Just bought this one myself. Very quiet for the power, and power is clean for the Gen input of my Solar Inverters I use it to charge my batteries if there are long periods of bad weather.

[@SlipFitGarage]

Congrats.... I'm happy with the one I bought. It's been good so far....

[@rkj4107]

I have this same generator. I like it a lot. No regrets on the purchase.

[@SlipFitGarage]

I love it, too. This thing is a beast and it appears to be very well made. Be sure to stick around for more videos in the near future about how I plan to make this quiet generator EVEN quieter, and also about the power accessory box that I made to work with this generator, or any other 240 volt generator. Thanks for the comment!

[@1ronhall]

I did my research and this genny is for me, I thought. Genmax now has a 10,500 Tri-fuel. I’ll connect using the 50a connector. Thanks and great video review!!

[@SlipFitGarage]

Yes, they do now have a 10,500 watt tri-fuel version of this generator. It's pretty awesome! Hey, if you click one of my Amazon links (any one of them) right before you purchase your new tri-fuel generator then I will get credit for the sale. It doesn't cost you any extra but it helps me out. Thank you for the comment and enjoy your new piece of equipment!

[@scottfriedberg740]

This was by far the best video I've seen on this product. Thank you so much for putting the time and effort in on this and being so thorough. I've liked and subscribed. Look forward to more details on making this a safe and future auxiliary power plant for my home.

[@SlipFitGarage]

Thank you for the nice comment! I have two other videos that feature this generator. One of them is about upgrades and oil change service, and the other is about powering my entire house along with my central A/C with this generator. I will link them below: kzbin.info/www/bejne/aoWrmZ2LiMuEpac And: kzbin.info/www/bejne/oZa1kp1qfN6ca7s Again, thanks for the nice comment, and thanks for the subscription. I'm happy my video was helpful.

I keep hearing about making it a floating neutral. Can i not plug into my transfer switch as is, without changing it over to floating neutral? That part is confusing.

[@SlipFitGarage]

Hi, you CAN physically plug into your transfer switch with a generator that has a bonded neutral, but your shouldn't. This is a copy/past from a reply that I typed a while back to another person who had a neutral bonding question under this video.... The way I understand it is...... if you're using the generator by itself and plugging directly into the generator outlets, you want the generator to have a "bonded" neutral so the breakers can trip when there is a fault. It needs that return path for the breakers to function properly. However, if you're using the generator to power the entire electric panel within a house (like I plan to do) then you want a floating neutral because the "bond" actually takes place in the main electric panel in the house. You only want an electrical system to be bonded in ONE place, and in the case of powering an entire house electric panel, that "one place" is inside the main panel of the house. (and NOT inside the generator) So essentially I will still have a "bonded" neutral when powering my entire house, except the "bond" happens in the electric panel, and NOT in the generator. If you have the system bonded in more than one spot, you can potentially be sending neutral current on BOTH the neutral conductor AND the non insulated bare copper ground conductor. The bare copper ground conductor is not intended to carry the "neutral load" full time. It's only intended to carry fault current long enough for the breaker to trip. Look at it this way..... The power comes into my house from the power company with three heavy conductors, two hots and one neutral. There is no such thing as a ground conductor supplied from the electrical company. The grounding system in a home originates at the main panel AFTER the electric meter. Anything before the meter has no ground at all. So, now think about powering my panel with the generator..... If the electric company doesn't supply a ground to my house, why should the generator supply a ground? It shouldn't. The generator will still be grounded because the main panel in my house will be supplying the ground TO the generator, instead of the generator supplying the ground to my main panel. Floating neutral when supplying power to an electrical system that is already bonded. (a house main electrical panel) Bonded neutral when using the generator all by itself, NOT feeding an electrical system that is already bonded. I added a power inlet box to the back of my house so I can easily connect my generator to my main panel during power outages. I pulled an electrical permit from the city and had the installation inspected by our local electrical inspector. Our electrical inspector has also been one of the main electrical instructors at the biggest name tech college in the state for the last 18 years. He inspects this stuff every day, and also teaches it. I specifically asked him about "bonded" or "floating neutrals" when powering my house and he confirmed what I just typed above. Be sure to check with your local codes and regulations. Do NOT take what I have typed above as fact. I am NOT an electrician by trade. Codes and regulations can (and do) change from area to area. I hope this help clear things up a little bit. Thanks for your comments.

