Generac

Generac — The Name Behind America's Backup Power

Founded in 1959 in Waukesha, Wisconsin, Generac invented the affordable home standby generator and has dominated the residential backup power market ever since. Today, Generac holds the largest share of the home generator market in North America — a position earned through decades of engineering reliability, product innovation, and a product range that covers everything from lightweight portable inverter units for camping and RV use through to whole-house standby systems that kick on automatically within seconds of a power outage. If the lights go out, Generac is what most prepared homeowners have waiting in the garage or bolted to the side of their house.

Home Standby Generators — Automatic Whole-House Protection

The Guardian series standby generators represent Generac's most complete home protection solution. These permanently installed units connect directly to your home's natural gas or liquid propane supply and monitor grid power continuously. When an outage is detected — day or night, whether you're home or away — the generator starts automatically and transfers power to your home within seconds. No extension cords, no manual starting, no fuel cans. The lights stay on, the refrigerator keeps running, the sump pump keeps working, and the furnace or AC continues operating as if nothing happened.

The range on this page covers the 10kW Guardian with 100 Amp transfer switch — suitable for essential circuits in most homes — up to the 26kW Guardian with 200 Amp transfer switch for true whole-house coverage including HVAC, appliances, and everything else on the panel. Both are WiFi-enabled via Generac's Mobile Link system, allowing remote monitoring of generator status, run hours, and maintenance alerts from a smartphone.

Portable Generators — Flexible Power Anywhere

Generac's portable lineup covers a wide output range for different use cases:

• 2,500W Inverter Generator — compact and quiet, produces clean stable power safe for laptops, phones, and sensitive electronics. Ideal for camping, tailgating, and light home backup.
• 3,300W Inverter Generator — steps up the output with USB charging ports, still in a lightweight package suited to RV use and outdoor power needs.
• 10,000W Portable Generator — electric start, heavy-duty frame, suitable for serious home backup covering multiple large appliances, or demanding jobsite use.
• 12,500W Tri-Fuel Portable Generator — the standout in the portable range. Runs on gasoline, propane, or natural gas, giving genuine fuel flexibility for emergency situations where one supply may not be available. Electric start, quiet operation, and long runtime make this a serious emergency preparedness investment.

Transfer Switches & Power Management

A generator is only as useful as the transfer system connecting it to your home. Generac's 200 Amp Automatic Transfer Switch is service entrance rated and NEMA 3R outdoor rated — meaning it can be installed as the main service entrance panel, simplifying the installation considerably. The 7000 50 Amp Load Manager adds intelligent load prioritisation, ensuring critical circuits are powered first when generator capacity is limited, using wire-free technology for cleaner installation.

Accessories & Protection

Rounding out the ecosystem, Generac offers purpose-built accessories that extend system reliability. The Surge Protective Device (SPD) guards connected equipment against voltage spikes — essential when power is restored after an outage. The Oil Heater Kit for 9kW–22kW air-cooled standby units ensures reliable cold-weather starting by keeping engine oil at optimal viscosity. The LTE Propane Tank Fuel Level Monitor integrates with the Mobile Link app to provide real-time tank level readings, preventing the one scenario every generator owner dreads — running out of fuel mid-outage.

Pressure Washers

Generac also brings the same engineering rigour to outdoor cleaning with their gas-powered pressure washers. The 3,000 PSI / 2.4 GPM residential pressure washer tackles driveways, decks, siding, and vehicles with serious cleaning power, featuring quick-change nozzle tips for different applications and an ergonomic spray gun designed for extended use without fatigue.
