Our Generac generator is what saved our belongings and is what ultimately saved us as a family. There was utter chaos and destruction outside, but my home was air conditioned and I had power.

We searched all over Indiana for the right company. Horizon was by far the most professional, and their installation was flawless. Our generator runs like a dream!”

The Generation 8 10 kW standby generator is a compact, dependable solution for homeowners who want automatic protection for critical loads, refrigerators, sump pumps, lighting, and a few circuits.

The 10 kW’s robust G-Force engine and optimized excitation design provide high motor-starting capability and efficiency, while an enclosed, weather-resistant cabinet reduces noise and simplifies installation close to the home.

The unit starts automatically when utility power is lost and returns to standby when power is restored, so families can focus on what matters during storms and outages.

Its weather-resistant enclosure and sound-attenuated design mean the generator installs neatly near your home with minimal visual and acoustic impact. The Evolution™ controller provides a two-line multilingual LCD for clear status and logging; Mobile Link® remote monitoring is available to keep you informed from anywhere.
Horizon installs each unit as a turnkey solution, including site assessment, permit handling, concrete pad/mounting, transfer switch wiring, and final commissioning, and registers the factory 5-year limited warranty for you. For homeowners who want reliable essential-circuit protection without the footprint of larger systems, the Generation 8 – 10 kW is a smart, low-maintenance choice.

Frequently Asked
Questions (FAQs)

If you more questions to know you can check more query related to Generac®

Is the 10 kW model good for whole-house backup?

The 10 kW is best for essential-circuit protection (fridge, sump pump, lights). For whole-house coverage, we usually recommend 14 kW or 18 kW, depending on your HVAC and load; we perform a free load assessment to confirm.
At normal load, the unit measures about 61 dB(A) at 23 ft; in Quiet-Test exercise mode, the noise falls to ~57 dB(A). Proper siting further reduces perceived noise.
The unit runs on natural gas or propane (LP). Fuel line sizing and fuel pressure must meet generator requirements; Horizon evaluates this during the site visit.
