Battery minder/tender for battery ?

Congrats on the GenMax. Got mine almost a year ago. Change over to floating neutral will take about 30 mins. When I did my break-in, I connected two air fryers and just let them cycle to change the load between 0%, 25% (with one on) and 50% (when both cycled on) and did it all on propane. But the best thing I did was install the MicroAir Easy Start on my AC unit. On my post break-in test run, was able to run the AC, most everything in the house, two fridges, microwave, and coffee pot without exceeding load limit on propane. My plan will include running on regular pump gas, followed by a 'clean out' on ethanol free gas that I make myself, followed by a short time on propane. And you are right, this this is QUIET! Enjoy.

Thanks you for your review of the GM9000iED. It confirms why I bought one last year. Royal Purple recommends using the break-in oil for autos during the 1st 500-1000 miles (8-16 hrs @ 60 mph) and then switch to synthetic oil; so I am switching after 8 hours. Break it in using gasoline. For those of us confined to urban areas on the Gulf Coast; our choice it natural gas not propane. This is an extremely easy generator to convert to natural gas; no expensive conversion kit required. My generator started on natural gas just as easy as your propane test. I was able to have the house circuits powered; then started a 4-ton AC (ran this way for 30 minutes); and finally started the 2nd 4-ton AC while the 1st was still running. I have 2 Hyper Engineering soft starts installed on the compressors (soft starts are required in order to start a compressor). After 5-10 minutes of both AC's running; the generator overloaded and tripped out. The load meter was showing around 6500 watts. I never plan to actually try to use both AC's except for this test. I am happy. I posted a detailed procedure for the conversion at Power Equipment Forum under the Generator forum. A special demand regulator and large hoses are all that is needed for the conversion.

I’m surprised that at least a few people have figured out they need a generator 😊

Great no nonsense review. Way better than many i have watched. Thanks for outlining your research and why you went with the Genmax. The minor mods portion was super helpful too.

Exactly what happened during my research. Fully on getting the predator...then noticed the little things. The GENMAX and Pulsar also a forced cooled where they push the air along with the exhaust. Your findings validated my findings really appreciate this video.

I actually just purchased the GENMAX 7250iEDC for my 50amp 5th wheel. The GENMAX sold me on the fact that it comes with a 50amp receptacle. I will be able to run both AC's, fridge, water heater, space heater and coffee pot no problem.

Good job! Fantastic work/presentation on your review video.

You can just use SAE30 to break in an engine. Its non detergent oil so it allows for wear with out additives. this way everything can seat properly during break-in. Non-detergent oil its what i used to breaking and seat the rings on many forced induction setups...

Bro. Thank you. This video is perfection.

I decided to go with a Westinghouse 15000/12000 generator based on reviews. I needed more power than 9000 watts to run my central AC, this model has a true oil filter & oil cooler. It uses a V-twin OHV engine and produces less than 5% harmonic distortion for high end electronic equipment. I bought the gasoline model since I plan on only using this fuel but they do make a 12000Dfc model which runs on both gasoline & propane.

Good job on this video!

Nice review ….. I about to buy one and doing the typical KZfaq reviews

Yeah so if you could just keep doing these thorough reviews of all the things I had on the list to buy this year that'd be great.👍

Great video. I’m considering a genmax tri-fuel inverter generator to pair with my maxed out delta pro backup system.

The purpose of the oil screen is to catch any large pieces that would damage the oil pump, that is what sold me on the Genmax as well as one of the Generac units. In my mind having pressurized lubrication is HUGE.

Keep an eye on that magnetic dip stick. The magnet fell out of mine and ended up in the engine sump. I was able to fish it out with a stick magnet. It’s a bad design because the aluminum expands and the magnet falls out. The stick should be made out of steel so the magnet sticks to it even if it gets loose.

Fyi I'm sure you know try getting propane delivered or filled on power outages for weeks it's the same they will not deliver and it is almost out before you get to a home deponor gas station. The only benefit is that you have a second alternative for just a few more days of propane

What I will say about warranty is you must buy the extended at Harbor Freight and it can’t be beat period, Amazon is a roll of the dice . No duel fuel is a deal killer for me too propane is a must. It’s also been reported by repair shops can’t get parts for Genmax

I believe Genmax is the actual manufacturer of all of these similar large inverter generators, who buy ans rebrand them. Obviously harbor freight sells a lot of their units as the Predator. Depending on which 50amp cord and plug you get, if you choose the 90 degree 50amp plug, you will need a plug extender. The front panel gets in the way of pushing a 90 degree plug all the way in. You may also want to get the battery charger for the 12v battery.

you could purchase line conditioners for your sensitive electronics and purchase a less expensive generator... you may spend approx. the same money up front but if the inverter goes bad or the generator does, you can replace it (or them) for less money.

Thank you for the video - excellent summary. Do you have to have two of these hooked up in parallel to get the 50a output? I've seen some generators that have 50a plugs that only output 30a unless you are running two in parallel - or maybe I'm misunderstanding something about that.

Can you confirm that Genmax takes the 3/8 Drainzit hose? Thank you for taking the time to make the video.

How about hitching a trailer to the Tesla so that a generator and gas tank can keep it charged up as a person drives down the road?

I agree with you about the containers - super frustrating. This one time me and my friend Zeus were in central park and we had to weigh 4 gallons of water but all we had was a 3 gallon jug and a 5 gallon jug to work with. Anyway, Simon was a real jerk, but i threw his brother off a building so it's kind of ok. nord des lignes.

