Generac RG03015 30kW 1-Phase Generator
The Generac RG03015 is a 30kW Protector® Series standby generator engineered for premium residential and light commercial backup power applications. Designed to run on natural gas or liquid propane, it features a powerful liquid-cooled engine, intelligent controls, and a compact, corrosion-resistant aluminum enclosure, delivering peace of mind with every outage.
At its core, the RG03015 is powered by a Generac 1.5L inline 4-cylinder engine running at 3600 RPM. This naturally aspirated engine is built for long-term use and dependable performance, featuring a hydraulic lifter system and gear-driven oil pump for minimal maintenance. The system incorporates True Power™ Technology, producing clean, stable power with less than 5% total harmonic distortion—safe for sensitive electronics and high-end appliances.
The generator utilizes an electronic isochronous governor, achieving ±0.25% frequency regulation and ±1% voltage regulation, even under variable load conditions. It’s equipped with the Evolution™ Controller, which includes a two-line multilingual LCD and comes standard with Mobile Link™ remote monitoring, so users can track operating status and maintenance alerts from anywhere via smartphone or computer.
The RG03015’s sound-attenuated aluminum enclosure is powder-coated for durability and corrosion resistance, and it features an integrated muffler and sealed design for quiet operation—rated at just 73 dB(A) under full load and 59 dB(A) during exercise mode. Its compact footprint supports installation as close as 18 inches from a structure when local codes allow.
Fuel efficiency is another strength, consuming approximately 5.4 gallons per hour of propane or 492 ft³/hr of natural gas at full load. Smart features like the closed coolant recovery system, 2-amp smart battery charger, and sealed ball bearings contribute to extended lifespan and reduced service requirements.
This generator is UL 2200 listed, compliant with EPA emissions standards, and eligible for sale in CA and MA, reflecting Generac’s commitment to both safety and environmental responsibility.
