Recently purchased this after the Helena storm with a smaller generator just didn’t cut it. Looking forward to putting this beast to work or maybe not..don’t really want to lose power. I purchased this after a lot of research to insure I got the right one. Went with inverter as the standard generator is loud. This one has the 50 amp plug as I had added a plug and tied it to the breaker box with an interlock. Also having to find gas was a pain, so I am looking forward to getting the natural gas set up. One thing I did notice was that even though this unit comes with a 1/2 natural gas hose it has a 3/8 inlet connection on the generator for the 1/2 inch hose. I purchased a 3/4 hose and adapter for the 3/8 connection as I wanted to ensure flow was not a issue, maybe over kill.

This is great bang for buck buy, I don’t see anything else on the market that gives you more for your dollar than this pressure washer. I’ve had it for about 3 months now, broke the nozzle after a little bit , got a hold of the aupprt and they sent me all 5 nozzles again. No complaints

The GM5500XID has blown me away with how reliable and powerful it is. It starts up instantly, runs smooth, and handles everything I throw at it without struggling. The build quality feels heavy-duty, and the noise level is much lower than I expected for this size generator. I’ve used it for work, home backup, and even on the go — and it performs flawlessly every single time. Fuel efficiency is great, makes it super convenient. If you want a generator you don’t have to worry about, the GM5500XID is the one. Highly recommended!

Worst customer service I have ever delt with. On the phone for 35 min. and got cut off! On phone again talking and explaining my issue and they cut me off again after 30 more minutes!! Sams obviously has call center in India or somewhere. Horrible!! I won't be renewing my membership!!!!

I don’t normally leave reviews but this 10000w tri fuel is a game changer. I can use it to power my house, and it’s small enough to take with me for other projects around my property. Super easy to move around and relatively quiet for an open frame. I also like that it’s an inverter so I don’t have to worry about my devices being damaged. Love the 50A port- makes it easy to connect to my house

Wow! Genmax Nailed on this one – The tri fuel option is a must these days and I will never get a generator without out it. I did some shopping around and this was the only big wattage unit that came in an enclosed inverter while providing me with the running wattage that I needed to power my house. Ordered this unit back in June and the unit arrived at my house less than 3 days later- and the white glove service was impeccable. The guys unloaded the unit for me and dropped it off exactly where I needed it to go which was sweet, I was a little worried about maneuvering this beast but once it arrived the heavy duty handle bars and wheel system make it super easy to move around, youre carrying less than a quarter of the weight. I was looking at the Westinghouse unit which was a few hundred dollars more but was an open unit. The fact that I can keep this unit running outside indefinitely while having it connected to my natural gas line and have people over in my backyard without being disturbed was shocking to me.. the noise level is so low you barely notice it in the background. I also have been in talks with their support team about getting this unit connected with a transfer switch which I will be doing soon – Oscar and the genmax support team were awesome with answering all of my questions and getting back to me with emails – very happy with my purchase after 2 months of owning

I bought this after Beryl hit Houston and have since upgraded my gas lines and electrical to have the 50A available to connect. I pre-planned having this unit in parallel so if I do need a 2nd generator I can run these two together and get the full <3% THD at 12.5kW to my home which should be plenty. The unit is very well made, looks nice, and has incredibly low decibel noise compared to my neighbor's duromax open frame. It came with high quality spark plug (TKG) and a magnetic dip stick so both normal aftermarket swaps are already covered here. Draining the oil, changing the plugs/filters, etc. is somewhat difficult though because of the tight space inside the unit so be prepared.

Purchased the Genmax 11000 about 8 weeks ago. The Genmax arrived via a delivery truck and everything was in perfect condition. The generator was well boxed to ensure the product was not damaged. I was surprised how well made the Genmax is and think it will provided years of great service. We purchased this product as the emergency back up generator for our whole house. This handled our 5 ton air condition with no problems. We did have a soft start and interlock system professionally installed by the electrician. We live in the Houston area. Natural gas will be our preferred fuel source. Would like to see a custom Genmax dust cover included.

My wife gave me this as a Christmas gift and I just used it this week camping. I appreciate the durability this generator has. Was able to put it to use this week and I couldn’t be happier. Only thing I would say is that it is a little heavier compared to some other ones I’ve previously owned.

I only have 5 hours on it for the break-in so far. It doesn't come with the ATS cable, but I am not going to use that anyway. The air filter is really wedged in there, not the easiest to open and remove to get it oiled. Plus, the plate behind the air filter to the carb intake fell out and was a little difficult to get back in properly. The oil strainer is also a little difficult to reach. Other than that, it performed well on my break-in runs up to 4kw.