[@rj5403]

Did you remove bonded neutral wire b4 connecting to your house panel?..I'd you power hse through 50 amp plug?

[@SlipFitGarage]

The neutral bonding wire inside the generator DOES INDEED need to be disconnected when I am feeding the entire panel in my house. I have not done that yet. I plan to do it soon. I've already watched the video to see how it's done. Using the 50 amp plug wont give me anything other than MAYBE an extra 1.6 amps of power. Just because the generator HAS a 50 amp plug does not mean it puts out 50 amps. This is a 7600 running watt generator... divided by 240 volts gives me 31.6 amps. That's all the generator can put out regardless of plug style. Thanks for the comment.

[@woody4u247]

great video, I've got the "Tool Store" 3500w one but I've been researching a bigger one with 240v for my needs, all I've found was the old fashioned noisy lawnmower Loud generators. Being an inverter style while still having 240v 50A outlet is just what I've been searching for! The remote start is a cool feature. it would be nice if it was a full 50A, but I'll sacrifice a few amps for half the noise & a Clean sine wave output! They seem to have thought this out, BIG gas tank so it'll run a good time, a load meter & a nice battery quick disconnect. even flip up handels to move it. This size genny isnt cheap so its nice to see a steel cage/bar so i can secure it so it stays mine! My neighbor bought an EV... I'll wait for him to run out of charge & I'll hafta go rescue him since this will do level 2 charging...lol..

Thank you for doing this video. This is very thorough AND including the shipping info! I also enjoyed the oil change video you did on this machine along with the break in oil and the drain hose. I'm just a little nervous about the long term dependability. Please re-post if you have any problems. I may order one in the next couple weeks. You're a good man and keep up the vid's. Just subscribed!

[@SlipFitGarage]

First of all... thank you for the compliments. 🙂 Not only did I buy the Genmax 9000, but a good friend of mine also bought the same generator about a month after I did. Granted, neither generator is even 1 year old yet, but I can say both generators have performed flawless since we bought them. My friend uses his generator to perform mobile electric vehicle charging, which puts a pretty sizable load on his generator the entire time he's charging an electric vehicle. So far, they have both been excellent. I will be sure to post here in this comment section if we have any trouble in the future. Thanks again!👍

[@sweetsuccesstrading5097]

Just caught your Video today, and will receive the Generator tomorrow. And just saw that they Have a New 10500 Tri fuel coming out Soon, with a Full or better 50 Amp

[@SlipFitGarage]

How long did you wait for delivery? Yes, I saw the new 10500 tri fuel.... I also heard they are coming out with an even larger inverter generator with a twin cylinder engine. I'm waiting to see what that is going to be. Thanks for the comment.

[@projectswithjw]

Nice video. Do you still like the genmax 5 months later?

[@SlipFitGarage]

Yes, I do.... I have only used it once for a few hours but it performed perfectly. It has given me no reason to NOT like it. Knowing that I will easily be able to power pretty much everything in my house along with keeping the oxygen concentrator running for a family member during power outages is fantastic. Sure, I could technically get by with a smaller generator but there is also something to be said about NOT running any piece of equipment near, or at it's engineered peak for long periods of time. If I was running a 3500 watt generator (for example) near it's rated running watts of 3000, that is relatively "hard work" for that machine. Now, running 3000 watts from my Genmax that is rated at 7600 watts continuous, that is "easy work" for that machine. Anytime you run any machine near it's engineered limit for long periods of time you can (will) easily shorten it's life expectancy. My Genmax 9000 should have a long easy life powering my house during outages. In fact, most of the time, the Genmax isn't even at full throttle while powering my house under normal loads without the A/C running. It's nice to have a generator that stays in "eco mode" (low engine RPM) while doing it's job 90% of the time. Thanks for the question.

