Very quiet and easy to move.

I just bought this and so far am pleased. It started up easily, is easy to move around and very quiet compared to other generators I've owned. I like the dual fuel feature as well. The quick start set up guide had some incorrect information which was frustrating so I recommend using the full instructions book instead.

User friendly generator for RVing

I bought this particular model because of its low decibal rating, portability, previous reviews and its dual fuel capability. The set up is straight forward and the instructions easy to follow. I look forward to using this on our cross country adventure this summer!!

Easy Assembly, started right up

I havent put it underload just yet, but the assembly was easy and it started easily. In reading the manual I did opt not to use the supplied oil, as our low temps can easily be below 20 degrees Fahrenheit. I opted for this model because it is an enclosed inverter generator, while it is true we have whole house surge protection, the idea of having <3% THD is attractive to protect the many electronic boards in some of the strangest places in the house :)

Great generator.

We bought the igen11000Dfc in the beginning of March 2025. It was so nice to be able to have a gen on and be outside and be able to have a Conversation and not have to yell. Is was super easy to set up put together and start. Gen comes with good Quality tools to put the gen together.

iGen11000DFc

Received the item and it was very well packaged. Unit is solid, compact and easy to assemble. The front panel is well organized and easy to read. I was happy to find a generator option that output sufficient power at a low THD. Will be using propane as a fuel source but glad to have the gas option in case I need it.

Easy to set up and works great

I only have about one hour on it. Set up was relatively easy. Even though they provide an excellent screw in funnel, adding oil was a little messy. (definitely stuff a rag under while adding oil.) My only minor complaint is that it seems a bit louder than other "quiet" inverter type generators that my friends have. Other than that, I am very happy so far.

First Operating Review

I wrote my unpacking review a month ago, and now I've completed my first break-in operation. After checking the oil - just to make sure - and connecting the battery and filling the tank with gas that was treated with Sta-Bil, I rolled it out into the driveway. I decided to try using the remote fob, and it started right up. It ran a little rough at first, but I realized I had it in Eco mode, so I switched that off and it smoothed right out. I let it run for 30 minutes, and plan to do that every month until I get through the 5 hour break-in, then change the oil. I was very impressed by how smooth it ran and how quiet it was. After I shut it down, I plugged in the battery tender that came with it to make sure the battery stays in good shape. I am still very happy with my purchase.

SSOOOO QUIET

It was easy to assemble. I am running the break in period now and am hopeful everything will run smoothly. I'm transitioning from a gas unit that is VERY heavy and VERY loud so this is wonderful. My husband couldn't even hear it through the phone. So far, I'd recommend this generator!

Great Inverter

Just purchased the iGen11000DFc to use as whole home generator. Haven't gotten a chance to use. Everything about it seems to be straight forward EXCEPT for how to turn off the gas.. I'm going to assume you would turn the fuel switch to propane but there is nothing in the Manuel to indicate this. I guess I will just have to run it and switch to propane (with no tank attached) to see what happens. If someone reads this that knows the answer please respond.

Everything I could ask for!

I purchased this generator to backfeed my panel during the next power outage. I selected this generator because it has the perfect requirements for just such needs; plenty of power, safe to use with sensitive electronics, dual fuel, 50a output, easy to store and move around, and it all comes at a fair price.
