Generac Protector Diesel Series 15 kW Standby Generator

All the conveniences of modern living - heat, central air, refrigeration, communication - are nothing without power. When the power supply is disrupted, our lives and businesses can come to a sudden halt. An automatic standby generator protects you from power failures, restoring power within seconds of an outage, so you can have peace of mind and the power you need.

Generac’s new Protector® Series diesel generators raise the bar for residential and light commercial diesel generators. Building and zoning codes can vary wildly from one region to another. In the past, the only answer was to order expensive, custom-configured solutions. Until now.

Generac’s diesel-powered Protector Series features Code Ready, a set of popular preconfigured options and a range of code-driven accessories, so you can feel confident that your generator will be able to conform to the required local codes. The Protector Series is versatile, adaptable, meets UL requirements, and is an affordable optional standby diesel generator for your backup power needs.

Evolution™ Controller
The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons.

Quiet-Test™ mode
All standby generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Protector Series standby generator runs its self-test at a lower, quieter RPM than standard operation.

Mobile Link™ Connectivity
Mobile Link™ Connectivity allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet or PC. Easily access information, such as the current operating status and the generator’s maintenance schedule. Connect your account to an authorized service dealer for fast, friendly and convenient assistance. With Mobile Link, your generator is taken care of before the next outage.
Mobile Link comes standard with Protector Series 22 - 100 kW gaseous models and diesel (RD) models.  The Wi-Fi device is standard on every Protector series generator except for the RG13090/RG15090 and the 130 - 150 kW gaseous models.

5 Year Limited Warranty
We are proud of our innovative product design, high quality and first-class reliability so we stand behind them with a strong 5-year limited warranty.

Code Ready
The Protector Series offers compatibility with a variety of environments, with external vent and fill, a UL/CUL 142-listed, double-walled base tank, a UL/CUL 2200-listed generator, and a wide range of code-driven accessories.

Additional Features

  • NEW! Extended tank option. Full load runtime of 2+ days!
  • Ease of installation and service: External viewing window for easy inspection of generator status and breaker position. Removable doors for easy service and fuel fill access.

Rated 4 out of 5 by from Ready for Hurricanes! We have been wanting a whole house generator for years. Purchased the generator in September of 2021. Did not receive it till June of 2022. Once the generator was installed, we ran the 24 hour breakin process. The generator is quieter than I thought it would be. Easy to fill with diesel and it looks good. So far we are extremely satisfied with our purchase. No fear now when a hurricane hits the Gulf Coast.

Rated 5 out of 5 by from RD03022 built well We chose this model because of the Perkins Diesel engine. Easy to perform maintenance, has long service intervals. Two minor complaints, it should come standard with coolant heater installed from factory, and should come with longer warranty for the price paid.

Rated 3 out of 5 by from 48 kw generator You did not drain the radiator froze up, had to heat rad to remove your fluid, and put in glycol for my regions cold weather. the oil must come out and filled with oil for this climate, it was most likely mineral oil, has to come out. Otherwise Gen OK. do not like the fact it will not turn over unless coded.. I worked on generators in the mega watts for te last 60 years, so I know what I am doing! I wanted a 100 kw gen. but not available in single phase.

Rated 3 out of 5 by from 30 Amp cord too short I find the provided 10' 30 amp cord too short since GENERAC recommends on their web site using at least 20 ft cord. Safe Extension Cord Use When you’re using your extension cord, make sure it is long enough to keep the open frame generator at least 20 feet away from your home. For emergency power, make sure it’s long enough to keep your generator away from windows and doors so that carbon monoxide does not enter your home.

Rated 4 out of 5 by from Quiet and powerful Just had our old generator swapped out for this one. Glad the case is rust-proof. Also more silent when running

Rated 5 out of 5 by from Off to a good start... Having suffered through a multi-year problem with a competitor's product issues, I went searching for a reliable alternative. I was very professionally guided in my search by TSE Power Solutions and chose a 48KVW diesel unit from Generac. The planning and execution of the installation were exceptionally well handled and went as scheduled. Start-up proceeded flawlessly as well and we are now set to go. I am confident this will be a much better, long term solution that will fit our needs.

Rated 5 out of 5 by from No effort peace of mind Installed this during a rebuilt with doing so kept in mind during planning. No other service disconnect needed in my area and re-located my electrical system around it. Not had the chance to have it function as it should, but looking forward to not having to lift a finger for it to do so! Have the same at my Mom's home on a 16KW and most of the time she doesn't know power has switched over.