[@Figure99460]

Hi Brian - Good video, very informative. I'm currently considering this generator or the Duramax version for occasional home backup (Duramax is on sale now and is about $200 cheaper than the Genmax), but don't like that the warranty is only one year compared to duramax's three years. Reading some reviews online also suggest that duramax's warranty and customer service are much better. Amazon offers a third party warranty, resulting in the Genmax costing about $350 more currently over the Duramax. Also, according to the only fuel consumption statistic I can find for both is for gasoline at 25% load - Duramax 20 hrs, and Genmax 14.5 hrs. It's hard to believe the duramax would be that much more efficient based upon how similar they are? Anyway, I primarily like the fact that the genmax has oil filtration, better cooling (in theory), and exhaust in the rear. The 50 amp receptacle does not matter much to me based upon my use case. Are there any other advantages to the Genmax you're aware of not covered in your video?

[@SlipFitGarage]

Hello, I had another viewer send me an email asking specifically about the oiling system. He wondered how there could be an oil screen/filter if the engine only had splash oiling, as mentioned on the factory spec sheet.... which I was also wondering myself.... He said that he called Genmax customer service and he was told that it was splash oiling. However, the customer service agent was probably reading the answer off the same factory spec sheet that anyone can see for themselves on the internet. Then, he received an email back from the factory in China saying that it does indeed have FORCED oiling (oil pump). Long story short, I was contacted by Genmax after I made my youtube video so I now have a personal contact within the Genmax factory. I emailed that person at the factory and asked them to specifically ask an engineer about the oiling system inside the Genmax 9000. I also told that person that we suspect their advertising material that says "Splash oiling" is printed wrong. The factory rep replied with this info.... This is a direct copy/past from their reply email to me. Please keep in mind this is translated from Chinese to English so it doesn't read 100% correct but you will get what they are saying: Hi Brian, The GM9000iED is mainly Forced oiling, only the camshaft is splash oiling! So our engineer told this system is the most updated engine function in the market! Pls help to explain with customers! We will edit our advertising material accordingly! Thanks a lot! As for other advantages... I am pretty sure that I covered all the advantages that I know about in my video. I really do not have any more info to offer. To me, having oil filtration, even if it's just a screen, it a huge deal. It's a long story but I have an old connection to the filtration industry, and filtration testing, and I can confidentially say that filtration is the key to engine longevity.... Air, fuel, and oil. ANY filtration is better that none. Also, the fact that it has an oil pump is also a big deal in my head. That fact that you can pump engine oil all the way to the top of the engine (valve train area) is great. It's pretty hard to "splash" oil all the way to the top of an engine, then get it to splash between two moving surfaces. ( between rocker arm and valve stem, for example) But that's not problem with an oil pump! I do not own a Duromax so I can not give you an accurate comparison. I am sure it's a great machine. And lastly, I am PRETTY SURE all the 9000-9500 inverter generators of this style (Predator, Genmax, Duromax, etc) are made in the same factory in China by the same company. It's called Dinking Machinery. But do not quote me on that.... Thanks for the question.

[@Figure99460]

@@SlipFitGarage - Thanks for the response. Good to know about the oiling system - I agree it’s an advantage over other similar models. I e-mailed the factory earlier today to ask about the (lack of) efficiency specifications…. Specifically if they know the propane efficiency at 25% and 50% load to compare to other models. I did notice their website no longer specifies the 14.5 hrs of runtime ay 25% load on gasoline spec, so hopefully they realized that is probably an error. I’ll post their response.

[@Figure99460]

@@SlipFitGarage - I received a reply from Genmax regarding the efficiency, pasted below… it’s somewhat surprising in that on paper it’s much less efficient than the duramax, which is hard to believe. For 25% and 50% loads on gasoline - Duramax: 20/11 hrs. Genmax 14/9 hrs. From Genmax: 25% and 50% load on gasoline, if the fuel tank is full with 26L, the running time is at least 14 hours and 9 hours. 25% and 50% load on propane, the LPG consumption is 0.95kg/H and 1.35kg/H, so you can according to your LPG tank capacity to calculate the running time.

