20 Kilowatt Standby Generators

Standby home generators capable of producing a constant 20 kilowatts of electrical power are among the most popular generators available for home use. Installed in combination with the correct automatic transfer switch, they can supply enough power for homes that use two central air conditioners and still keep other essential appliances running.

Central air conditioners are one of the highest loads found in most homes and their motors draw three to six times more current during startup than when they are running. A generator must be able to supply the startup current for a brief moment and the running current continuously. Norwall Power Systems offers 20kW standby generators from four companies. They bundle generators in a variety of packages to meet the needs of most homes and keep their critical and essential appliances running during a power outage.

Generac Guardian Series generators use their overhead valve industrial v-twin engine which was designed specifically for use in a generator. The 36 horsepower, 999cc engine runs on LP gas to produce 20kW of power, or on natural gas to produce 18kW of power. The choice of two fuels and conversion in the field makes this generator a versatile machine suitable in most locations as a backup for utility power. The generator’s functions are handled automatically by the Evolution Controller in conjunction with the automatic transfer switch. This 20kW generator will easily start and run a 5 ton central air conditioning unit along with other appliances.

Cummins Onan standby generators offer the comfort and security of a home generator built by a company well known for reliable and powerful engines. The 993cc v-twin overhead valve engine used in 18/20kW generators was designed by Cummins Onan and runs on either LP or natural gas. Unlike many other standby home generators, this unit turns loads on and off as needed in order to supply power where it is needed, when it is needed, without overloading the generator. The generators are shipped set up for natural gas and are converted in the field for LP gas installations. In addition to other loads, the Cummins Onan 18/20kW generators supply enough power for air conditioners and other critical loads.
