GENMAX GM9000iED vs Duromax XP9000iH vs Predator 9500 PLUS Mods Before Use

Battery minder/tender for battery ?

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.

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.

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

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.

Bro. Thank you. This video is perfection.

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.

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

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

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.

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...

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!

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 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.

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

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.

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.

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.

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
