Continuous monitoring and real-time status alerts through the Kohler Energy Management App help you track performance and health remotely, adding convenience and peace of mind.
-
Strong motor-starting capability (PowerBoost)
PowerBoost technology assists with starting heavy loads such as air conditioners and large motors without significant voltage sag, keeping other circuits stable.
-
Clean, stable power with DVR protection
DVR technology guards sensitive electronics against harmonic distortion and unsteady power—important for control systems and modern devices.
-
Durable, service-friendly aluminum enclosure
Corrosion-resistant housing with removable panels allows easier maintenance access and long-term outdoor durability.
-
Easy installation & flexibility
Sturdy aluminum base can be mounted on gravel or concrete pads, and the generator works with Kohler transfer switches and load management accessories.

Maintenance Tips
-
Run Weekly Exercise Cycle
Allow automatic self-test (~20–30 min) to keep engine lubricated and ensure quick start readiness.
-
Follow Oil & Filter Service Schedule
Change engine oil, oil filter, and air filter at recommended intervals to protect engine life and efficiency.
-
Inspect Battery & Charger Monthly
Check voltage, terminals, and corrosion for reliable automatic startup during outages.
-
Monitor Fuel System (NG/LP)
Verify fuel pressure, regulators, and connections for stable 3-phase performance under load.
-
Clean Air Intake & Enclosure
Keep vents clear of dust and debris to prevent overheating and airflow restriction.
-
Test Under Load Periodically
Simulate real demand to confirm voltage stability and balanced 3-phase output.
-
Use App Connect Monitoring
Track alerts, runtime data, and system health remotely for proactive maintenance.
-
Inspect Electrical Connections
Tighten breakers, terminals, and transfer switch wiring for safe operation.
-
Check Engine Components
Inspect spark plugs, hoses, and belts for wear and replace as needed.
-
Schedule Annual Professional Service
Ensures warranty compliance and long-term reliability.
