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 :)

Preparing for the 2025 hurricane season in Florida. I have 4 other generators that are smaller and one large PTO generator that attaches to my tractor to run the farm operation when the hurricanes blow through. I wanted something for the whole house so I wouldn't have to deal with all the cords and moving things around to keep all the refrigerators going. I also wanted an inverter that provides clean power as the other generators have not been so kind to sensitive electronic equipment. So I installed an interlock on my house panel and bought this Westinghouse inverter and so far I'm very impressed. The build quality looks great and they supplied all the tools to put the wheels, supports and handle. Ten minutes and done. Later this week Ill break it in and give it a test run on the house panel.

This Westinghouse iGen4000DFc dual fuel generator offers so much flexibility during a power outage. Running a generator can really make a difference in a difficult situation. Having backup power brings real peace of mind, especially during Southern California Power Outages. It's a great investment for any homeowner.

We boondock a lot during our travels, and need a dependable generator/inverter for power. Tried solar, just too much trouble, and the cost is ridiculous. I've owned 6 generators over twenty plus years and Westinghouse has been the best so far. Lite weight, easy to store using propane exclusively.

Can not believe how quiet and how easy this inverter was to set up. It took me longer to triple check the directions to make sure I wasn't missing anything. Added oil, checked level, paired the remote. Boom fired up. Can't wait to use this with our travel trailer this year!

Premier essai, tourné mais ne part pas avec gazoline , après quelques essaye je vérifie la bougie ( elle est sec et j'ai du feu ). Change pour le propane, il part je remets à la gazoline sans arrêter le génératrice et elle continue à fonctionner. Depuis cette essai elle fonctionne à la gazoline. Maintenant le remote fonctionne et fonctionne pas même avec une nouvelle batterie????. Après quelques essai avec le propane le régulateur fait défaut ( le gaz ne passe plus) . J'ai passé des heures (des jours) pour comprendre les défaillances et faire des essais. J'ai toujours pas essayer le ats (automatic transfer switch) je crois pas que je vais pouvoir faire confiance à cette génératrice comme backup (system solar) pour ma maison, c'est la première génératrice qui me donne autant de problèmes

I purchased this generator after a two day power outage. I look at other manufacture but Westinghouse had the best review and was still in my price range. I order it on Apr 6 and hit arrive 11 April. I decided to not let in run with not load for a few hours and did a oil change. The generator is super quiet i had it on my back deck and could barely hear it in my living room. I know this is the first day having this generator but so far i am glad i purchased this brand.

I purchased this inverter/ generator as part of a bus conversion into a tiny home to supplement my solar system during inclement weather. It has exceeded my expectations, quiet, reliable, and the remote function is a fantastic feature. It's also less expensive than similar models, most of which do not have a dual fuel capability.

Just puchesed for home emergency use (I live in Florida). Powers my whole house with the exception of the high draw appliances (stove, oven, Hot water heater) at the same time. If I want to use the high draw items I simple turn off other circuits to use them, then switch back after usage is complete.

This generator exceeded my expectations with its impressive power capacity and remarkably low noise level. It easily powers my entire home, including major appliances, without any issues, making it a reliable backup during outages. Unlike other generators I've used, this one runs much quieter, which is a huge plus, especially for extended use. The efficient performance and smooth operation make it a fantastic investment for anyone looking for a powerful yet quiet generator. Highly recommended!
