Paralleling Portable Inverter Generator: GENMAX GM9000iED & GM9000iE (Load Test Review)
Description: (copy and paste the below into your video description)
What do you get when you parallel 2 GENMAX Portable Inverters? Does the GM9000iED and the GM9000iE holdup to their 7200 watts ratings? As always, I give my straightforward opinion on performance. Highlighting “what’s good” and “what can improve” from my experience after load testing the two generators, just in case you’re looking to purchase a portable inverter generator as a backup generator for RVing, homesteading, or emergency power outage.

// DETAILS
Let’s check out the GENMAX 9000iED and the GENMAX 9000iE, two powerful portable inverter generators capable of maximum power with minimal noise. They are EPA-approved but not carb-compliant, so you can’t purchase them in all states. But they are suitable for forested areas.
Two impressive portable inverter generators.
// EXPECTATIONS
The GENMAX 9000iED Dual-Fuel Inverter Generator is rated for propane gas output of 7200 watts, and the gas version is rated for output of 7600 watts. No worries, the 400 watts difference is no big deal. And since this generator is parallel capable, you can connect multiple units for more power!
The GENMAX 9000iE (gas version) has a rated wattage of 7600 watts. Parallel capable. I expect that there will be no surprises during this load test, and both generators will perform as rated.
Specs:
GENMAX 9000iED:
Running watts – 7600 watts
Run time – runs up to 14.5 hrs. at 25% load
Weight- 233.7 lbs. (this bad boy is heavy)
Noise – 62 dBA (pure Sine Wave output; one of the lowest)
Consumption – 0.48GPH at 25% load
GENMAX 9000iE:
Running watts – 7600 watts
Run time – runs up to 14.5 hrs. at 25% load
Weight- 233.7 lbs. (this bad boy is heavy)
Noise – 62 dBA (pure Sine Wave output; one of the lowest)
Consumption – 0.48GPH at 25% load
// USER EXPERIENCE - Load Test
The GENMAX 9000 closed frame design looks good, yet it’s rugged enough for RVing and other outdoor activities. After a few simple tests, I paralleled the GM9000iED and the 9000iE together to test their overload capacity. Mission overload.
I used my RV to push overload and used the Power Watch Dog 50-amp Surge Protector by Hughes Autoformers to monitor the readings from inside my RV.
What’s Good: both units put out incredible pure sine wave power! The GENMAX 9000iE has all the features as the GENMAX 9000iED minus the fuel selector switch. Both are remote start.
The GM9000iED has a great feature that allows you to switch from propane to gas without shutting off the unit. It also drains your carburetor. Now that’s a valuable feature for storage. Simply turn off and wait for the gas to run out of the carburetor. Now, if you’re anything like me, you’ll go the extra step to preserve the unit and drain your tank. Coming soon - video showing how.
Another added feature of the GM9000iED is its 50-amp plug makes it easy to parallel without needing other hardware.
What Can Improve: technically, these are “portable” generators, because each weigh around 233 lbs. They are not going anywhere quickly, but they do have rolling wheels.
// TO SUM UP
The GENMAX 9000iED & 9000iE paralleled together to produce some serious power. My load test showed that nether generators sounded like they were forcing or struggling during this heavy load test.
If you decide to buy any of these generators, you won’t be disappointed.
GENMAX certainly took their time engineering this class of generators. They paid attention and corrected the shortcomings of the older designs, and these are the best in their class so far.

Just ordered one! I was looking at the predator but i really like the remote start and dual fuel. Thanks for making these videos they are very helpful.
-
Gavin - I really like this video great info. Using the Watchdog was interesting and a great new addition to your videos. I've been thinking of using one on my own setup. I just need to sell my loud open frame gen for a inverter. These videos provide lots of value to the RV community, campers, homesteaders, rural living, and power outage survival.
-
I bought one of these Genmax GM9000iED generator today after watching your video, Thanks!!
-
Well I was squarely in the Duromax camp until I saw this video. The ied has me sold. Thank you for putting the information out here like this.
-
Great review as usual Gavin! These inverters seem like the best design in their class so far
-
Well ! That’s the power of inverter generators these days . Great video and with them connected in parallel to get industrial power out of them to run the big loads . Awesome !😊
-
Interesting and entertaining video as usual. Someone else commented about the Hughes Watchdog. I think a lot of us would like to see an in depth video on that. I watched a couple of YT videos by others but I like your style better. 😉

This is the video I've been waiting for! I can't remember where, but I heard somewhere that the reduced power rating on propane was due to the tank getting cold and pressure dropping, so theoretically, if you had a big enough tank, regulator, propane hose, and or a tank heater, you could get the same power out of a generator as you can on gas. I'd imagine you have to run on propane for some amount of time before you can't make full power anymore. Anyway, thanks for the video! This answered most of the questions I had.
-
Nice one Gavin. Have a great Memorial day weekend.
-
Thank you. Answered all my questions.
-
Impressive generators and a great instruction, Gavin.
-
As always great video!
-
Great video G' Those are some big boy generator's. I'll take the dual fuel.
-
Nice job excellent video. Learned a lot
-
Great job on this video. Thank you!
-
Great Video!! Thank you much!!

Answer: Yes, the 50 amp receptacle and the 30 amp receptacle will need to be used at the same time to take full advantage of the power output available. Please note that any 50 amp receptacle will be limited to 12,000 watts at its peak capacity.
-
I would love to see a review on the 50 amp surge protector used in this video.
-
Very interesting. Its cool how you can parallel them together. I assume that they automatically synchronize phases? You could run an average size house on that. Great video!
-
Great video! Going to pick up a watchdog today! Have you done a test trying to run a residential AC/heat pump off one of these? I have a 2021, 3 Ton, Ruud, 17Seer, three-stage, inverter heat pump and I'm hoping I can run it and the furnace blower off this machine. Your thoughts?
