How Inverter Technology Works

Inverter generators utilize a different type of alternator than standard generators to generate AC power. The raw power produced is converted from DC to AC power by a computer controlled inverter module. The engine speed varies depending on the electrical demand, which significantly reduces noise and fuel consumption compared to a standard portable. The end result is a portable generator with reduced weight and size and power that is ultra-clean, capable of safely powering sensitive electronics.

Lightweight and Compact

The iX Series is up to 40% lighter than a standard generator of equal watts. And the built-in handle makes it easy to move with minimal effort.

FlexPower™ Operation Modes

Use high mode for large loads or battery charging, or eco mode to save fuel and reduce sound levels even more.

Follow up - August 23rd, 2010:

Generac finally replaced my leaking unit. Hours of work on my part. The new unit idles quite different. On normal mode it idles significantly lower and flucuates up and down. In the economy mode, it simply idles even lower. The first unit seemed to idle normal (who knows) or high. In economy mode it flucuated up and down as stated in the manual. The electrical outlets are different. The first unit had commercial 120v outlets - one plug vertical, one horizontal. I spent $50 for a commercial extension cord. The new unit has regular (parallel) plugs. Therefore I'll need to buy an adaptor. Unbelievable. If there are any more problems I simply will pay someone who knows what they are doing (Generac's service people do not) or throw the unit out. Stay away from this unit. And stay away from Generac.

June, 2010 - Unit was defective out of box. Significant oil leak from engine even when not running. Took to 2 authorized Generac service shops. Still leaks. Leak is where 2 aluminum machine surfaces come together. Still trying to get resolution. Generac customer service fair at best. Takes considerable time to reach a human being. The unit already looks 2 years old due to the handling by the repair people and I've never used it. Generac has still not offered to replace. They "don't make the motors". A great excuse. I will contact Amazon corporate office if necessary to tell them not to sell this company's products and file in small claims court if necessary against Generac. Please consider other manufacturers' if you are looking for a small generator. I may be contacted at nfre at comcast dot net for photos of leak. Thank you.

Got this unit for a very low price through Amazon.com. Cranked it up and worked ok. Next day it would not hold voltage. took to authorized dealer. 4 weeks later told me the carborator was dirty and not covered by warranty. male bovineshit! the nit needed adjusting. a warranty charge. but why wait for the manufacture to come up with the payment when you can hit the owner with a $75 "clean carburetor" charge. What a rip off.

I bought this generator to use for charging a battery bank on an RV. I never got it to run for even 10 minutes, when I took it to the factory authorized repair depot they said it had water in the gas, they told Me this before working on it? The tank I fill My equipment with is used on 7 engines none of which had problems. The so called repair I had to pay for and accomplisehed nothing, I still cannot use the generator, and the factory refuses to warranty it. I have two other generators a 6 kw and a 1 kw both constant speed type one of which cost 99 dollars and puts this one to shame. Very poor showing and no warranty beware.

Purchased it as on open box item from Amazon.
Lesson learnt - If you wanted it by a certain date, tell Amazon to NOT use UPS. Their supply chain sucks.
They cannot intercept a parcel and hold at their office for pickup on the same day of supposed delivery.
It will only be available the next day. So beware. Have them ship by Fedex instead. Fedex can even
contact their truck drivers by radio on delivery day.

I puchased the generator to go camping and to power a laptop and a fan at 90F weather.
The generator ran for 15 minutes and died. The load was most likely less than 400W, just charging the
laptop and running a small box fan. The generator was supposed to supply 800W continuous.

It turns out the inverter board is bad. A known problem with this product line. I later saw reviews of the
1600W model not able to keep up more than 800W.

STAY AWAY FROM THIS GENERAC PRODUCT LINE.

However, Amazon is great to make good my loss, but is not without headaches.

I bought the generator to use on my boat to occasounally keep the batteries up when camped away from the marina. I was very disappointed in the loud noise level. It is advertised and also marked on the box as "ultra quiet"; well it is as loud as a lawn mower under load, and I wouldn't want to listen to that noise for hours at a time, nor subject that to fellow boaters nearby. I had expected maybe something that wouldn't be a nuissance and may be nearly as quiet as a Honda. No way, this is unacceptable to have to listen to.

Poor repair service. In the 7 months the repair company has had the thing it hasn't been touched. Generac won't approve the repair of a generator that didn't work right out of the box. Worst customer service i have ever seen. DO NOT BUY!!!

The price, $285, was good. IT'S NOT as good as the small Yamaha I had but it is definitely worth the price.
It's a little noisy and not well-wired. If you look at the jumble of wires inside the case you'll see a lot of chintzy consumer electronics connectors made for very light indoor duty. The engine and inverter look well-made.
The ECO throttle is not steady, it wavers up and down with a steady load and it does not even come into play outside a narrow load range in the middle of the generators power, about 100 watts either side of mid-range 400 watts.
It starts easily. The oil level shutoff switch was coming on too early, even when the oil level was fine. It also came on whenever the genset was tilted at all. The factory said there's no adjustment so I disconnected the switch. I plan on using this genset on a Personal UltraLight Dirigible and I can't have it shutting off just because it's not perfectly level flight.
I put a tachometer/time log on it which rings every five hours and warns me to check the oil. This would've been a good original equipment item.
The mufflers not much good and I want to add a pipe to the output to quieten the high frequency noise coming from the exhaust valve clattering as it closes and opens.

I wanted to build my test airship as Cheeply! as possible or I would've used the Yammy or the Honda. This is about a third their price so I'm not surprized it ain't great. But it works fairly well.
