honda EU2000i.

We at Micro-Air were unaware of this difference before. So the reports we received from past EasyStart customers who met with success with their "Yamaha 2000W" generators likely had the v2, but never specified. I'm investigating one customer again now to find out for certain.

I'd be curious to hear which model you have, sburrw?

[kscherzi]

I have the Yamaha 2000 V2 and my 15k AC started and ran fine on the easy start. My generator is filled with gasoline. I only ran it for about five minutes though.

Hopefully, You'll have some time to run it with the a/c and Yamaha for at least an hour. If you do, please report back as to what happened. I'm on the fence trying to decide which gen at this time.

Matteo, how long did the Honda 2000 run the 15,000 btu a/c in your tests?

Continuously. We have a 15k Dometic Penguin II at the factory, and the Honda EU2000i. You can run the Honda EU2000i generator right up to its 16.7A 2000W limit, and it will continue to output power without even a hiccup, until it empties the gas tank. Exceed 16.7A by a half amp or so, and it will shutdown and declare its overload fault in about 10 seconds, more or less depending on the extent of the overload condition.

[heitkergm]

I had no problems at all with my Yamaha V2. It starts my 11K Dometic Penguin (not Penguin II) fine with the easy-start. Runtime draw is about 10-11 amps.

I was initially confused, as the Yamaha V2 and Honda have almost identical specs. The clarification that the original Yamaha 2000 had less output fixed that confusion.

[SCOTTinNJ]

Are you 100% sure there are no other loads? Can you isolate the battery charger and completely shut it off. Fridge? Water heater? Other electronics?

[lsbrodsky]

I am sure, just the clock on the microwave. There was a dribble for the charger, but the battery was only charging at 1 amp DC.
Larry

[GMFL]

I just ordered one. And don't even own a gen set yet. It will reduce the over all load on my 30 amp service so maybe we can run the electric water heater AC and my wife's hair dryer all at the same time

[lsbrodsky]

Huh? You do not want to try to run a generator in parallel with shorepower! I do not think there is any way to try since there are not two input connectors connected at the same time, but do not try.
