Generators

Portlandia Electric Supply is a generator supplier for homeowners, contractors, and facilities buyers alike. This collection covers the two ways people buy backup power: permanently installed standby generators that start automatically during an outage, and portable generators you wheel out when you need them. Standby units here run from 10kW air-cooled home models up through 150kW liquid-cooled commercial systems, with natural gas, propane, and diesel fuel options in single-phase and three-phase configurations.

Our generator sales desk works with the brands that own this category. Generac Guardian and Protector series cover residential through light commercial; the Kohler 26RCA delivers 26kW of whole-home power with Kohler's commercial-grade engine; Briggs & Stratton Fortress units scale to 150kW with 120/240V output and 700A breakers for serious facilities. Every standby generator ships freight with liftgate options, and most pair with an automatic transfer switch from our transfer switch collection for a code-compliant installation.

Not sure what size you need? Send us your panel schedule, square footage, or the list of circuits you want backed up — we size generators daily and will match the unit, fuel setup, and transfer switch in one quote. For job sites, events, and emergency backup on a budget, our portable Generac models start under 2kW and run up to 9,400W with electric start and CO-sense shutdown.
