Default Is Honda EU7000iS overkill for me? Inverter technology capped at 7000?

Anyone here have any recs for generator brands like Yamaha or are we all into the Hondas, or whether I should be concerned about the evolution of inverter generator technology? My use is mainly due to occasional power outages that might occur 1-2 times per year. The worst power outage in my area has been 5 days in length. (in addition to Hurricanes, NC is on the rain/snow line have terrible ice storms). I do have a 50 amp inlet that is connected to my house subpanel with an interlock switch.

At first I wanted a 12,000 watt generator (the CAT or DeWalt), but I guess I'm being too "high maintenance" and just want lots of power in case I needed it during an outage. I think an "inverter generator" is probably better, they are much more quiet and full efficient. Those 12k watt generators use a lot of fuel. I suppose a 5000 watt generator would do well and still run essentials, and even a portable ceramic heater or portable A/C unit if I watch the loads. Quiet, long-lasting and “toughness” are important to me.

Also, an inverter generator has more even sine waves and THD (total harmonic distortion) will be <5%, and even <3% for Honda units.

My dream machine is the Honda eu7000is - But that's at $3999! Does inverter technology not useful for loads above 7000 Watts or just too expensive to make? An advantage of the eu7000is is that it can handle more Watts than it’s rated for.

Most of us are into the Onan units round here. The older ones are built like sherman tanks. The next best and a little more complex would be the military generators or MEP units. Those things are darn near bullet proof.

Personally though I just have two gens. One of which I built myself and the other is a Coleman 4KW from the 80's or 90's. In the past 3 years I've only lost power long enough to run a generator during Hurricane Florence. 22 hours in the dark.

Inverter and drive technology are the same technology and they can be very large.
But a point comes when they are probably not any better than a simple conventional generator and they are definitely more expensive.

CAT or DeWalt do not make small generators everything you see with those names on it in small consumer units are probably just Chinese stuff you pay twice as much for based on a brand name.
Yes then tend to have longer warranty times, but you already paid twice as much if they have to buy you a second one...

I do see the advantages of the inverter generators but I don't think a Honda is worth what they ask for it.
Honda guys just pay it...
Like the Onan guys that think their stuff is the be all and end all.

Your best is consumer reports and long detailed investigation into what you need and what is the best choice for you.

I think simpler is better because everything breaks sooner or later.
What will it cost to buy, operate and eventually replace divided by years of service

Yup, I figured most all other parts are from other countries. The DeWalt DXGN14000 gets around that by advertising that it has a Honda engine.

In my case here in NJ the Honda EU7000 I find is the best choice. I live in a residential town and have neighbors on both sides. The EU7000 is very quiet and very fuel efficient. Parts are no problem to find. I can set it up very fast in the event of a power failure via the generator inlet box and interlock. When not in use it stays very comfortable in my garage out of sight and out of the weather.

HouseBuilder328-

If you really need the power, it is not over-kill. I have its predecessor, the EU-6500, which has served me well during hurricanes and Ham Radio Field Days.

But do you really need that much power? A minimum amount of lighting, Microwave Oven and refrigeration is all I really need. A smaller generator would have probably used less gasoline.

Reliability is the main value of generators such as the Yamaha and Honda inverters. But there are smaller models that may meet your true needs.

Most of the parts?
Try completely fabricated in China as contract engines and generators based on old Honda designs.

The advantage is most of the parts interchange with other people's generators.
This makes them very cheap to fix.

The design is based on a very sound Honda GX and brush type head.
My only beef is I think the Chinese could have improved them by making the connecting rods 1 inch longer and added 3 cooling fins

I have a very different idea about inverter generators.
i think they should be separate units to isolate the electronics from the engine.
The generator should be simple and stupid cheap too.
Buy a few batteries, add a quality inverter and a simple stupid battery charger to coordinated with them ( Solar or wind too for stationary applications )

I do not endorse this product I am simply making people aware of it.
Brushless and brainless with a PM head.
When it fails its dirt cheap to repair or replace the parts.

Thanks for the links. Those are some interesting bits of kit you've found. Too bad they are not turbine units though. Building a EV using standard DC components is on my bucket list. Will need a range extender for the lead acid batteries. Unless the lead carbon batteries come down in price I will be sticking with proven components. I am not a fan of lithium anything and wont be using any of it either.

This is really a personal preference for you. If the power goes out, do you need to run it all night? Do you have that much power need all night?
The honda inverter units are quiet, when I got mine (Honda EU2000i) it was the most quite I could find and that was the most important factor for my needs (Item #2 was the weight, I can load and unload it all by myself)
If you need more than 7,000 watts and want to keep noise down, I recommend the Multiquip whisper watt generators.

MQ power more made in China.
Not saying that is bad but don't fool yourself into thinking just because it says Kubota or John deere that its not.

My personal preference is for Chinese stuff that is a knock off.
You pay a lot more for a branded product and often are just buying a name.[

Those are cheap as hell to build and simple enough for anyone to fix.
For some reason you can not buy them here though off the shelf.
that Crazy everyone with an RV or off grid summer home could use something like that as a back up.

