About 18kW Generators
18kW generators from PES Supply provide reliable standby power from top brands including Generac, Cummins, and Briggs & Stratton. A 18kW standby generator powers most mid-size homes (1,500-2,500 sq ft) with central air conditioning and standard appliance loads. These air-cooled standby generators run on natural gas or propane and start automatically during power outages when paired with an automatic transfer switch (ATS).
A 18kW generator can power your central AC, refrigerator, well pump, lights, and major appliances during extended outages. Most models include Mobile Link Wi-Fi monitoring for remote status checks and maintenance alerts. PES Global Group offers competitive pricing, fast shipping from our Louisville, KY operations, expert technical support from our product team, and bulk pallet ordering for contractors and EPCs.
Use our Generator Sizing Calculator to verify {kw_num}kW meets your electrical load requirements, or contact our team for installation guidance and transfer switch compatibility.
