Generac Generators and Outdoor Power Equipment

Robert Kern founded Generac Power Systems in 1959 to produce portable generators for Craftsman and later entered the RV generator market. In 1989, they revolutionized the home generator market by producing the first practical and cost effective automatic generators for homes use and for small to medium-sized businesses. 

The Generac Guardian Series is the world’s leading home standby generator. Generac surpassed one million units in February 2013. When making a purchase decision, 7 out of 10 homeowners choose Generac Guardian for their home backup generator.

Generac Generator Features and Benefits

In 2009, Generac standby generators received the Good Housekeeping Seal of Approval. 
Five years later, Frost & Sullivan—a recognized leader in the information and growth consulting industry—presented Generac with the 2014 Natural Gas Generator Company of the Year award for their continuous efforts to identify industry needs and bring new natural gas products to the market in residential, industrial, commercial, mobile and general generator applications. 

Generac was the first manufacturer to utilize an engine designed specifically for the performance requirements of a generator. The Generac backup generator for home uses an Overhead Valve Industrial (OHVI) engine with features like a plateau-honed cast-iron cylinder walls which promote heat dissipation for longer engine life. The plasma-filled moly rings reduce oil consumption and engine wear. A fully pressurized lubrication system keeps critical bearings and other parts immersed in oil at all angles of operation. Low oil shutdown prevents engine damage, and the dual element air filter extends service intervals while protecting the engine from dirt. 

Generac Automatic Transfer Switches (ATS) are designed with state of the art features to ease standby generator installation and operation. They manage power for entire homes or a few essential circuits. Their manual transfer switches safely connect a home's electrical system to a Generac portable generator. 

Generac PWRcell Clean Energy Whole Home Power

From the company that invented the home backup generator and manufactures the leading home generator brand comes the Generac PWRcell Solar + Battery Storage Whole Home Power system. Generac PWRcell fulfills the promise of Solar Power with electricity from the sun for home or business.

Generac PWRcell is a fully managed system that operates efficiently during an outage to keep a home or business functioning with power for critical and essential circuits. The PWRcell inverter can charge a PWRcell Solar Battery from the grid or from solar panels. It supplies power to the main circuit breaker panel instead of a subpanel, making electricity available to the entire home instead of a few selected circuits.

During an outage or utility blackout, the PWRcell Automatic Transfer Switch islands the system from the grid and keeps supplying power from the solar panels until the sun goes down. Competing systems begin drawing on battery power immediately. When the sun no longer reaches the panels, the solar battery is already partially discharged. The system keeps the PWRcell Solar Battery Bank charged until darkness, then uses the battery to power your home or business through the night.

PWRcell easily scales from 9kWh to 18kWh of energy storage with additional battery modules and to 36kWh with a second battery cabinet.