[@SlipFitGarage]

@@Figure99460 I find that big of a difference hard to believe. Either the info for the Genmax is wrong, or the info for the Duromax is wrong, or maybe even both. lol. Just like the Genmax advertising material was wrong when it said the engine has "splash" oiling, when in reality it does indeed have an oil pump. It takes one horsepower to make (roughly) 746 watts of electricity, I have a hard time believing that either the engine design, and/or the generator head design on the Genmax is that much more inefficient that the Duromax. I don't know, It's hard to say for sure.... You should buy the Duromax and see how long it runs on 50% load.... and I will do the same with the Genmax. Of course weather conditions such as humidity and altitude will affect our test results if both generator are not tested in the same conditions. For me, I honestly don't really care about efficiency NEARLY as much as reliability. I'm not running my generator on a daily basis to run an off-grid homestead (for example), I'm using it mainly as a home backup generator. In my area we can go YEARS without losing power at all but when we do, it can be for a few hours, up to a few days. The longest we lost power was in the late 90's for 5 days after a major storm (they called it a "100 year storm") Our old grid in this area has NOT been improved since then so it could certainly happen again, but not likely in my lifetime. Our standard outage last between 4 hours to 2 days, at most. If your figures above are correct, the little bit of extra fuel I will use in my Genmax over using a Duromax is negligible, in my opinion anyway. (I'm sure a mathematician could calculate the exact difference for any give length of time. lol) If I ran it every day, sure it might become a concern, but it's not even a thought in my mind for the little bit I plan to use it. I keep 50 gallons of pure gasoline (no ethanol added) stored in 5 gallon containers that I cycle through every year or so to keep it fresh. If I lose power, I have plenty of gas here to get me through for a while. I figure, if we lose power, so did the local gas stations and they wont be able to pump gas out of their tanks so I better have gas on-hand or I'll be screwed. My Genmax is also a dual fuel machine from the factory so if I had to I could probably convert it to run on natural gas. I have a tri-fuel conversion kit here (still new in the box) for the 9500 Predator that I can probably use to retrofit onto the Genmax if needed. One way or another I can figure out a way to run my Genmax on natural gas. Of course, I could always buy a propane tank to have in my yard just for the Genmax but it would stick out like a sore thumb considering nobody with 75 miles (or more) in any direction has a propane tank in their yard. lol. However, that doesn't mean I haven't considered buying a 100 gallon (for example) propane tank just to keep in the shed to use as a backup to my backup. I currently own three generators.... The Genmax 9000 inverter. a Generac 7500 open frame tradition generator that's only has about 8 hours on the clock, and a Predator 2000 inverter generator. I like knowing that I have three generators, and three different fuel sources. Overkill? Probably. But this didn't happen overnight. Between camping trips and wanting to be self sufficient during natural emergencies it kinda just happened over the last 20 years, give or take. Anyway, bottom line for me is to keep the power on during outages..... fuel efficiency is very low on my priority list. Oh, and lastly, I should say that as of probably 6 years ago I now have a family member here at home that needs electricity 24/7 for medical reasons..... and that is probably why I have added redundancy to my electrical backup program. I don't blame you for considering efficiency.... There is nothing wrong with wanting an efficient generator. Everyone's situation is different. Again, thanks for the comments. 🙂

[@Figure99460]

@@SlipFitGarage - I agree, something doesn’t seem right with the numbers from Duramax, GenMax, or likely both. I followed up with Genmax for further clarification, but have not heard back yet. I think the predator 9500 specified efficiency is similar to the Duramax, so in theory you could compare the predator to the Genmax. Regardless, you make a good point about comparing reliability to efficiency… like you, it’s unlikely I will need the generator overly often for home back up, but when I do, I definitely want it to work! On average, we lose power 2 to 4 times per year ranging from 30 minutes up to 12 hours, rarely. We have a large buried propane tank so likely we will always use propane unless absolutely necessary. At this point I’m more curious than anything just to understand how two generators very similar to each other likely made in the same factory could be so different regarding efficiency. In reality I suspect they are very similar, but I’d still like to understand what the real numbers are.

Should be PLENTY of power to run the blower motor in your gas furnace and a BUNCH of lights..... along with a television, internet modem and router, washer and gas dryer, refrigerator etc, etc.

[@patrickcoleman5867]

Did you leave your generator bonded or un bond it im not sure I should do it

[@SlipFitGarage]

This generator comes with a bonded neutral..... and for running my entire house I really need to disconnect the bond inside the generator. I have copied and pasted below a comment that I typed to answer someone else's question in this same comment thread. This should help you understand: The way I understand it is...... if you're using the generator by itself and plugging directly into the generator outlets, you want the generator to have a "bonded" neutral so the breakers can trip when there is a fault. It needs that return path for the breakers to function properly. However, if you're using the generator to power the entire electric panel within a house (like I plan to do) then you want a floating neutral because the "bond" actually takes place in the main electric panel in the house. You only want an electrical system to be bonded in ONE place, and in the case of powering an entire house electric panel, that "one place" is inside the main panel of the house. (and NOT inside the generator) So essentially I will still have a "bonded" neutral when powering my entire house, except the "bond" happens in the electric panel, and NOT in the generator.

