Load Testing the GENMAX GM10500iETC on Natural Gas

[@maks2772]

Gavin Thanks!! for being so precise in the explanation of the different types of hookups.

[@Tom-In-Ga]

That thing's a beast! Great job reviewing it. I think you're quickly becoming the Guru of generators on YT.

[@GeneratorReviews]

Thanks 😊

[@2CODO1963]

Excellent real-time load test. This is definitely more convincing than any other load comparison with other units.

[@bayouslots3143]

I have done many conversions to natural gas with kits. The main issue with the conversion is jumping between lpg and natural gas fuels, you have to adjust the air/fuel mixture it's small amount but makes a difference. If you go back to gasoline no need to adjust a air/fuel mixture. Now the fun part, if you want your generator to run at full load on natural gas or lpg you must adjust the rpm's. "BUT" big BUT if you swap back to another fuel the rpm's will be off and over run your generator. That's why I think tri fuels from the factory have a lower rating on lpg and natural gas, not having to adjust rpms finding a happy point between all 3. I think that unit is worth money especially if it has low THD. Great work Gavin!

[@AdamFeldman42]

Is there a good guide somewhere on tuning RPM for NG conversions?

[@bayouslots3143]

@@AdamFeldman42 No guide that I know of, engines and models adjust different. You can google or youtube your generator for how to "adjust RPM's, you will also need a small engine tachometer. Do this at your own risk, first time I tried fudge it up. Loosen governor in place of just making a small bend to the spring holder. Most of the time it's only about 300 to 600 rpm's but it does make a difference.

[@Moondoggy1941]

First of all Natural Gas burns cooler than propane, that is why they have a different orifice and spring load on the regulator, second it is impossible to get a standardized fuel pressure system in the US, some areas are better than others and others areas are nearly impossible to achieve, this why I think most manufactures want to use gasoline and propane. This is why you need to know the WC rate of your natural gas for the region, we have 8" WC so we are good, some areas around us how High Pressure but you are not allowed to tap off those lines, big problems doing that.

[@Rockrewls]

Great video, Amps ratings for the GM10500iEt Tri-Fuel Inverter Generator, on Gasoline 120v 70.8 Amps 240v 35.4 Amps, on Propane 120v 66.7 Amps 240v 33.3 Amps, on Natural Gas 120v 56.7 Amps 240v 28.3 Amps.

[@tmanning4usa]

It looks like it can run that heater at 7200 watts without overloading even when the generator only rated at 6800 watts on natural gas very impressive thanks for the review.

[@zrkn1]

Genmax is looking so good, most gennys can't reach their power rating yet Genmax goes above and beyond again and again. No wonder you want to be a dealer for them. You get what you pay for in generators. Very nice, Thanks!!!

[@GeneratorReviews]

Yessir not to mention all the research and development that goes into producing GenMax brand. More options and fully loaded Generators Great warranty and Customer Service.

[@zrkn1]

@@GeneratorReviews I can see that they pay close attention to customer wants and needs.

[@aaronrunkle]

Sure looks like a winner to me. Nice to see it working off 1/2" NG line but do be aware there is some ymmv here based on your local line pressure.

[@ChatGPT1111]

Thanks Gavin! You are killing it with all the angles! I can't wait to get one of these Trifuel + Inverter gennys.

[@brandonnelson4164]

Why the jump cut from the start at 5:12 to directly running without showing how the generator handled the load?

[@WiredRC]

Loving these videos just picked one up from you. Thanks again for your help!

[@GeneratorReviews]

Thanks buddy 👍🏾😊

[@browsedeweb8834]

Having two of these in parallel would be a nice grid down setup on natural gas.

[@0lloydb]

Trifuel is where its at!! This is an awesome generator. Awesome reviews. Encourage your contacts at Genmax to make a tri-fuel version of the 7250!!!!

[@GeneratorReviews]

I have spoken to them about that and I will keep reaching out because we need a tri fuel 7k and 9k inverter also.

[@2CODO1963]

The fact that GenMax includes is interesting to me a 1/2" hose is included when I was under the impression that you needed a 3/4" hose with full 3/4" connections for NG gensets.

