What our Experts Think

• Commercial‑class 80 kW standby power
  The Kohler 80 kW 120/240 V Standby Generator (KG80R‑QS) delivers robust 120/240 V single‑phase backup, ideal for very large homes, light commercial spaces, small business electrical systems, and critical loads that require dependable emergency power when utility service fails.
• Industrial‑grade liquid‑cooled engine
  Equipped with a Kohler 6.2 L liquid‑cooled engine running at 1800 RPM, this unit ensures cooler and quieter operation, fuel efficiency, and long‑term durability compared with air‑cooled counterparts.
• Clean and stable electrical output
  Advanced alternator design with tight voltage/frequency regulation and ultra‑low total harmonic distortion delivers clean power, protecting sensitive electronics, servers, and smart systems under heavy load conditions.
• Fast automatic standby response
  The Fast‑Response® X excitation system brings the generator up to full rated load within ~10 seconds of a utility outage, minimizing disruption to critical circuits.
• APM402 controller with diagnostics
  Provides advanced controller functions, local display data, diagnostics, and optional remote communication interfaces, simplifying monitoring and maintenance.
• Rugged steel enclosure with acoustic control
  Sound‑attenuating steel housing with corrosion‑resistant finish and internal silencers keeps noise around ≈68 dB @ 7 m, making it feasible for outdoor placement near occupied areas.
• Dual‑fuel flexibility (NG/LP)
  Operates on natural gas or liquid propane (LP) with simple field conversion—allowing installation flexibility and continuity during extended outages.
• Pre‑installed block heater
  Improves cold‑weather starting and warm‑up times, enhancing reliability in climates with lower temperatures.

Q&A

Q: What power output does this 80 kW generator provide?
A: It delivers 80 kW (80,000 W) of continuous standby power at 120/240 V single‑phase, perfect for very large homes or light commercial backup systems.

Q: What fuel does it use?
A: It runs on clean‑burning natural gas or liquid propane (LP) with simple field conversion while maintaining emission certification.

Q: What type of engine and performance features are included?
A: It’s powered by an industrial‑grade Kohler 6.2 L liquid‑cooled engine with hydraulic valve lifters, and has advanced power regulation for clean, stable output with ultra‑low harmonic distortion.

Q: How quickly does it respond to power outages?
A: When paired with an automatic transfer switch (sold separately), it accepts full load and restores power in about 10 seconds.

Q: How durable and weather‑ready is the enclosure?
A: The sound‑attenuating steel enclosure has a corrosion‑resistant powder‑baked finish and internal silencer, keeping noise under ~68 dB at 7 m and ensuring long‑lasting performance.

Q: What control and monitoring features are included?
A: It comes with a Kohler APM402 controller for system monitoring, diagnostics, and remote communication via PC/network interfaces (remote monitoring sold separately).

Q: Is a block heater included?
A: Yes — a pre‑installed block heater supports easier starting and quicker warm‑ups in cooler conditions.

Maintenance Tips

• Regular Oil & Filter Changes: Change engine oil and filters every 100–200 hours or annually to protect the industrial V‑8 liquid‑cooled engine and extend service life.
• Coolant System Checks: Maintain proper coolant level and flush periodically to prevent overheating and ensure efficient cooling under load.
• Controller & Diagnostics Monitoring: Use the APM402 controller to review system diagnostics, check fault logs, and plan preventive maintenance.
• Air Filter & Ignition Checks: Inspect and replace air filters and spark plugs regularly to ensure efficient combustion, reliable starting, and fuel economy.
• Weekly Exercise Runs: Run automatic or manual exercise cycles weekly to keep internal components lubricated and avoid moisture buildup in the engine.
• Load Testing: Periodically test under actual load to confirm stable 120/240 V output and frequency regulation for sensitive devices.
• Fuel System Maintenance (NG/LP): Check fuel lines and pressure for clean, consistent delivery to prevent performance issues.
• Battery & Electrical Connections: Verify battery charge, clean terminals, and tighten connections for reliable automatic starts and controller communication.
• Enclosure & Ventilation Care: Keep the steel sound‑attenuating enclosure clean and free of debris to promote airflow and prevent corrosion.