[@stevenlord6120]

Brian, what was your break in procedure?

[@SlipFitGarage]

It's still not 100% broke in yet but I ran it with varying load between 1500 - 4500 watts for the first 2+ hours, I also ran it with varying RPM by cycling the ESC switch on/off every 10-15 minutes. I am going to change the oil now (right around 2.5-3 hours, currently) to flush any metal shaving that are probably inside the engine from the manufacturing process. Then I will run it again for another 2.5 hours roughly with varying load to finish breaking it in. I believe the owners manual specifies a 5 hour break-in period. I am also using "Royal Purple engine break-in oil" for the first and second oil fills. Is that required? No. But engine "break-in Oil" has high levels of Zinc and Phosphorus which has pretty much been removed from most other modern day engine oils. The high levels of Zinc and Phosphorus help to protect flat tappet camshafts during the break-in period and also really help engine piston rings to seal against the cylinder walls. I will run standard engine oil after the break in period is over. Again, break-in oil is not required by the generator manufacturer but I think it's good insurance...... at least for me, anyway. Thanks.

[@watchman1982]

Is there a way to adapt this to natural gas instead of propane?

[@SlipFitGarage]

I can't give 100% specific instructions but one thing you would need for sure is a Garretson style low pressure regulator for NG conversions. This device helps to adjust gas flow to match engine load and speed. The device also requires engine manifold vacuum in order for the NG to flow into the carburetor. Without this type of device, if the engine died, the NG would just keep freely flowing and the air in the surrounding area around the generator could eventually become saturated with enough NG to become an explosion hazard. There are probably other small thing that need to be done but a Garretson style low pressure NG regulator is the absolute most important. Trying to do a NG conversion without the proper regulator is VERY dangerous.

[@lyleallen1579]

@@SlipFitGarage I understood (perhaps incorrectly) that the energy difference between these two would often be compensated for by changing the jets in a carburetor. But if this is using fuel injection then pressure would be the obvious way to attack that problem.

[@SlipFitGarage]

@@lyleallen1579 When you say "energy difference" are you talking about the difference in energy that different fuels make when burned in an internal combustion engine, or are you talking about the difference in energy that generator itself is capable of putting out when running one different fuels? Either way, this is how I see it.... one horsepower is equivalent to 746 watts of electricity..... So if your engine is down on horsepower because it's burning a fuel with less energy potential, (BTU) then the overall output of the generator will also be down. Does that help with your question? I'm certainly not an expert on different types of fuels.... I get just the basics.

[@Mamun1266]

Can you place this inside house or garage?

[@SlipFitGarage]

Absolutely NOT! The gas engine produces deadly exhaust fumes just like any other internal combustion engine. DO NOT put this in your house!!! The carbon monoxide will kill you and anyone else in your house. NO you CANNOT put this inside..... or ANY OTHER gas or diesel powered generator. A generator with an engine is NEVER allowed to be in your house. Ever! NO engine driven generator ever made, regardless of brand can ever be located inside your house. There is no exception. NO!

[@laz288]

I really like GenMax units but time will tell on service. The tool store gens have locations all over the country and always try to make sure the customer is happy. On Amazon out of 432 reviews for Genmax as of today, 20% of those is 1 star due to issues and poor customer service. Once the tool store ups it 9500 model with dual fuel and al the new features I think GenMax will have to step up and offer better service and parts. But as I said I do like the Genmax Units.

