Generac RG02515 25kW 1-Phase Generator
The Generac RG02515 is a liquid-cooled, 25kW Protector® Series standby generator built for residential and light commercial use. Designed to run on either natural gas or liquid propane, this generator offers robust performance in a compact aluminum enclosure, making it a great fit for those who require reliable, quiet, and long-term backup power. Its True Power™ Technology ensures clean energy delivery, making it safe for sensitive electronics and high-powered equipment alike.
Under the hood, this model is powered by a 1.5-liter Generac in-line 4-cylinder engine, operating at 3600 RPM. The engine is naturally aspirated, featuring a hydraulic lifter system and gear-driven oil pump, ensuring low-maintenance operation and long service life. With an electronic isochronous governor, the RG02515 maintains ±0.25% frequency regulation and ±1% voltage regulation, delivering stable power even as loads fluctuate.
This generator includes Generac’s Evolution™ Controller, featuring a multilingual LCD screen that provides real-time status updates, maintenance alerts, and system diagnostics. The system also comes Wi-Fi enabled via Mobile Link®, allowing you to monitor the generator remotely using a smartphone, tablet, or computer.
Designed for quiet operation, the sound-attenuated aluminum enclosure reduces operational noise to 72 dB(A) at full load and just 59 dB(A) during exercise mode. The internal critical-grade muffler is mounted within the enclosure, minimizing installation complexity and maximizing safety. Its compact footprint and ability to be installed within 18 inches of a building make it ideal for properties with space constraints (when compliant with local codes).
In terms of fuel performance, the RG02515 consumes approximately 4.7 gallons of propane or 430 ft³ of natural gas per hour at full load, with highly efficient burn ratios across lower load levels. The system also features a closed coolant recovery system, smart battery charger, and sealed ball bearings to promote longevity.
This model meets UL 2200 listing and is compliant with EPA emissions standards, including CA/MA requirements.
