Hands-Free Automatic Operation
When the power goes out, this generator eliminates the trouble of dealing with a fuse box in a dark basement or going outside in a storm to start a portable generator. After all LP or natural gas and electrical connections are completed, the Generac 5875 is ready to run 24/7 and requires absolutely no manual operation, no fueling, and no extension cords. The generator responds within seconds of power outages, so inconveniences like heat or air conditioning loss and burst pipes or spoiled food are quickly avoided.

Initial setup is easy. The generator arrives pre-wired and equipped with the necessary installation gear: a 200 Amp service entrance rated transfer switch , an outdoor connection box, a flexible fuel line pigtail, and a composite mounting pad. (Additional items and tools may be needed to complete the installation to meet local codes. Consult a licensed professional for further details.)

The unit can be programmed to perform a weekly exercise at the time of your choice, so it will be ready for continuous and reliable operation on a moment's notice. For convenience, it also offers clear, digital controls, an at-a-glance status indicator, and an external GFCI outlet to accomodate your outdoor power needs.

Superior Technology for Secure Output, Quiet Operation, and Durability
Thanks to Generac's exclusive True Power Technology, this generator provides clean, continuous power, so sensitive electronics and microchip appliances like laptops and HVAC equipment can be operated without the worry that unexpected power surges bring. Also featuring Generac's patented Quiet-Test technology, this generator is truly neighborhood-friendly: it's self-test mode is as hushed as an idling car to ensure that your daily routine is unaffected.

The generator's aluminum enclosure offers superior corrosion resistance and is protected by Generac's proprietary RhinoCoat system--a unique process that binds the paint to the metal surface for a long-lasting, durable finish. This allows the generator to sit outdoors and withstand harsh weather conditions without developing an unsightly appearance.

Like all Generac generators, this model is UL (Underwriters Laboratories) listed for safety.

Rugged, Worry-Free Design
The generator features the 999cc Generac OHVI® Engine, an exclusive air-cooled generator engine with a high-performance design that can accommodate large electrical loads. The engine optimizes power to respond swiftly to changing conditions. To add to your peace of mind, the engine requires routine maintenance only once every two years, or after 200 hours of use.

This Generac generator meets CARB requirements. It requires a Group 26R 12-volt minimum 525 CCA battery (sold separately).
