Generac RD05034 50kW Protector Series Diesel Generator
The Generac RD05034 is a high-capacity 50kW diesel standby generator, part of the rugged and code-compliant Protector™ Series. Designed for large residential estates and demanding commercial settings, this model delivers clean, reliable power with intelligent digital controls, impressive fuel efficiency, and a durable steel enclosure built to withstand tough environments. It offers both single-phase and three-phase output options, making it adaptable for a wide range of applications.
Powered by an inline 4-cylinder liquid-cooled diesel engine, the RD05034 operates at a consistent 1800 RPM, reducing wear and extending service life while ensuring smooth and steady power delivery. This model is capable of producing 200 amps at 120/240V single-phase and up to 173 amps at 120/208V three-phase, making it a reliable choice for facilities with high electrical demands.
The generator is equipped with Generac’s Evolution™ Controller, a user-friendly digital interface that includes a multilingual, two-line LCD display with color-coded backlit buttons. Real-time diagnostics, maintenance reminders, and operating status are easily accessible. The system also supports Mobile Link™ connectivity (sold separately), which allows remote monitoring and control from any smart device.
With Quiet-Test™ mode, the RD05034 runs weekly self-tests at a lower RPM, reducing both sound and fuel usage. It operates at just 65 dB(A) during test cycles and 70 dB(A) under full load, quiet enough for many residential settings. Sound performance is further enhanced by its sound-attenuated steel enclosure, coated in a sleek gray finish for durability and weather resistance.
The generator includes a UL 142-listed, double-walled base fuel tank, simplifying installation and meeting local code requirements. At full load, it consumes approximately 4.3 gallons of diesel per hour, while half-load operation requires just 2.3 gallons per hour, offering up to extended runtimes depending on tank size.
With UL 2200 listing, EPA emissions certification, and a 5-year limited warranty, the RD05034 is built to deliver reliable, compliant, and long-lasting backup power when it’s needed most.

Power is Convenience
I bought this for my business as backup power. I also have an apartment above it which is rented out. We experienced a power outage and thanks to this 50 kW Generac generator, my business was able to stay open and operate like nothing had happened. The rental had power as well. This generator has proven to be a great investment.
