The manual will tell you to run with eco off when powering items with a heavy surge. You have several of those. The problem is the eco mode cannot increase the rpm fast enough to deal with surge so it tries to make up using the inverter output and that drives it into overload. Just leave eco off to run your whole house.

We live on the Mississippi coast and have had our problems with hurricanes over the years. This would be a great set up to have! Thanks for the video!

Thanks for testing the Central HVAC and showing us how it worked! That's exactly what I'm interested in. I would love clean power but I'm concerned about motor starts on an inverter. This looks very promising; I was amazed that you could start the outdoor compressor on low idle.

That is awesome. It covered the house with power to spare. Compared to most generators, it wasn't that loud. I don't know if you have natural gas, but if it can be converted, there would be no need to run for propane. I don't know if it is true for that one, but they claim you have to give them a cool down period every 4 hours. I have used generators before, but nothing of that magnitude. It looks like a badass machine to me. Thanks for sharing.

Now that's a generous generator

I run my Honda with ECO off, since a motor or compressor sags the voltage too long when starting. Great job!

Well done Curtis, that is a nice capable generator 👍 Au

Love your Wymarana! Geni looks pretty good too!

I'm looking for a more powerful generator and was looking at a whole house generator, but the sticker shock was making me look elsewhere. I had no idea inverter generators have increased their power this much and I might just go this rourte. Great video!

I have the 13kw dual fuel Duromax as a backup to my 22kw Generac whole house genny. These are nice units.

Man, that's a monster!!! I don't plan on using my new 7500W tri-fuel Firman generator ($700 @Costco) on gasoline either. Maybe I'll run it one time on gas just to be sure the carb works and run it dry. Should we be putting anything in the fuel tank to prevent rust? Fogging oil or swish around a little Marvel Mystery Oil maybe?

Our Power Company in STL Cut Tree Trimming Program causing Major Outages after 2006 Tornado and 2006 Ice Storm. Installed Natural Gas Generator, 12/2006.

That monster is going to swallow that tiny propane tank like nothing.

low idle mixture is to lean also that tank is only about the equivalent to 4.5 gallons of gasoline

That is a big giant beast all I have are two predator 3500s in parallel so I can get 50 A at 120 V and I just run a couple of window shakers and it runs my other stuff that I need just fine, but I don’t have many 240 V items in my house. My hot water heater is natural gas. Basically just my stove and my dryer. I can’t use in a power outage, but I have a hot plate and a microwave that is good enough to cook with in a power outage maybe one day I can get a big one like that

Good deal Curtis, Yeah propane burns cleaner than gasoline, but less rpms, if you use the gasoline on the generator it will stink it up like a leaky car.......

During break in, you should use non-synthetic oil. I thought I saw Mobile 1 but I could be wrong. Also, heavy inductive loads you should turn ECO mode off so that there’s no surge on the inverter system. After break in I think you can switch it back on. If there’s a surge over a certain value the inverter will trip off to protect itself. So during summer when the A/C kicks on, ECO off will allow the inverter to pull that power it needs with no surge. Finally, if you have issues with the engine having hard start after break-in, put Bosch platinum plugs in the engine. Those Chinesium plugs are NFG. A friend did that in his generator and fixed a multitude of problems he was having with the engine. He has a Harbor Freight 9,500 watt generator. Excellent video. Thanks for bringing us along.

Check the manual for that system. I think you need a bond to ground via a ground rod right at the generator. Also check the grounding requirements of your electric provider and ask a local licensed electrician. Calculate propane consumption perhour and then the expected time backup power is needed. That will help you decide how big a tank you will need to have filled up. My preference would be using Natural Gas. The last time I had lost power it was about 10 days.

Invertor is much quieter than a open frame (contractor generator)

Can you post links for everything you used to plug it into the house please?

High idle as You stated is not an idle at all. It is running the Engine at full 3600 RPM... When You were running low RPM The inrush currents were to much for Propane to overcome.

when the power is out here, I go with minimal needed equipment/lighting powered on. well pump, some lighting, fridge/freezer and cooking appliances( one microwave and gas oven) although I will generally just use the gas grill outside, unless storming bad. the rest is un-needed, but handy. I don't bother with backup power unless it out or is said to be out for more then two hours.

you may need a bigger tank of LP , once you start to get above 5Kw you need allot more gas , that small tank may not be able to produce GAS lp fast enough. there is a kit I seen to connect 2 tanks together to supply enough GAS..

These large gens are great for short term use. 1-2 days. Now paying for and storing enough fuel for the long term is another story. I would like to see a 20lb tank hooked up and time run time. This will help to calculate larger tank size and run time in emergency.

Nice product & nice demo ... Thx

👍👍👍

I've found on inverter generators that when pulling hard starting things keeping it on hi idle is better For the generator. I have a 8500 watt DuroMax generator runs my house well. The new heat pump ,I installed a soft start on it haven't tried it yet but I hope things work well on the generator and Ac. Curtis what do you think about the soft start add on?

