Default Generator vs Inverter Generator

I am looking into investing in a generator to use in the event of a natural disaster/quake/STHF. To use around the house to run like the fridge, some lamps, charge phones. So I am looking for something that isn't loud and blows smoke when running.....

I have been looking at:

https://www.amazon.com/dp/B0041K09D8...ing=UTF8&psc=1

And have been looking at the Harbor Fright ones as well.


Where I am not completely understanding is the generator vs invertor generator.

Any generator I have ever used in my life is, pour gas in the tank, put the choke on, pull the cable till it starts and plug in what you wanna use...

Help me understand Invertor Generators vs a generator....

A standard generator makes AC power.

An "inverter Generator" produces AC power, converts it to DC, then back to AC. This is done to "clean" the power... Less of a chance of having your lights dim and brighten, and less chance of causing damage to sensitive electronics.

I read through that before posting... Am I understanding that (?)... Basically they are both the same, But the inverter generators produce a safer power, stabilizing the power output...(?).

Yes... The inverter acts as a buffer for any power spikes or other fluctuations in power delivery. The difference is especially noticeable if you are drawing close to the generator's limit... The one you are looking at is a good one... With the Inverter type, it is easy to run them together to up the output. A feature I really like....

10.4.


And that's what pulled me into this one, was they can be run in parallel with another one.

Like the guys already said. A generator runs at 3600rpm to provide 120v at 60hz. It essentially regulates voltage and hrz by always running at the same rpm. This provides acceptable power for a refrigerator or other device not sensitive to power changes. Inverter generator can vary the rpm to conserve fuel and provides clean power equal to what you are getting from the power company. Good for computers and other sensitive devices

costco has inverters on sale every now and then, light, portable, quiet, and efficient so you are not advertising to the entire neighborhood that you have one. they also have costco's warranty as long as you save the box and everything.

i owned a harbor freight but it was loud and because it is a 2 stroke i had to mix in 1/50 parts oil which makes it give off a stronger odor.

This I think is one of the biggest advantages of inverter generators, is their ability to cut back on RPM under light loads. Very good for fuel both fuel efficiency and noise.
Regular 3600 constant RPM generators are often hideously inefficient and noisy as hell.

Power quality of an inverter generator is usually but not always better than a regular generator. For a regular generator, the good power quality is a function of the design of the rotor and stator and cheap generators to to skimp on build quality there.

A buddy has a pair of those Champion generators. The inverter broke and he sent it in for repair under warranty. Other than that he likes them. One data point for what it's worth.

That Yamaha paper is some information, some clever marketing. While it's true that inverting generators produce cleaner waveforms and can vary their RPMs (which does help with fuel consumption), a lot of the other 'benefits' are simply mfg design decisions.

I have that 2kw Yamaha. I've put decent hours on it now and think it is a solid unit that handles loads well.

I also have a cheap $90 Harbor Freight 2-stroke 700w. Bought it more as an experiment and backup unit to loan out. The power is very dirty. The wave form is ugly, with frequency drifting a bit and generally runs on the lower side of voltage. Dipping and hanging below 100V even on light loads was common. I used a line conditioner that brought the voltage back up but doesn't help a lot with cleaning up the waveform. For most people and uses, the dirty power will probably be ok, but it really depends.

I've also used many other types/sizes of generators. Generally speaking, for most people I'd suggest spending the extra dollars and getting an inverting type generator. If you have the cash, Yamaha and Honda make the best in the small portable class.

I just have generators. Two on gas, one runs on propane. All make noise. Just have them outside on garage side of house, away from living area. One is in RV, so we can just go out to the RV for easiest access to power. One is in my concession trailer, so would just have to hook up to house, but with four 100lb propane tanks, I could run for a week on it!

Just make sure your do the calculations for the size you really need. Decide what you want to run, add up the requirements and then buy a little extra. Then, make sure you have a nice system for connecting to the house and disconnecting the utility company. A nice setup is not cheap.

