The Generac 7042 is an air-cooled whole-house standby generator rated at 22 kW peak and 16 kW continuous on natural gas. It starts automatically during an outage and runs until utility power returns, paired with a 200 Amp automatic transfer switch. True Power technology keeps total harmonic distortion under 5 percent, so sensitive electronics run cleanly. It suits homeowners who want full-house backup without a liquid-cooled unit's cost and upkeep, though it is louder and less powerful than those bigger models.
