How many watts do I need for the generator to power my whole house during an outage?

It depends on your appliances (fridge, AC, lighting, etc.). Generally, a model between 10,000–13,000 watts covers most of an average home's essential needs. We can help you calculate exactly how much you need based on your specific appliances.

Does it only run on gasoline, or are there other options (like propane)?

We have Dual Fuel models that run on both gasoline and propane, so you can choose whichever fuel is available. We also offer Tri-Fuel models that add natural gas — great flexibility, especially if gasoline runs out when you need it most.

What's the warranty, and how much maintenance does it need?

Warranty typically ranges from 1 to 3 years depending on the model, covering the engine and core components. Maintenance is simple: regular oil changes, filter cleaning, and spark plug checks every few months.

Since I installed it, we haven't lost power once during storms. It fit perfectly with our home setup and it's incredibly easy to start and maintain. I recommend it completely. It's a really practical investment for anyone who wants peace of mind when the power goes out.

What I loved most was the design. It looks modern and sleek, and it blends in perfectly with the setup at home. It doesn't feel like a cheap, bulky unit — it's compact and fits right into the space. On top of being practical, it really improves the overall look of the backup power setup. Very satisfied with this purchase.

Receptacles are protected by circuit breakers to protect cords and prevent overloading. The 50-amp, 120/240 volt receptacle is protected by a toggle-type circuit breaker. All other AC receptacles have push-button type breakers. The 12-Volt DC charging outlet is currently limited to 10 amperes. 30-Amp and 50-Amp receptacles require the correct generator cables for use (sold separately). A portable generator needs to be ready for use at all times.

Generac added maintenance reminders right on the hour meter, and the convenient fuel gauge provides at-a-glance fuel monitoring. Many portable models have controls located in inconvenient locations, making it difficult to access them quickly, especially in the dark. We gave control placement careful consideration, with comprehensive control sets conveniently located for easy access.

Not for sale in California.

Most open-box units are returns that have never been used. A small percentage were minimally used and refurbished.
