Brand New DuroMax Not Producing Power! #hvacguy #hvaclife #hvactrainingvideos

I was a generator technician for 30 years. Your wasting your time thinking it's some sort of break in issue or something your doing. These modern INVERTER units are complex and something is wrong with it. Take it back. If it was shutting down from low oil or some other fault condition, it would probably be apparent. Unfortunately there is no good support network for the huge amount of equipment being sold in the US. Most of it is IMPORT. I don't know if that machine is but finding any facility that would fix it would be difficult. I repaired Onan RV machines as well as welding equipment. Inverter style machines have become the norm and they are far different and more complex than older machines. Since you did nothing to it other than follow the instructions you should get a refund or a replacement......

Maybe James Condon who has a great you tube channel could offer some insight.

If you look close. It's going from power to overload which will kick you off line. Return it as a defective unit.

I'm in the market looking for a high wattage portable inverter generator. Based on this video and reviews , this brand has been thrown out of my mind even considering for purchase. Great video

ok, by 4:03 I suggest never transferring the whole house load at once, as it will likely have way too high of a "peak draw" for it to overcome. especially with all of the switch mode power supply/highly capacitive devices of today, including LED bulbs/dimmer/chargers/EMC motors (the list is really endless) in power outage, go inside and turn off "all" breakers in the indoor panel, then outside and transfer the "main/generator disconnect/interlock". now go back inside and slowly turn on "ONLY" the important required circuits, while being mindful of delayed starting of appliances/hvac/other gear! **trying to directly transfer the whole home load at once, could draw peak surge currents in multi-thousands of amps! that will clearly overload most any generator. I seen a few of the other comments saying it's the generator and etc. BUT now days, the huge capacitive loading can and does blow the power company HV fuses, if a voltage changer transformer switches taps or line work triggers an short power outage.

Mine did the same thing and I took it back

In the famous words of Elvis , Return To Sender ... Thx:hand-purple-blue-peace:

Electronic issue. 3KW is more than enough for power sensing, and only 1/5 of your rated load. Return it for a replacement. The inverter electronics are faulty. May be a bad feedback power gain issue with the inverter output power sense. Break in has nothing to do with it. As a side note, does it still do it with the eco mode idle control off? If you have an amp clamp, set it to max capture on each leg of 240V and see if something is spiking the inverter. I doubt it, that inverter should be able to handle a 75-100 amp spike.

Defective unit. return it.

It has nothing to do with break-in time. Bad voltage regulator is probably the issue.

That generator without doubt has an internal Automatic Voltage Regulator (AVR) issue. You're doing nothing wrong, that generator is defective.

The best generator guy out there is youtuber James Condon. Reach out to him

Love your videos!!!!

Hey Curtis, just a few thoughts. At 3.2 kw, not knowing how much is 240 and how much is 120 we're loosely around 13-26 amps, and it looks like you're running off the 50 amp circuit. I put soft starts on units a lot now, and have them on all of mine. My 5-Ton went from 147.8 Amps inrush to 33.6, 3-Ton on the guest house went from 96.74 to 25.1, office 3.5 Ton went from 78.09 to 22.4, and my office managers house went from 78.08 amps to 28.0 amps. All were done for generator and longevity purposes. I suppose I should have asked if this happens when you're not running the A/C. I do feel your pain though. I bought four Westinghouse WGen20000 generators to get two that actually worked. Thanks for the great videos. I never miss one.

5:27 The overload light is coming on. According to the rating on the side, any surge over 66A on either phase will overload. The plug is only rated for 50A, and that's about all that unit can do. You probably have a 100A service to your house. The generator is probably not going to be enough to run your whole house the way you're used to. You're going to have to limit what's running. Something might be trying to start and causing a surge the generator can't handle. Second - is that a solar panel on the roof I see? That generator isn't going to tolerate having a solar system try to feed excess power into it like you can with the power company. I'd start by turning off any solar and then limiting the loads you have. You might also try using your amp meter to see what's really being drawn. Make sure one phase isn't overloading the unit.

You have the equipment to measure the peak load current, if it is within the generator specs, then it is a faulty generator.

Our first Generator was a Dura Max and quit running after 1hr. only had it connected to the cord that we special ordered for that brand. We took it back the day and the store started it and after 1/2 hr it quit. We ended buying the Champion with their special cord. That was back in 2011 and it still runs great. We also purchased a special tent for the Champion for using when it snows! I'd take it back!!!

I repaired large Inverters for a living, also worked in a electric motor shop for 9 years, early in my career. I tried finding specs for that unit. Each time you lost power, the overload light came on. I am going to suggest you try something. First turn the breaker for the AC unit off. Next turn every electric load you have on in the house. Preferably, a electric dryer, turn it on first. Next a electric stove if you have it, turn the oven on, and some burners. You may have a pannel imballance, although I strongly suspect this is not capable of starting anything bigger than 2 HP . Inrush current is typically 6 to 10 times run current. So a 2 HP is 1492 Watts times 10 = 14.92 KW, A AC unit of 2 Ton ( which is what I used for calculations), or larger may not start with that generator. I would be willing to bet, you could run right up to 14 KW continuous, provided say like a dryer, was started first -That is all motors were started first before additional loads were added.

Repeat the same and slowly ramp up the loads in your house. The problem may be you are overdrawing only on one leg. The AC may be the problem with its LRA in combination with everything else. Put you amp clamp on the different 120 v branches and you might be using only one leg. Measure the amp draw on each incoming leg. It sounds like an overloaded safety circuit is cutting out. Check for loose connectors, everywhere. Feel the breakers to see if they are warm. You may be returning if nothing shows up on your end. My first suspect is the AC startup. Measure your pump startup draw. You may need a variable speed AC. Mine draws 16 amps on high and much less using only first stage and never any LRA.

Curtis , Put a Amp Clamp on Each Leg in the Panel serving the Load. Set the Meters to capture " inrush " Watch Your Meters and see if When something kicks on it's more than what the unit is rated for. Remember --- You can only Pull 50 amps the way You Have it set up right now. You are only using one Outlet. maybe not even 50 /outlet. check book. No Matter what the Generator is a Rated at You Can ONLY pull 50 amps on that one Outlet. i'm guessing the when the a/c unit kicks on the unit kicks out. if so check in rush on a/c unit condenser & see what generator is specced for. if it's within spec. Return unit as defective. for testing purposes - Plug in a bunch of stuff in the generator it self - when it's NOT hooked to the house. plug in a couple 1,500 watt space heaters. some halogen lights etc and just see if generator will work properly When NOT hooked to the house. If it does not even work when its standalone - Then Return it as Defective. as far as Break in time - You have done plenty. a couple hours is plenty. Check the Book as Far as Grounding. what they want. just read that part. see if higher loads require a ground rod into the earth. to Eliminate static or noise on the line. But , First check generator stand alone. on Resistive Loads First. That way Thier are no spikes & You are Testing a Steady Load. if Generator kicks out under steady resistive Load. its Faulty. Return unit as defective. Monitor voltage on the 115 volt lines with 2 " Kill - a watt " meters. while testing. Watch James Condon on youtube - His testing method is at the End of Mist of his videos. He is pretty awesome as Far as a Generator guy testing & Fixing portable generators. He Makes Great videos & is Very knowledgeable. Good Luck ! 🍀