[@SlipFitGarage]

I understand what you're saying but keep in mind, very few people go out of their way to write a positive review. Only when they had a bad experience do most people spend the time to write a negative review. The total number of reviews on Amazon COULD be 3 - 4 times that number of people who had a great experience and never took the time to write a review at all. I say COULD because we have no way of knowing. We also have no way of knowing if those negative reviews are from people who legit had a problem with the Genmax product, or was their trouble caused because the user had absolutely no idea what they are doing to begin with and caused the problem themself? I've also seen MANY, MANY people give bad reviews on Amazon products because of shipping issues. (for example) Or Amazon customer service issues. The product may be excellent but they write bad reviews for other aspects of the purchase and the product takes the hit with a negative review. Sure, I look at reviews, but I don't put much faith in them. There are a LOT of people in this world that have very little to no mechanical ability whatsoever and those people write negative reviews when they get confused.... which happens easily. I'm not saying all of those reviews are bogus, some of them area real, for sure..... but not all of them. On a side note, I just read somewhere that there is now a US based Genmax customer service/repair center here in the USA and they stock service and repair items for Genmax equipment. I believe they have an 800 number and if I'm not mistaken, it is located in either Phoenix or Tucson. If I find that info again, I will post it here for you and anyone else who reads this comment. I personally own two Genmax generators and a friend owns one (another 9000 dual fuel) and the only problem with all three of them has been the remote start FOB on my friends 9000 watt will not start his generator, but it will shut it off. Otherwise all three have worked perfectly. (although my second Genmax is only a few weeks old at this point) Bottom line, just like anything else, there is always two sides to every story and we're only getting one with on-line reviews. Don't ignore them, but don't believe all of them, either. Thanks for the comment.

[@laz288]

Totally agree 100%. People with zero mechanical knowledge could make a perfectly fine gen not run due to some simple issue. I have 2 predator 5000s and plan to buy the Genmax 10k tri fuel model. I did hear they have a parts and distribution center also, San Diego or AZ (not sure). Those who break in their engine correctly, oil and clean the filter, clean the spark arrestor, use a magnetic plug, fuel stabilizer, typically eliminate so many issues right of the bat. IMO all GenMax needs to do is provide a comprehensive parts list and availability and they would easily compete with HF on customer service/repairs. @@SlipFitGarage

[@1new-man]

Sir does the Genmax 9000ied come with a floating or a bonded neutral? TY

[@SlipFitGarage]

The Genmax GM9000iED has a bonded neutral from the factory. There is a video on KZbin that another guy did showing how to disconnect the bond wire on this particular generator if you want it to be a floating neutral. However, I believe the process in his video makes it much harder to disconnect the bond than it needs to be. I believe there is a much easier way but I have not gotten that far yet with my generator. Personally, for my setup, I want a floating neutral. When I get around to disconnecting the bond wire on my generator, I will make a video about it. Stay tuned for that video. I also have several more Genmax 9000 videos currently in the works. The next one will be about how I plan to quiet the exhaust noise. Even though this generator is VERY quiet, I want the engine exhaust sound to be even quieter. My plan is a little different from what others have done to quiet the engine exhaust on their portable generators here on KZbin.

@@SlipFitGarage Ty for the reply. When interchanging 50 amp generator home service verse job site extension cord service I understand there is grave concern regarding "Electrocution" or potential house fire caused by an improper grounding relationship between the breaker box and inside the generator. Things that are different are "not" the same; and must de addressed accordingly. No clear understanding for average Joe here but I do "Know" everything I have viewed on YT scarcely addresses the importance of compatible grounding and why "floating" neutral is not safely compatible with "bonded" neutral. The one cancels out the other.and it matters greatly. Your comment is encouraging. Again TY so much for your kind reply Have a great day! Psalm 118:24

[@SlipFitGarage]

