Olympian Generators

Olympian is Caterpillar Inc.'s value-tier generator brand — purpose-built to deliver reliable standby power at a price point 20-30% below full Caterpillar industrial units. The brand exists because not every commercial building needs a Cat 3500-series engine and EMCP 4.5 controls; many need a proven diesel generator that starts on demand, runs when called upon, and costs less to purchase and maintain. Olympian fills that gap by pairing Perkins engines — manufactured by Caterpillar's own subsidiary, acquired in 1998 — with straightforward packaging and controls, all backed by the global CAT dealer network.

Every Olympian generator uses a Perkins engine, from the compact 400 series (2.2L, 4-cylinder) powering the smallest 15-22 kW models up through the 2000 series (12.5L+) in 500 kW units. The GEP-series naming convention identifies the engine source: GEP = Generator, Electric, Perkins. Gas-fueled models use the GEH prefix. Older models follow a D-series naming convention (D75, D100, D125, D200) that is still commonly found in the installed base. The Perkins engine platform is one of the most widely deployed diesel engine families in the world, with parts and service available in over 180 countries. That global footprint makes Olympian a common specification in developing markets and remote locations where local parts sourcing is critical.

The practical advantage of Olympian is access to the CAT dealer network without the CAT price tag. The same technicians who service Cat industrial generators maintain Olympian units, and Perkins parts are available globally with short lead times. The trade-off is clear: Olympian generators do not carry the resale premium of full CAT units, and the simplified control panels lack the deep integration and remote monitoring capabilities of Cat's EMCP platform. For buyers who plan to own a generator for its full lifecycle rather than resell — and whose loads do not require the sub-3% THD power quality of a Kohler or the cold-weather extremes of a Cummins — Olympian is often the smarter financial choice in the commercial standby segment.