I really enjoy my Honda EU 2000 Inverter Generators. I use 2 of them to run my a/c on my travel trailer and only 1 just to run the normal lights and water pump. they are so fuel efficient because they pretty much idle when a low load is on them and they are super quiet. I will absolutely recommend them.

just my .02

I bought a Honda 2000 as well, 3/4 gallon lasted me 3 nights for about 4 hours each night running a projector for the kids to watch movies and lights while we where out camping

If campground camping is even a slight possibility go the inverter route. I had the pleasure of camping next to a family that insisted on running their non-inverter genset most of the day last weekend. Fortunately the weather was great and we spent most of the time away from out campsite but that thing was obnoxious.

Dont get me wrong. I have a similarly loud generator for home use but my nearest neighbors are over 1/4 mile away.

I went with yamaha because of the price, fuel economy and output. My choice was the ef2400ishc. Thing is a workhorse and sips fuel under low load. Will run 90% of the 13.5k rv ac's and the rest of the rv load(no microwave and ac at the same time) . 40hrs and one oil change, filter cleaned and sprayed out carb. Very quiet too. Perfect when the power is out; ran 30cf fridge, 14cf freezer and tons of lights for two days on 3 gallons of fuel.

I have the Harbor Freight Predator 4000 and have used it twice. It ran two 20 cu ft stand up freezers and a refrigerator. For interior electronics I got a Goal Zero Yeti 1500 and portable solar panel. The Goal Zero is pure sine wave AC, and I have not tested it on a computer.

The Harbor Freight model is cheap, works well, and durable. It sat in the sub and rain for two years before I put in oil and fuel to run it. Loudness was around 65 db if I recall. I need to make a sound proofing enclosure for it. The Honda units run with less nose, at a price. The Goal Zero units make no noise, no exhaust, and can be recharged with the sun, at a cost.

I got the Honda eu2000i a few yrs back, they were going for 899$ or so.

I also have a off grid solar system. 2x 135 watt panels, had a PWM charge controller, now got a MPPT, and 4 104 amp hour batteries and a 1k watt inverter.
enough to run small electronics charge batteries etc. Its about time for me to get new batteries though as these seem to not hold a charge like they use to.

I plan on getting a 2k watt inverter later on as needed.

I bought this North Star with a Honda engine. I've had it for a couple years, starts on the first pull. It's enough to power my house via a panel with selective circuits.

I tried the sound box with my old one and the heat was just too much. I gave up and bought quiet ones.

My BIL has the Honda Eu-2000. He bought it for their camping trailer. A year ago we were camping on the beach at South Carlsbad. I believe the camp regulations call for all generators to be shut down by 9:00pm. One night we went to bed around 11:30. He got up and had to go out to turn the genny off. It was so quiet that it was not heard over the sound of the surf.

inverter is the way to go will be cheaper in the long run with fuel consumption,quieter and clean power for items with circut boards.

After couple power outages presently in our area, yesterday I got Honda eu2000i. Already started break in process. Very quite, on my backyard (townhouse) with closed doors, I place generator 2 feet away and I do not hear it.
To chose right model, my main concern was neighbors-I didn't want to make them really angry (beside fact I will have electricity and they won't) over exaust sound. Honda serves the purpose. Also Honda is known to be one of the most dependable trusted. Little bit price, but you get what you pay for.

I have had a Honda eu1000 for many years of trailet camping.
A superior unit.
I have a Champion of about 3200 watts for home backup
A good basic unit
Just acquired a Champion 7000/9000 watt dual fuel to use at th we ranch where I have a 500 gallon propane tank..it should run cleanly forever on propane. It will be hooked up eventually to a transfer switch. It will run my pumps, appliances, but no ac

I'm setting up a second alternator on my ZJ to use as a on board welder and of course a second power source.
I picked up a Leece Neville big rig alternator that I'm gonna use along with a dual battery setup and a inverter.
I figure the vehicle setup takes priority as I can plug the house into it in a pinch, set idle at 1500rpm and be good to go, at home and out in the wilderness.
After that, looking to augment the vehicle setup with solar panel system.

Lastly, always on the lookout for a good deal on a stand alone gen set for home/camp use.
Just see the on board vehicle setup as the priority as it'll handle all faucets of power gen needs.

I have the Champion 2k and I'm sorry to report after only 5hrs run time (hardly use it) I notice slow fuel drip from the shut off dripping onto the electronic. Thank God I notice at home instead of the camp ground. Can you image after running about 3-4 straight out there....BOOM. I'm hoping its still under warranty or not expensive, I really like it.
