Generac Protector Series 30,000 Watt (30kW) (120 / 240V) 3-Phase Liquid Cooled Dual Fuel Standby Generator

The Generac RG03015 is a premium 30kW 3-phase standby generator from the Protector® Series, purpose-built to deliver dependable backup power for larger homes, commercial buildings, and light industrial environments. With the capability to run on either natural gas or liquid propane, this generator delivers quiet, clean, and reliable energy using advanced features like True Power™ Technology and Mobile Link™ remote monitoring.

At the heart of this generator is a Generac 1.5L inline 4-cylinder engine, running at 3600 RPM to supply continuous-duty power with low maintenance requirements. This engine’s natural aspiration, combined with its electronic isochronous governor, ensures ±0.25% frequency regulation and ±1% voltage regulation, which translates into stable output that protects your sensitive electronics and commercial-grade equipment.

The generator provides 120/208V three-phase output, offering the kind of balanced, high-capacity power distribution needed for multi-load applications in businesses and larger residences. With True Power™ Technology, total harmonic distortion stays below 5%, ensuring that even the most sensitive electronics remain protected from damaging surges or fluctuations.

Noise-conscious environments will appreciate the sound-attenuated aluminum enclosure, which includes a fully enclosed muffler and durable RhinoCoat™ powder coating. The RG03015 operates at 73 dB(A) under full load and 59 dB(A) during Quiet-Test™ self-check mode, ensuring low disturbance in both residential and commercial settings.

This model comes standard with Generac’s Evolution™ Controller, a smart interface that provides real-time system status, maintenance reminders, and fault alerts. Integrated Mobile Link™ connectivity allows you to monitor and manage your generator remotely from a mobile device or computer—ideal for facility managers and tech-savvy homeowners alike.

Fuel performance is efficient, with the generator consuming approximately 221 ft³/hr of natural gas or 2.1 gallons/hr of LP at full load. It also includes features like a pressurized lubrication system, sealed ball bearings, and closed coolant recovery system, all designed to extend the life of the unit and minimize service requirements.
