Generac RG08045 Protector Series 80kW Generator Features:
Generac RG08045 Protector QS Series 80kW Generator
The Generac RG08045 from the Protector QS Series is a heavy-duty 80kW single-phase standby generator, built for those who need maximum power output and seamless automatic backup. Ideal for large estates, commercial operations, or mission-critical applications, this model offers quiet operation, intelligent controls, and rugged reliability, all within a compact and weatherproof enclosure.
At its core, the RG08045 features a 4.5L turbocharged inline 4-cylinder engine, engineered to run at a low 1800 RPM for reduced wear and longer service life. The turbocharging and aftercooling provide enhanced performance and higher output without sacrificing fuel efficiency. Operating on either natural gas or liquid propane, this generator delivers consistent power under the most demanding conditions.
This model produces 80,000 watts of clean, utility-grade single-phase power at 120/240V, regulated with ±1% digital voltage precision and less than 5% total harmonic distortion (THD). This makes it safe for microprocessor-based appliances, HVAC systems, and sensitive electronics. The integrated Evolution™ Controller provides real-time monitoring, automatic shutdown alerts, and maintenance logs—all accessible via the onboard screen or remotely through Mobile Link™ Wi-Fi.
Despite its high capacity, the RG08045 is impressively quiet, operating at just 68 dB(A) in exercise mode thanks to its sound-attenuated aluminum enclosure and internally mounted critical-grade muffler. The enclosure is RhinoCoat™ powder-coated, wind-rated to 145 mph, and designed for installation just 18 inches from a building (where local codes allow), offering versatility without compromising performance.
Fuel consumption is optimized for both power and efficiency. At full load, the unit uses approximately 10.8 gallons/hour of propane or 1,063 cubic feet/hour of natural gas. Standard features like the smart battery charger, closed coolant recovery system, and UV/ozone-resistant hoses enhance durability and ease of maintenance over the generator's lifetime.
Fully UL 2200 listed, EPA emissions certified, and approved for installation in California and Massachusetts, the RG08045 meets the highest industry standards for safety and environmental compliance.