The way I understand it is...... if you're using the generator by itself and plugging directly into the generator outlets, you want the generator to have a "bonded" neutral so the breakers can trip when there is a fault. It needs that return path for the breakers to function properly. However, if you're using the generator to power the entire electric panel within a house (like I plan to do) then you want a floating neutral because the "bond" actually takes place in the main electric panel in the house. You only want an electrical system to be bonded in ONE place, and in the case of powering an entire house electric panel, that "one place" is inside the main panel of the house. (and NOT inside the generator) So essentially I will still have a "bonded" neutral when powering my entire house, except the "bond" happens in the electric panel, and NOT in the generator. If you have the system bonded in more than one spot, you can potentially be sending neutral current on BOTH the neutral conductor AND the non insulated bare copper ground conductor. The bare copper ground conductor is not intended to carry the "neutral load" full time. It's only intended to carry fault current long enough for the breaker to trip. Look at it this way..... The power comes into my house from the power company with three heavy conductors, two hots and one neutral. There is no such thing as a ground conductor supplied from the electrical company. The grounding system in a home originates at the main panel AFTER the electric meter. Anything before the meter has no ground at all. So, now think about powering my panel with the generator..... If the electric company doesn't supply a ground to my house, why should the generator supply a ground? It shouldn't. The generator will still be grounded because the main panel in my house will be supplying the ground TO the generator, instead of the generator supplying the ground to my main panel. Floating neutral when supplying power to an electrical system that is already bonded. (a house main electrical panel) Bonded neutral when using the generator all by itself, NOT feeding an electrical system that is already bonded. I added a power inlet box to the back of my house so I can easily connect my generator to my main panel during power outages. I pulled an electrical permit from the city and had the installation inspected by our local electrical inspector. Our electrical inspector has also been one of the main electrical instructors at the biggest name tech college in the state for the last 18 years. He inspects this stuff every day, and also teaches it. I specifically asked him about "bonded" or "floating neutrals" when powering my house and he confirmed what I just typed above. Be sure to check with your local codes and regulations. Do NOT take what I have typed above as fact. I am NOT an electrician by trade. Codes and regulations can (and do) change from area to area. I hope this help clear things up a little bit. Thanks for your comments.

@@SlipFitGarage You are correct on the neutral. I have to say, the process of changing from bonded to floating neutral shown in the vid on the GENMAX site is actually very easy and took me all of an hour.

Try the 50 amp plug to power whole house..thnx

[@SlipFitGarage]

This is a 7600 running watt generator... divided by 240 volts gives me 31.6 amps. That's all the generator can put out regardless of plug style. The Power inlet box on my house is connected to my main panel via 10 gauge copper THHN wire and fed through a 30 amp breaker. I see no need to size my power inlet system for 50 amps when I do not own a generator capable of supplying 50 amps. Also, with every light turned on in my house and garage, along with my driveway flood light and front door light, with my central A/C and refrigerator running, my 55" TV turned on, an oxygen concentrator running, my internet modem and router along with my desktop computer and monitor running..... basically EVERYTHING running in my house EXCEPT for a toaster and a microwave.... my entire house only draws around 3200 watts. (it's a small house with gas appliances) That is less than half of the 7600 watts (31.6 amps) that my generator is capable of putting out. Less than half. I see absolutely no need to rewire my power inlet box with 6 gauge wire and install a 50 amp breaker in place of my existing 30 amp breaker. That would be a 100% waste of money for absolutely zero gain..... in my opinion anyway. Maybe some day if/when my power requirements increase, and I either buy a larger generator, or another Genmax 9000 to parallel with this one, then I might consider upgrading my setup but there is no need for that now, or in my foreseeable future. Thanks for the comment.

[@hotnics]

I have the 9000ie and it has never run right from the first start. I hope to fix it but it's out of warranty and the customer support doesn't respond anymore and no service shops in the US. Something to keep note of. I got it for free from Amazon because I could never get it to work right and they don't accept returns in generators once gas is in them. That should tell you something. I'll get it to work one day but I had to buy another generator that actually works. YMMV

[@SlipFitGarage]

You mention in your post that you got it for FREE from Amazon because it doesn't work right. So, basically Amazon already refunded you for the problem?.... And now you want to talk bad about the generator that you've already been refunded for? Yes, that DOES tell me something..... That I really have NO WORRIES about buying anything from Amazon because they will make it right for me. (or any other customer) My mileage DID vary.

[@hotnics]

@@SlipFitGarage yes Amazon not Genmax. Are you paid by them? There is zero support in the US.

@@hotnics No, I am not paid by anyone! And you are wrong.... there is support in the USA.

@@SlipFitGarage great thanks because it's been radio silence for me. I'll try the info you have. Take care

[@SlipFitGarage]

I wouldn't be surprised if they're not willing to provide support or replacement parts for a generator that has been refunded. Yes, I get that it was refunded by Amazon, (not Genmax directly) but Amazon WILL get their money back from Genmax. Amazon has a warehouse full of Genmax products and they handle sales transactions for Genmax every day. Nobody gets to keep selling products on the Amazon website if they owe Amazon large amounts of money. Genmax is not an exception to the rule. In fact, I'm willing to bet the refund money that Amazon gave to you was immediately withheld from Amazon's next payment to Genmax. Amazon does NOT just keep eating losses like this from the thousands of private sellers on their website who won't honor the return policy. lolol. They get their money back every time. Eventually.

