Generac RD01525 15kW Protector Series Diesel Generator Features:

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.

Generac RD01525 Features:

  • 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.
  • 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:
    • 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
    • Isochronous Governor – electronic governor control for tight and precise load response and voltage (+/- 1%) and frequency regulation
    • Available in single- and three-phase configurations

    It is about time Generac finally came out with a diesel model of generator. I wish it could have been air-cooled instead of liquid cooled though. I live out in the middle of nowhere and diesel is a lot easier to get than propane. Not sure what equipment I will get to unload this. We can cross that bridge when we get there. All I know is I bought this gen and I hope it will do everything I need it to do. Based off my own calculations I need about 14kw so this 15 kw gen should be plenty of power. Can't wait!
