Generac GP3000i Inverter Generator: More Power Than Most Inverters

Note: I get commissions for purchases made through links in this post.

The Generac GP3000i inverter generator is much like its smaller cousins – the iQ2000, the iX2000, and the GP2200i – except that it’s…well…bigger and more powerful. That’s where the “3000” comes in.

Let’s take a quick look at what’s different with the GP3000i from Generac so you’ll be able to tell why you should get one before your next outing.

Generac Likes Its Trademarks

“PowerRush”, “True Power”, “PowerDial” – Each of these is a trademarked term for a feature of this Generac inverter machine.

“PowerRush”, they say, “delivers over 50% more starting capacity allowing you to do more with less”.

What does that really mean? 50% more than what?

On the Generac website, there’s an asterisk at the end of that phrase but no footnote to explain it. You have to dig a little further to find the reference on the downloadable brochure.

There it says, “Increases electrical current upon demand; above rated output when starting electric motors”.

That’s still not extremely helpful or clear. I think it means that you can get 50% more than the “normal” starting wattage, but don’t quote me on that. I also can’t tell you how to increase the current “upon demand”. Sorry.

Don’t get the idea from this that “PowerRush” is a bad thing. It’s good. It’s just not clear how it all works.

“TruePower” is a little more straightforward. It’s simply Generac’s term for providing clean power especially for your handheld devices like phones and tablets. There are 2 USB ports for that purpose.

The “PowerDial” is a nifty feature. It gives you choke, run, and off settings all in one place; that is, on one dial. It’s normal to only need one of these settings at a time, so putting them all together makes sense.

Other features include an Economy Mode that adjusts the speed of the engine to automatically save fuel and run more quietly when you don’t need its full power capacity.

Being a larger inverter generator, this is not exactly a lightweight unit. It weighs 60 pounds, but if you’re strong enough, you can tote it around using the built-in handle. After all, this is supposed to be a portable generator.

The GP3000i generator is parallel ready, but you probably won’t need a second one. If you need that much more power, you might be better off getting a larger model from the start.

Generac includes oil (10W-30 or SAE 30 is recommended), an oil funnel, an appropriate tool kit, and the owner’s manual with your purchase.

Finally, on the control panel, you’ll see several status lights. You get a low oil warning light, an overload light, and a ready to use LED. They’re there to protect your investment from damage. Note that the machine will automatically shut down if there is too little oil left inside the 0.6L tank.

Conclusions about the Generac GP3000i

I haven’t said much – nothing actually – about the noise level of this machine. Being an inverter, it is quieter than most, almost by definition. Generac doesn’t provide decibel levels for their generators, claiming that there’s no standard (even though there is a de facto standard that virtually all other manufacturers use).

It should be among the quietest of the 3000W generators you can get. It will be louder than a 2000W but softer than a standard, non-inverter model.

Overall quality should be just as good as any generators that come from Generac. Some may argue that that isn’t saying much, but Generac does have a good reputation for its machines.

And hundreds of current owners agree that this is a wise purchase. Share in their wisdom by getting one for yourself today.
