Generac Next Generation 10000 Watt 10kW Dual Fuel 50 State Air Cooled Home Standby Generator 7257

 

Generac 7257 10kW Generator Features:

The Generac 7257 10 kW Standby Generator is a compact yet powerful solution for safeguarding your home’s most essential systems during a power outage. With its robust design and innovative technology, this generator ensures reliable performance that automatically activates when utility power fails. Designed for both propane and natural gas operation, it gives homeowners the flexibility to choose the fuel source that best fits their environment and budget.

Engineered with Generac’s G-Force engine, the 7257 is built specifically to withstand extended run times and high-demand conditions. Unlike modified off-the-shelf engines, this purpose-built design delivers durability and reduced maintenance requirements. Coupled with True Power™ electrical technology, the generator provides clean, stable power with less than 5% total harmonic distortion—ideal for sensitive electronics, appliances, and HVAC systems.

Ease of use and monitoring are at the forefront with Generac’s Evolution™ controller. The two-line multilingual LCD display (English, Spanish, French, Portuguese) offers system status, maintenance intervals, and intuitive controls. Built-in Wi-Fi connectivity allows you to monitor your generator from anywhere using a smartphone or computer. Additionally, its Quiet-Test™ self-diagnostic mode runs at a lower RPM, saving fuel and operating more quietly while ensuring your generator is always prepared.

Practical installation and peace of mind round out the package. The sound-attenuated aluminum enclosure features a corrosion-resistant finish for long life and can be installed as close as 18 inches from your home (subject to code requirements). Backed by a 5-year limited warranty and certifications through trusted third-party testing, the Generac 7257 offers homeowners a complete backup solution they can trust when it matters most.