[@sae1964]

Really nice 👍 buddy. That generator is a monster. I don’t farsee not being able to run the entire house on gas or propane. Did you have a video on that watchdog adapter? Or a link I like to view more information about it. Thank Gavin. Keep up the excellent job 👍

[@katyair1]

that's a nice one, and I like the tri-fuel versatility!

[@steveddavis]

Always interesting information!

[@paultice610]

That generator is a beast 😮 great video as always thanks

[@JaromMcallister]

Makes me want to go and buy a Natural Gas Gen.

[@2005Pilot]

Very Well Done!!

[@TomDolezal-n6c]

Hi Gavin... thanks so much for sharing these videos. One question... when running your heaters to create a load, shouldn't one use the bonding plug to create a bonded neutral?

[@Egleu1]

Those 240v heaters don't use a neutral.

[@kevinr5187]

I wanted one of these trifuel Genmax really bad, but could not justify the price. Plus I read several review that the build quality was not always that good. Instead I went with an open frame Westinghouse 12500. You get 500 more watts on natural gas than the Gemax. I know it will be a little louder, but I can get past that.

[@scottmichel9582]

I love this thing...

[@JG-gw3up]

Great video. What size NG hose is that? At these power levels, you want a 3/4" NG hose, because you will be needing upwards of 130,000 BTU/Hr. A 25' 1/2 inch hose can only deliver about 95,000 BTU/Hr, but a 25' 3/4" hose can deliver about 150,000 BTU/Hr. Using a too small hose is like breathing through a straw.

[@GeneratorReviews]

95,000 BTU is more than enough for two of these generators after one of my customers had someone calculate the BTUs ratings came up with 35,000 per unit.

[@JG-gw3up]

My friend.... don't be so sure! 35,000 BTU is about what my 3 burner Webber gas grill needs! And it has no motor. You might want to look at the manual for that Genmax. My 8,000 Tri fuel Champion generator (100416) is smaller, and according to the manual on page 33-34, Champion says undersizing the NG supply is the #1 reason for under performance. Champion 8,000 watt Tri fuel needs a maximum NG flow rate of 135,000 BTU/Hr at 5-7" of WC. See P.34 of the manual. (link below). And that is to just generate 7,000 watts on NG! So, unless Genmax has somehow figured out how to extract 3X the BTU per CU/FT of NG than all others, your Genmax must need at least as much - if not more - BTUs of NG to run at a higher power! I tried to find a Genmax manual online to see what the manual says, but was unsuccessful. The Champion manual can be found here: www.championpowerequipment.com/wp-content/uploads/2022/07/100416-om-english-21APR2800000-Y2203160048.pdf

[@timothygrable2099]

I wonder what the rated amb temp is for? Says 77 degrees. I wonder if that's for sustained full load. Because that won't cut it anywhere in the south.

[@brianh2497]

I have to get one of those. As always great video!!!

[@no1but24]

I was looking at that one but unfortunately my gas meter is at the front of my house and I run mine on propane in my detach garage with the big door half open and Back feed through the garage, works great but doing it that way I can not use a interlock but I made signs for me to remember to shut the main off first.

[@justforfunphotography01]

Did you just tap into existing gas line? I want to do this! I have a stove with gas line that backs to exterior brick wall right below electrical box. I think i can t in there. Most installations i see them going from gas meter. My gas meter is on the opposite side of house from electrical box. 😢

[@GeneratorReviews]

Yes that’s all you need to run this generator

[@TheSnakeman3]

That’s very impressive. 💪🏻

[@fb510m]

What is max natural gas hose lenght please?

[@GeneratorReviews]

I did my test on 50 feet and have zero problem

[@Flipping_Assets]

What does the watchdog do?

[@GeneratorReviews]

It’s a surge protector

[@alanmarbaker7478]

Another great video!

[@AdamFeldman42]

This is awesome! What pressure is your natural gas meter regulator? Some homes are 7” WC (inches of water column), and others are higher. What does the generator require for BTU/hr?

[@AdamFeldman42]

The specs in the video description say it uses 3.27 cubic meters of NG per hour, at 100% load. That’s about 115.5 cubic feet per hour, or 120,000 BTU/hr.

[@RogerSchreiber-f4e]

Did all of those fittings come with the package, or did you have to go buy any adapters or nipples?

