Overview#

The Olympian GEP110 is a 110 kW diesel generator powered by the Perkins 1104C-44TAG2 — a 4.4-liter inline-4 engine representing the top of the Perkins 1100 Series four-cylinder range for generator applications. Delivering three-phase 277/480V power at 60 Hz, the GEP110 serves the upper end of the mid-range commercial standby market: larger office buildings, multi-story retail, hospitality properties, and light industrial facilities.

The 1104C variant of the Perkins 4.4-liter platform features enhanced fuel injection and turbocharging calibration compared to the 1104A used in the smaller GEP65 and GEP88, extracting maximum output from the four-cylinder architecture before the step up to the six-cylinder 1106 engine in the GEP150. This makes the GEP110 the most power-dense four-cylinder option in the Olympian GEP lineup.

At 110 kW, the GEP110 occupies a competitive class alongside the Cummins C100D6, Kohler 100REOZJF, and Generac SD100. The Olympian's value-tier pricing combined with Caterpillar dealer service access makes it attractive for commercial building operators who need 100+ kW backup power without the premium cost of a Cat C-Series unit. The four-cylinder engine also offers a smaller footprint than six-cylinder alternatives in this power class, which can be advantageous on space-constrained commercial sites.

Frequently Asked Questions

Is the GEP110 the most powerful four-cylinder Olympian generator?
Yes. The GEP110 uses the Perkins 1104C-44TAG2, the highest-output variant of the 4.4-liter four-cylinder platform in the Olympian GEP lineup. For more than 110 kW, the step up is to the six-cylinder Perkins 1106 engine in the GEP150.
How does the GEP110 compare to the Cummins C100D6?
The GEP110 delivers 110 kW from a compact four-cylinder Perkins engine with Cat dealer service. The Cummins C100D6 offers 100 kW from the QSB platform with Cummins dealer support. The GEP110 provides slightly more power and Olympian value-tier pricing, while the Cummins benefits from broader QSB fleet commonality.
