Anyone running the Dometic LW3000 Plus Digital Inverter? It's a 3000 watt unit (not sure if that is peak or continuous)and I picked it up for $800.00 plus taxes at the recent RV Dealer show in Calgary Alberta. Brochure claims it make 59db at 4m or 13' That is at idle from what I can tell. It comes with a battery and a keyed ignition,but the battery doesn't seem to want to hold a charge :R No matter, turn the key to on choke it, pump the fuel bulb about 6 times and a cpl pulls on the cord and it fires up. Had to purchase a twist lock adapter to hook it to the toy hauler. Unit comes with a few basic accessories but no oil & it uses 15w40 (just under a litre/quart)
Since I had a Hyundai 1000 watt unit (1250 peak) I decided to perform a side by side comparison using a 1500 watt ceramic type space heater. It was filmed using a Canon Power Shot A530 mounted on a tripod
Here's a Dometic Dometic LW3000 Plus Link to the comparison that I uploaded to U-Tube
Are you comparing this generator to the Champion 2000 watt inverter?
I poked around a little after watching your video. It looks like a Magna generator retagged. I have the non-electric start version. It was ok, but definitely not the 3000 watt one might assume with the model number. I took mine apart and the inverter module had 60hz 2kw written on it. I'd be damned if I could get it over 2000 watts without it going into overload. The specs on mine was 2600va running and 2800va max. I believe that this is the actual capability of the motor's output, but once passed throught the inverter, there is a loss of power and your probably good for the max of about 2000 watts. If you just bought it, you should hit them up for a battery. Mine sits in the corner of my garage. I had problems with mine stalling when a small loads were applied. It wasn't consistent. I believe it to be a fuel pump issue. The fuel pump was operated via pulses from the vacuum created from the motor running. Yours, I believe has an electric pump to facilitate starting with the key, otherwise, you'd have to pump the bulb around 20 times to get the fuel up to the carburetor. (per the manual) I had taken a tank of fuel and elevated it, creating a siphon to the carburetor. What was once a skipping motor became a smooth running motor and then it would no longer stall when starting reasonable loads. The company I bought it from did one hell of a marketing attempt on Ebay and taught me a lesson about these generators. Or this type of marketing. See, this fella blocked all of the reviews and links to the garbage he was selling. When contacting him, he was not very nice.
Anyhow, get your battery replaced. If you paid 800 bucks for it, it should work. Next, the 59db is rated at an idle. Mine was quiet at an idle and significantly louder under load. As far as starting 13.5 ac units, I believe that design and availability of a hard start capacitor will determine whether that is possible. (from experience) Test your unit to see if you can come close to 2500 to 2600.
If you are looking for the Dometic LW3000 generator reviews or posts, do a search in the area to the top left of the screen. You'll find some additional info there.
One link to the tech area of Dometic LW3000Your open frame Hyundai generator is taking a significant hit in RPM's while attempting to run that heater. You can get a clamp on meter, place the leads into the output and select Hz. to see what your getting with that load. I am willing to bet it is slowing down to the 50 Hz. range.
Good luck with your generator.