[@jamesfranze5276]

Have more than one series of this GM 9000 been produced?

[@SlipFitGarage]

Genmax has 2 versions of this generator, the dual fuel like I have in this video, and the gasoline only version. However, there are several different brands currently offering 9000-9500 watt inverter generators.... Genmax, Predator, Duromax, AI Power, come to mind at moment.

[@DM-fp8uw]

If this was reliable and had any customer service whatsoever, it would be a great deal.

[@SlipFitGarage]

Do you care to share what happened to you with a generator like this? Otherwise your comment doesn't really mean much. It's just ANOTHER negative comment on the internet....

[@DM-fp8uw]

​@@SlipFitGarage Fair enough. I do not have a Genmax, but like every single Honda clone Chinese generator, they are ALL made by the same company that also owns Genmax, Chongqing Dinking Power Machinery Co., LTD. Whether it is Harbor Freight, Northern Tool, Duromax, Champion, or A-ipower etc. all are made by the same company with slightly different specs (which is why the Duromax 9000i and Harbor Freight Predator 9500 are nearly identical). Genmax is essentially the house brand for CDPM which is why you see a little more innovation with their generators. I have been scouring the internet for every Genmax review that I can find because this generator is exactly what I want (although a little noisier than I would prefer), the customer service in the US is not good at all. The best you can hope for is maybe them mailing you an inexpensive part to replace yourself. Since they are all made by the same company, the plus side to buying one of their generators made for Harbor Freight or Northern Tool, for example, is there is a store you can take it to for returns. But they have downsides as well such as needing to install a conversion kit for propane. Champion apparently has decent US customer service.

[@SlipFitGarage]

So you're posting negative information about a product and/or customer service from a manufacturer that you've NEVER personally purchased a product from, and have never personally dealt with their customer service? Um, okay.... lolol. Have you ever noticed that hardly ANYONE ever takes the time from their busy lives to write a GOOD review about a product or a company? Sure, there's a few positive reviews on the internet, but NOT many compared to the negative reviews. Half the negative reviews on amazon are from customers who have NO IDEA how to operate the product they purchased so they gave a negative review. Or the shipping sucked, so they gave a negative review, Or they though the item cost too much money so they gave a negative review, etc, etc..... Half (maybe more) of the negative reviews on the internet are from people who have a problem related to the product, not with the product itself. Now take into consideration what I said earlier about nobody ever taking the time to write a good review, along with half the negative reviews are bogus to begin with, and I am willing to bet Genmax isn't nearly as bad as you say it is..... Based on reviews alone. In fact I OWN one and I can tell you from personal experience that it's been great so far. Time will tell how long it will last but right now its been terrific. You're basing your personal opinion (which is totally fine) on negative reviews from strangers on the internet..... But don't turn around and write that opinion as fact somewhere else. It's simply your opinion. If you want Honda reliability, along with Honda service and parts availability, then buy a Honda. It easy, really. The problem is, people are now expecting Honda parts/service/reliability for Genmax prices. I have never seen an advertisement from Genmax where they have promised to be just like Honda.... and I don't expect them to be, either. And lastly, the fact that these are all made at the same Dinking Machinery Co. factory in China is no secret. Anyone who has researched these generators has either read that for themselves, or already assumed it strictly based on looks alone. They look too much like each other to NOT be made by the same company. Thanks

@@SlipFitGarage Even if I owned one and posted my own experience, it would just be a single data point. Reading a few hundred reviews on sites where they are sold gives you a much better data than one person's anecdotal evidence

What about all the positive reviews that WOULD be there IF people took the time to write those? Internet reviews are unreliable, at best. Sure, internet reviews are information to help make a decision... but it's not great information. None of this is relevant to you anyway..... you've already decided in the back of your mind that you won't be happy with anything but a Honda. By the way, how can my opinion be "anecdotal" but anyone with a negative review is somehow accurate? lol
