Generac 7042 – 22kW Guardian Generator with Wi-Fi (Scratch & Dent)
The Generac 7042 22kW Guardian Series Standby Generator provides dependable, whole-home backup power with the latest Guardian-series technology — now offered as a Scratch & Dent model for exceptional savings. Delivering 22,000 watts on LP and 19,500 watts on natural gas, this generator is sized perfectly for homes needing reliable protection for HVAC systems, well pumps, appliances, sump pumps, freezers, electronics, and more during any outage.
Powered by the Generac G-Force 1000 Series engine, the 7042 is engineered for long-duration, high-demand performance. Its plateau-honed cylinder walls, plasma-moly piston rings, and Spiny-Lok cast-iron sleeves are designed to withstand continuous operation in extreme conditions. With True Power™ Technology, it delivers clean, stable electricity with <5% THD, ideal for sensitive electronics, variable-speed HVAC systems, and modern appliances. Solid-state, frequency-compensated voltage regulation holds power within ±1%, giving the 7042 excellent motor-starting capability for heavy loads.
The 7042 includes standard Wi-Fi connectivity, enabling complete remote monitoring through Generac’s Mobile Link® app. Users can check generator status, maintenance intervals, run and exercise history, and battery condition from any smartphone or computer — providing real peace of mind whether at home or away. The quiet, sound-attenuated aluminum enclosure is rust-resistant, weather-tested, and capable of withstanding winds up to 150 mph. Generac also certifies this model for installation as close as 18 inches from a structure, offering flexibility for tight lots and side-yard installs.
A Scratch & Dent version of the 7042 gives homeowners the chance to own one of Generac’s most popular standby generators at a drastically reduced cost — without sacrificing factory performance, reliability, or warranty coverage.