At times I wish my Honda was inverter but it manages clean enough power to handles my audio and video equipment as well as my computers. Talk about your 50 amp cable being heavy all I had when I wired mine here was 4/0 UG 😅 The 50 amp breaker might trip but the ug won’t burn up lol Glad I did utility work in a previous life so I had the Burndy crimp tool and plenty of block splices lol

Nice quiet duromax

Propane is King during any mass emergency situation. Propane can be stored infinitely and is reliable unlike gas and natural gas supplies. IF a potential long lasting power outage occurs no matter what fuel choice selected it will be highly sought after and in low supply so its best to not waste any of it such as using oversized generator producing power you don't need nor will ever use. No need to power entire house and cooling every room using homes central air.. Best to select a room such as master to use as a temp living area to stay cool, add it to one of your circuits of choice for power. Pick out a nice size window AC unit or portable one to use along with a moderate size generator in the 6500 kw size to power it along with few other circuits such as well pump, fridge etc.

Wondering the kW cost when using propane. Is this cheaper than the outrageous rates the power company now charges?

Not supposed to use Low Idle with house backup hookup - it's right there in the manual describing the function of that button.

Running on propane you don't change the as often as you would on gasoline on propane it runs so clean

Just heard the Trifuel (incl NG) version of this model is coming out. Wish I had waited instead of getting the 9KW Champion Tri Inverter. But it was only $1350 so I can get two.

What did you do with you Predator inverter? It would work fine unless you turned on everything.

Propane is less powerful than gasoline, so you'll go thru propane faster than gas. But propane doesn't go bad from sitting and gum up the carburetor like gas does. So with propane it can sit for years and start right up. I work with marine diesel generators. You may need some hard start kits on some motors if you're marginal on power.

At 9000 W at 240 V you’re pretty much at 47 A on that one circuit you need to hook up the other 50 amp cord.

Cool Generator. What about Trying to use the Broiler in the oven or the stove top To Boil a Pot of Water for Spaghetti. a Propane Barbecue , That Generator & a 100 or 200 gallon Propane tank & You are all set for a Week or 2 without power. Smart man not filling with gasoline. that way you don't have to worry about gumming up the carb etc. i would not use gasoline either unless You have to. just takes all that gasoline & varnish out of the equation. You should try living with it for a Weekend once & see what happens. it would be interesting. see how long a 5 gallon propane lasts. You could use refrigerant scale figure 1 lb of propane for how much time.

also to note, you should do a fair break in period before applying the house load/equipment. run full speed no load for a while( 20-30 minutes), then apply half load for 20-30 minutes (portable heaters work well, outdoors, in cooler weather). then vary the load from about half to 3/4. stop and change oil! (units with or especially without oil filter/pressurized lube).

All electric house, he needs to go big on the inverter.

Do you recommend soft starts for your AC units? Great video. Thanks

I just checked the price. $5K? Uggghhh....that's expensive, but might still be worth it.

Love this generator just don't understand why they don't make it tri-fuel. Most folks would want to run NG on this.

Here in san jose power outage you lose cell phones too. wifi is nope..

Turn on the inverter devices on it economical in electricity. Regular air conditioners consume high current while they and electric heaters are starting their work. etc

Propane tank should be a 30lb minimum

FYI an 18LBS propane tank isn't big enough to supply it ever(other than full tank short test/low output) otherwise you'll want minimum of an 500 gallon tank or far larger to feed it for any real sustainable usage in an power outage.

As far as I know you can't use propane & low idle that's for gas only &. According to instructions

What Is The THD Rating?

Will it convert to natural gas?

think it would start a 3 ton rheem LRA 79?

After adding oil, throw away that battery and hook up a normal car battery that has a solar charger hooked up to it.

Hard start capacitors appear to be more effective and cost-efficient than soft starts for AC compressor motors. After installation, I observed a more than 50% decrease in amp draw for both starting and running units. (4 ton)

Strange Duro-Max doesn’t recommend break in with gasoline. I have a 12000 dual fuel Duro-Max and the manual recommended running for 5 hrs with gasoline to break it in. Anyway…

They are so nice but too pricey for me.

Not tri fuel that’s just nuts why not is the question

$5000 msrp, ouch. $6300 will get you a Kohler stationary unit with an auto transfer switch. A competent DIY'er can install either themselves if they do their homework. Not sure this makes sense at this price point

You didn't mention that you satisfied

DO NOT BUY DUROMAX GENERATORS UNTIL THEY HAVE PARTS AVAILABLE. NO PARTS ON WEBSITE OR AMAZON, NOWHERE ELSE. CORRECT ME IF I'M WRONG

Any company that makes big generators that work on propane, but not natural gas, should face massive fines and jail time for all executives and board members and their families and childhood friends.

You should never use synthetic oil to break in a small engine.

I'd have thought these invertor generators would be quieter than that,not much difference between that and a typical generator as far as sound but price i could get two regular generators as compared to one of these.
