In the process of doing research for others, I've discovered that there are now over 1/2 dozen 240V inverter generators in the 5000W+ class:

Honda EU7000is $4500


Yamaha EF6300iSDE $3400






Powerhorse 7500i $3000



AIMS GEN6600W240VS $2000



Briggs & Stratton Q6500 $1200





Sportsman GEN85KIDF $1700



Champion 10051 $960

Which is going to be your next one, tabora?
With the speed things are changing, it'll probably be something else in the future... I've been watching for a good, used EU7000is for about a year, but all these new players have me looking at all the options. I really want the following features (just a matter of time, I think):

  • 240V up to 45A starting (my GenerLink maximum)
  • Inverter <5% THD
  • Electric Start
  • Auto Choke
  • Remote Control for Start/Stop
  • Monitoring via smart device if possible, including oil level, fuel use and run timers
  • 60db or less
  • Dual Fuel preferred

Yep. Inverter is the way to go. 240 @45 amps is enough for both convenience and comfort. I sometimes marvel at what I can do with just the 3000. The 7000is would be sweet and most satisfying for guys like us. You can get those remote options you want, too. Pinellas Power, for one, has key fob-type and smartphone remotes. He's pricy, but his stuff is pretty neat.

I was in your same shoes for a while, I just recently pulled the trigger on a new eu7000.

The Eu7000 ef6300 and powerhouse 7500 are the only three real contenders in the space in my opinion. The 7000 seems to offer the best of everything except the price....

I’m going to install uscarbs new trifuel kit, a wireless remote start and build an updated generator shed. With a soft start I’m confident it’ll run my central air and be a nice compromise to a standby generator, with Cleaner power, more versatility with fuels, maintain portability, and ease of operation for my wife if I’m not home.

well as a Honda eu7000is owner (several of them)
they are a bit of sticker shock for the guy who does not have any bucks..
but... it is an investment...
and a real good one at that!!
yup the tri fuel kit looks good!!
I have pix of them on the honda forum.
as well as links for the kit.
right now the tri fuel kit is less than 500.00.
and you will need a few hoses and a lp regulator that are optional as every one may need different hose lengths.
natural gas is my choice for primary gen fuel..
but I have the choice of unleaded gasoline and Liquid Propane as well as a choice.

severe wind and earthquake can take out the natural gas... or lp if your property has a direct hit!!
and floods will float lp tanks...

over plan your system!!
and if you are doing a gen shack make sure you have proper vents and sensors for lp, ng, gasoline!!
I prefer cement block shack with a faraday cage.
and you can clad the outside with tin as well.
and a heavy steel door with real good locks to keep it safe!!
we use 12 volt and 120 volts for our vent fans...
and have a start shut down delay if the pel level is high on gases inside the shack.
and auto fire control drops.

If I had the money I think I would go for a powerful quiet inverter gen aswel, as my 2800watt is rather on the loud side and the bigger you buy the louder it will be. But on the other hand if you go for a open frame normal gen with advanced AVR power performance to make it act like a inverter gen, you could go much bigger and spend the same kind of money.

The AIMS Power looks like a contender to me, as well... From their About page:

At AIMS Power, our mission is to be leaders in the design and development of off-grid and renewable energy.

We sell our signature DC to AC inverters, solar panels, deep-cycle batteries, solar charge controllers and more to some of the most innovative companies and organizations across the US and worldwide. What’s more, we strive to provide the best quality products and unbeatable customer service and tech support to match.

The story of AIMS Power...

The first AIMS Power inverter was created in 2001 by founder and president Bruce de Jong in his Reno garage, Nevada. Our president devoted late nights to developing truly unique inverter designs and researching the needs of the renewable energy markets. And he succeeded.

Armed with just a college degree and a little business experience, AIMS Power was born, designing, developing and bringing to market the most extensive line of inverters available.

The company was eventually able to move to an office in South Reno, before expanding to two facilities. A business of one grew with the addition of de Jong’s wife Laura, followed by a staff of just 14. Sales, marketing and warehousing teams and specialists would be the next additions, helping the company go from strength to competitive.

I just looked at the manual for that unit...
2x on the 3 phase windings cool idea!
where are they mfg the gens at?? what country??
is this a chonda clone engine?? looks like a gx390 by the specs...
I would still say the eu7000is is better... the injection has it for me!!
way better on run time!!
and starting during the cold as it is injection it over fuels during start!!
cool item!!

the one thing about the AIMS company is they are making or doing the design on grid tie systems...
now if they have this all worked out so the aims gen can work along the side a solar system inverter as a tie..
yea this could be huge!!
I would take the time to call them and make a list of good questions!!
and where are the mfg plants?? usa?? what parts are they using? japan or china?:tango_face_grin:

The aims 6600 is surely a Chonda engine but that’s not nessesarily a bad thing, most clone motors have proven to be Very stout. My question is the longevity of the stator and inverter. 240v inverters have to be able to support lots of return current on the neutral circuit which can cause harmonic distortion and reduce the life of the component. On the other hand the Machine is only $2000 bucks, and if parts are readily affordable and available... then give it shot.

I would be great to hear a matter of fact review of it.

me too!!
I have seen some chondas still running after 10 years on log splitters!!

I agree... not all inverters and inverter gen windings are the same...

now that is an idea!!
honda and the other close brands need to make an replacement inverter head!!
you just bolt it up to your engine and the head has every thing else self contained!!

and all of them need to make an 20-25kw inverter gen!!

right now we are doing 2 of the eu7000is units in parallel for 12kw rated.

lol the china and japan folks are thinking "what do they need with all that power!!"
they think the eu2200i is a big gen set!!
and if you are in one of the cracker box places yea a 1500 watts will run most of the appliances over there!!
but down south the inverter air conditioning units zap more that that!!
for me I would have to have air con to get rid of the humidity!!
heck I have the dehumidifier on right now!!
lower the water in the air, the more o2!! at least per cu foot!