Great review. Will you be adding a transfer switch to the house ? If so do touch think this is enough power to run the ac and other things in your house ? I plan on getting a similar set up. I might have to add a soft start to my 5 ton ac first.

Hey Looks like a nice generator. What about Duramax ? Is this same brand ? These generators still lack oil pump lubrication with an oil filter. This is downside but you have a small screen type filter if you can really call it a filter. The magnetic one you installed is better but there’s more aluminum then steel in these units. Nice video

If running it to a 50 or 30 amp inlet box the neutral doesn't need to be changed.

Honda is the best and easy to get parts.

Great Video,Thx for sharing. I just ordered this Generator this morning and was wandering Battery would you recommend?

I am in the market right now. Wondering if you are still happy with the Genmax? I don't trust reviews but do notice a lot of lower or bad ones, mostly about customer service. Just wondering your thoughts after just an initial shakedown. Great videos man, appreciate your insight and humor!

I compared the same ones and came to the same conclusion for the same reasons. Also added the magnetic dipstick, and a magnetic drain plug. Ran mine for 1 hour at idle, changed the oil, then did it again, and again. First hour was black, 2nd better, 3rd considerably better. Love the drain hose in the carb bowl, too, which makes it super easy to store. Drilled a hole on the battery side and put in a grommet to pass thru a battery tender cable, too. Have had to use it a few times and it's been fine. Runs my whole house including 3 ton AC (with soft start) no problem at all. My hour meter resets itself to 0 every time, but otherwise it's been fine so far. Considering the only "name brand" alternative is the Honda at over 3x the price, I can replace this 3 times and it'll still be cheaper.

hello my friend,i am planning buy one for my food trailer,i have no experince with these generator and food trucks at all, my food trailer came with a 50AMP cord but not the genertor, i was planning buy the predator 9500 but was across this unit,its cheaper and seems to be a little better so i may go with this one. my question is, in case i go with one that does not have the 50amp outlet,can i use the 30amp and get an adapter or is thta a bad idea??? and also how good is this genertor for a dalily use or pretty or at least 5 to 6 days a week thanks in advance

I liked your assessment on the differences of the generators. Live south of Boston, When the power goes out, it has lasted up to a week with temps below 30 degrees (winter). just grinned and bared it. Too old for that now. I purchased a duramax xp9000ih, duel fuel a year ago, installed a 30 amp inlet box on the house with a lockout on the breaker box. Had to change the bonded neutral to floating which wasn't that hard and there is NOT a 50amp plug on the unit. Went on Amazon and found a magnetic dip stick that is compatible to purchase but not sure of which drainzit that would fit my drain plug. How do i find that out? is it a thread count or pipe npt? not sure what will fit. Any help would be appreciative. PS.... my power has gone out every year for the past 20 years. Since I invested lots of money in the generator last year the power has not gone out since. Maybe I should pull the trigger on a new snow blower and maybe it wont snow.

?, you referred to not being able to get gas if there’s no power, but you’re still going to have the same. Problem with using propane aren’t you unless it’s delivered and the have full delivery trucks, do you have natural gas in your area? Just a thought.

Got one of these Genmax 9000 iedc and the battery died within 10 months and only 10 hours on the clock. The battery is hooked into a battery minder but it still failed. I called Genmax US service and after is very hard to get to talk to someone. So I emailed Genmax China and they said call Genmax USA. After several hours of trying to call Genmax I finally was told I have to bring it to a 3rd party shop to have the carb replaced at my cost. In any case do you unhook the battery to the generator when it is in a maintainer. I ask this because I have another 7000 watt honda and I just connect to the battery maintainer and it has been ok for several years now.

Quiet enough for a home in the suburbs?

Where can i find a replacement battery ?

Do your knob for the gas and lp turn all the way around? Does it go past the gas option etc as does it point all the way down?? I’m trying to figure out if my carburetor is bad or the turn knob Thank you

I have the duromax. They have an issue. Front panel keeps going out. I am on my third one. I wish Predator has duel fuel. I use these in a Billboard LED Truck.

Which size oil drain hose does this unit need?

Any updates on this unit and how has it done running your whole house off propane

Is there a replacement oil filter screen available??

Thanks for this videos and the links of the parts/accessories you are using to improve the generator. I just started my research and bumped into the GENMAX GM10500iETC. It is a tri-fuel inverter generator. It comes with everything, ready to use, including the hoses for both propane and natural gas. I don't know if there if there is natural gas for sale around me but as you said, better have it and don't need it. It cost $2,900. Yesterday it was on sale $400 cheaper in Amazon but now is at regular price.

this unit gets either good or bad reviews on amazon. have you had any issues with it?

What is the size oil Drainzit did you order? I have ordered two from Amazon now and they have been the wrong size

PARTS AND SERVICES AND WHO?

Now there’s a 10,500 watt tri fuel model.

Very disappointing purchase. Bought one off amazon lasted a couple months now know one wants to warranty this unit. Have calls into customer service but no reply

I can't get past the 90 day warranty on the Predators. If they don't have confidence in their products, why should I? And the extended warranty they sell for the 9500 is $600. You'd be foolish to not get it so add that to the cost comparison.

They are all made at the same Chinese plant use the same engines etc

yeah definitely the extra hour meter you placed inside the engine bay is probably gonna die first.

Too bad it isn't trifuel.

I bought a pulsar and it great!!! Best generator I've owned.

just a quick correction, that generator can produce 75 amps plus so why couldn't you use 50 amp plug to power your house? Also if you use that to power your central AC you should get a soft start kit installed because some units can draw almost it's full out put when starting.