[@GeneratorReviews]

All the fittings come in the box

[@jonathanlee6444]

Man wish duromax made a trifuel inverter. Is there anything I need to do to hook it up to my interlock. My duromax 9000ih I had to remove the bonded neutral

[@GeneratorReviews]

No there’s absolutely nothing you need to do this one comes floating neutral

[@michaelabbott8431]

Great Video. 👍

[@TOURMANBOB]

Do you know if this is a "floating neutral" generator or a "bonded neutral" generator. I need a floating neutral to interface with my Generlink switch, and my Honda EU6500 is that. But it will cost $1000 Canadian to convert to natural gas so better to buy a dedicated tri fuel unit as long as it is a floating neutral generator

[@GeneratorReviews]

This one’s a floating neutral

[@TOURMANBOB]

@@GeneratorReviews SUPERB !! Now I have to figure out how to get this in Canada to replace my Honda EU6500 and have a home backup that works on natural gas. Unfortunately, the TMG Industrial generator which looks to be almost an exact copy of the Genmax, is "bonded neutral" so can't be used. Also converting the Honda to natural gas through PMG Technologies will cost me almost $1000 for parts and this makes no sense when I go to resell the unit. So, at this point, I'm in limbo................

[@petef.4361]

Could this run a 3.5 ton central AC unit, without installing a soft start on my A/C? My ac pulls 5kW when running I think. So that leaves about 2kW headroom on natural gas. If not on natural gas, what if I ran it on propane instead, could it handle it?

[@GeneratorReviews]

Installing a soft start is the best way to run your AC unit on a generator

[@Iaiashgamer]

​@@GeneratorReviewsdo you have a soft start on your rv? If so do you have a video on that?

[@laramie_1944]

thanks for the show Gavin. So, if it’s running on natural gas, will carbon monoxide be a concern or not? You mentioned it smelled like a stove, so I thought maybe CO is not a concern, but I’d like to confirm it with the expert. Thanks again.

[@GeneratorReviews]

Yes, you still have to run the generator outside 10 to 15 feet away from any opening just because you’re running on natural gas that still applies.

[@cory5890]

GENMAX GM10500iET Available soon at Gavins-garage.com

[@woody4u247]

Genmax definitely proving itself to be a quality product.... anxious to see the max 240v amp output on gas.... see what it can sustain without tripping the breaker.... it claims 35 amps on 240.... Would like to see how the load cell shows power divided when two of the big dogs are in parallel (9k or 10.5k) .does one max out & the other pick up the excess, or does it split the load evenly? .. the plug is rated 50 amps... so what happens once it reaches its max 50amp load.... if two big ones are paralleled, theoretically capable of over 60amps even with the 9k... do you simply get limited to 50amps?

[@bovine71211]

When will this unit be available to buy? Also can you parrell 2 of these together like all the other inverter generators?

[@GeneratorReviews]

It should be available by June or July. And yes it can be parallel.

[@paul9387]

On this one, you've been using 30amp Surge Protector?

[@GeneratorReviews]

No that’s a 50 amp surge protector

[@paul9387]

@GeneratorReviews Since this heater you said it 30amp, you used an adapter from 30 to 50 to hook this up to a 50amp surge protector, right? Also, I'm just curious, could this test be done on a 30amp outlet? Also, this heater is 220v. I thought you could not get that with a single unit without paralleling to of these

[@jbhobbyist9372]

If I run on natural gas for 4 hrs straight what's that going to do to my gas bill? Compared to propane at 5.00 per gal

[@GeneratorReviews]

Natural gas is cheaper. it will be like running your heater or water heater or the gas stove.

This is a really nice genny, great review Gavin. I think all generators produced today should be tri fuel. Living in Houston just went thru a power outage for 8 hrs. I have the WEN 56380i 3800-Watt Inverter Generator that I converted to tri fuel. Was able to run lights, router/modem, TVs, refrigerator, and 8000btu portable A/C. But it has it limits and would like more wattage. It makes sense to run on NG endless fuel supply.

[@TOURMANBOB]

UPDATE: Bought the TMG Industries almost identical copy of the Genmax (made by the same Dinking company in China)and it works perfectly with my natural gas supply. Now just have to go into it to remove the grounding to make it floating neutral. I plan to put it on a switch to allow me to go between modes as required.....floating for home use and bonded for tool usage
