The Generac 7043 can power most single-family homes, including HVAC systems, refrigerators, freezers, sump and well pumps, lighting circuits, home offices, and essential electronics. With 22 kW (LP) and 19.5 kW (NG) output, it comfortably supports whole-home coverage for typical 2,000–4,000 sq ft households.

Why Homeowners Choose the Generac 7043

The Generac 7043 is one of the most popular residential standby generators because it delivers powerful, quiet, and dependable whole-home backup with minimal maintenance. Its 22 kW output provides enough capacity to run HVAC systems, refrigeration, lighting, and critical appliances at the same time — ensuring continuous comfort and safety during an outage.

This model’s G-Force™ industrial-grade engine is designed for long-life operation with pressure lubrication and faster response under load.

    Posted by Brian K. on Sep 19, 2017

    Generac&#039;s 7043 22kW is a great generator. I am writing this review a year after installation. I live in Fort Meyers Florida and had installed in August of 2016. No power outages until Irma. Worked perfectly and ran almost 5 straight days before power was restored. I could not be happier with this purchase.