Turbines are fuel hogs.
The only time they are cost effective is if you have some use for the heat they generate.

This is something that looks so close to a GX design I think Honda will eventually sell them.
Then we have something that is a significant improvement in fuel consumption worth of an Inverter set.

I have three inverter units and a former Kubota powered light tower with a Stamford-Newage (genuine made in England) 4 pole 6000 generator.
The inverter units are a eu2000i over priced Honda, Boliy 3000 watt $75 craigslist special and a 1000 watt Champion Cheapo from Sam's that was too cute.

The Boliy is the quietest one with the Kubota powered unit a close second after adding a second muffler, weatherstripping around all doors and aspelt stick on sound deadening material on the inside of the cover.
At a solid real 6000w continuous runs everything I want to run.

Default Re: Is Honda EU7000iS overkill for me? Inverter technology capped at 7000?

I'm having 2nd thoughts about springing for the Honda eu7000is at $4k. My use is probably considered light-duty use at probably 2-3 times per year with mostly 1 day outages. Worst case scenarios are major ice storms and hurricanes with 5+ days of no power but that doesn't happen every year.

I can get the Yamaha EF6300 for $3060 from pplmotorhomes.com (a lot of these RV sites have good prices), and that includes shipping. That's $500 less than electricgenerators.com for the same Yamaha machine and almost $1k less than the Honda. Just that for 700 extra watts of starting power?

Is the maintenance really that bad on the Yamaha? I've heard needing a funnel to change the oil and special Yamaha spark plug tool.

Someone said the Honda eu7000is provides many more minutes of surge power but I can't find a clear answer on that. I know I can buy a lower watt unit but since I'm a mechanics/engineer/gadget guy like Tim Allen on Home Improvement, I just can't help it Should I just use up more of my savings and spring for the Honda?

The Honda 7000 has fuel injection that some have had nagging hard to diagnose problems with. For a purley standby unit do you really need/want the advantages of fuel injection? If you used it on a food truck 8-10 hours a day the fuel savings might be an advantage.
I think the 6500 has a carburetor.
My experience is with my 6000 Kubota powered unit is 3000 watts is a realistic load unless you have electric heat or water heater.

Honda has two 3000 inverter units. The difference is weight, surge/running watts, noise level and electric start.

I thought long and hard about the Yamaha EF6300 before I bought the Honda. The Yamaha has a smaller engine,less surge watts. Its harder to move around with the 4 fixed wheels. To change the oil you have to unscrew the side of the machine. Also there is no backup pull start if the battery is dead. I think the Honda EU7000 has a better resale value. Used ones on E-bay usually don't last long. The parallel option makes a used one attractive to owners who want more power.

I really like my MEP-002a, which I got on the 'bay for less than $500 + $120 shipping. The 002a is rated at 5kw by the military, but is really good for ~7kw of continuous load. Mine will run my entire house, including the 3 ton AC unit if you do a little sensible load management. I had to put a hard start kit on the AC in order to keep from tripping the breaker on startup, but the now the genny grunts a bit and away the AC goes...

It is an onan set, so built like the proverbial brick outhouse. Its' only drawback is that its somewhat noisy - it's an air cooled diesel - but if you can live with that, it is a great set. My generator resides in an outside shed, and is ~15 feet from my bedroom and I have no problems with the noise inside the house.

Fuel economy is also great. We recently had a power outage for about 23 hours and the generator only used 7 gallons of offroad diesel - gotta love that! It's rated at 0.5 gallon/hour at full load...

Another plus for a diesel set is that the fuel doesn't go bad as quickly as gas...

Yeah, I researched that and the Honda eu7000is is way easier to service than the Yamaha. Although, I've decided to just buy an oil extraction pump kit off Amazon to change the oil now - so easy and no loosening the drain bolt, no drain pain and no crush washer to replace.

And again, I've now set my eyes on the Honda again. Guess I should just bite the bullet and buy this expensive machine. I'm just having a hard time justifying the cost for something that will be used on a rarity.

The other inverter generator that has 5000+ watts is the Briggs and Stratton Q6500, but heard the sine wave has a lot of distortion and that it doesn't handle surges very well - something the Honda does extremely well.

I don't think you'll be disappointed. You right . The Honda GX390 does take surges very well. Honda's been building that motor and using it in a lot of different machines for a longtime. If you can hang on a few more weeks Honda usually has a sale around late November on them. I bought when that had the sale from Electric Generators direct and paid by check and got a larger discount.

I just went through hurricane Michael with a eu7000. I was 16 days without power. I put 384hrs on it, only turning it off to change the oil. I didn't even turn it off to gas it up. It will run 18 hrs on 5 gallons of gas. It is two times quieter than my eu2000. I ran a 5000 window air conditioner, microwave,coffee maker, 2 fridges, 1 freezer, 220 submersible pump, and all the lights I wanted. I would turn the well off to turn the water heater on for hot showers then turn the well back on. Its worth the extra money. I tried running 2 eu2000's parallel for 1 fridge and 1 freezer and my 5000 air con and it would keep tripping so I ended up just using the 7000 for everything. I tried to see how many watts the 7000 would take and it finally tripped at 9200 watts. You get what you pay for.
