The Wildcat FR0015D4 is built around a heavy-duty KOEL R550 Series 4-cycle industrial diesel engine, operating at a steady 1800 RPM for long-term reliability and consistent output.

Engineered for a wide range of applications—including residential backup, off-grid systems, oil & gas, telecom, emergency response, and remote installations—this unit is designed to perform in demanding environments without compromise.

• Wildcat FR0015D4 15kW diesel generator is powered by a robust KOEL 4-Cycle, R550 Series Industrial Powertrain engine with a maximum 1800 RPM.
• This diesel generator is designed for residential, off-grid, oil & gas, telecom, disaster relief, military, first responder, remote locations, and more.
• Wildcat FR00015D4 has exceptional motor-starting capacity making it ideal for all types of climates. Premium-grade materials are used in its construction for durability.

High motor-starting capability allows the generator to handle large loads and variable conditions across different climates. The alternator features a double-delta configuration for efficient power delivery, paired with a high-performance R120 Automatic Voltage Regulator to maintain stable voltage under changing loads.

With total harmonic distortion kept below 3.5%, the FR0015D4 delivers clean, stable power suitable for sensitive electronics and modern equipment.

A digital control system provides real-time monitoring of voltage, current, frequency, engine speed, oil pressure, and coolant temperature through a backlit LCD interface. The control panel also supports diagnostic tracking, fault code display, and programmable weekly exercise cycles for streamlined operation and maintenance.

The sound-attenuated enclosure reduces operating noise to approximately 78 dBA, while removable panels allow for straightforward servicing and inspection.

Safety is built in with a 63-amp circuit breaker, protecting both the generator and connected equipment. This liquid-cooled, single-phase unit is configured for 120/240V output and is designed for outdoor installation.

Manufactured to meet recognized standards including IEC 60034, NEMA MG 1.32-33, ISO 8528-3, CSA C22.2 No.100-14, and UL 1446, the FR0015D4 is built to commercial-grade specifications.

Features 

• The alternator is fast and efficient with its double delta connection. While the R120 Automatic Voltage Regulator is well known for its high performance. AVR regulates voltage variations to deliver a constant, reliable power supply.
• The 15kW Wildcat generator is safe for modern electronics that have microcircuits. Total harmonic distortion is less than <3.5% which makes it perfect for use at home, work, or the farmhouse.
• The digital controls monitor the generator’s voltage, current, power, frequency, engine speed, oil pressure, and coolant temperature on a back-lit LCD for ease of use.
• The user-friendly control panel for troubleshooting has a scrolling display. It monitors diagnostic conditions, displays system fault codes, and sets weekly exercise cycles.
• Wildcat FR0015D4 15kW 60 Hz generator has a sound attenuated enclosure which allows it to run quietly at 78 dbA. It has removable panels to allow for easy access for repairs and maintenance.
• This Frontier Series liquid-cooled generator is equipped with a 63 amps circuit breaker that keeps the generator and you safe.
• The commercial-grade diesel generator is offered in a single-phase configuration. The 120/240v transportable model can be installed outdoors only. It is shipped free of cost and comes with free lifetime technical support.
• Wildcat FR0015D4 15kW 60 Hz generator is manufactured according to the following standards: IEC 60034, NEMA MG 1.32-33, ISO 8528-3, CSA C22.2 n°100-14 and UL 1446.
• It is backed by a 3-year, 5,000-hour limited warranty for on-grid and off-grid applications. 

Wildcat FR0015D4 15kW diesel generator has been redesigned for higher performance and longer life. This Frontier Series generator is the industry's most powerful liquid-cooled generator in its class. It protects your family, house, store, farm, and office when grid power fails. In the event of hurricanes, tornadoes, storms, and wildfires power may go out for several days. At such times this diesel generator will run for days and weeks so you can have the comfort and convenience of electric power when you need it the most. This 60HZ single-phase generator produces ample electricity to power essentials at home and work. Run the air conditioner, coffee maker, oven, freezer, refrigerator, and computers, and continue with the day as usual.   

Wildcat's generator can be used at the ranch house to power household electronics or at the construction site to complete work projects on time. This backup generator has a large fuel tank and a liquid-cooled engine so you can run it for weeks with complete peace of mind. It guarantees maximum power, torque, and consistency under all working conditions. The premium power quality protects all costly electronics. The weather-resistant enclosure makes it a perfect choice for seaside environments and extreme climates. 

Wildcat FR0015D4 15kW diesel generator offers convenience, safety, and security to both home and business owners. If you are looking for fuel economy, dependability, and durability in a standby generator, look no more! The commercial-grade engine, full-pressure oil lubrication system, long run time, fuel economy, automatic voltage regulator, digital controller, and affordable price make it the perfect choice. It is hand-assembled in the heartland of America, Wichita, KS.
