26kW Generators

26kW generators from PES Supply provide reliable standby power from top brands including Generac, Cummins, and Briggs & Stratton. A 26kW standby generator delivers full whole-home backup for large residences (3,500+ sq ft), estates, and small commercial buildings with heavy electrical 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 26kW generator can power your multiple HVAC zones, electric range, well pump, pool equipment, and full home circuits 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.
