Kohler 150ERESC 150kW Generator Features:
Kohler 150ERESC 150kW Generator
The Kohler 150ERESC is a high-performance 150kW standby generator designed to deliver dependable three-phase or single-phase backup power for commercial buildings, critical infrastructure, and large-scale operations. Featuring a powerful 8.8L V8 turbocharged engine, this model is built to provide uninterrupted, utility-grade power with smart control capabilities, durable construction, and exceptional voltage response.
At its core is a PSI 8.8L V8 industrial engine, turbocharged and charge-cooled, designed for high-output applications while maintaining 1800 RPM operation for smoother performance and longer lifespan. The engine is EPA-certified for stationary emergency use and can operate on natural gas, liquid propane, or dual-fuel configurations, offering excellent fuel flexibility. Fuel consumption is rated at 1965 cfh NG and 713 cfh LP at full load.
This model uses a brushless, rare-earth permanent magnet alternator, managed by Kohler’s Fast-Response® X excitation system, which allows ±0.5% voltage regulation and <4% total harmonic distortion (THD). The system can handle 100% of rated load in one step and offers peak motor-starting capacities up to 570 kVA at 480V, making it ideal for large HVAC systems, pumps, and data centers.
The APM402 controller provides intelligent system monitoring and diagnostics. Featuring a digital display, Modbus® compatibility, and real-time status updates, it supports NFPA 110 Level 1 applications when configured with required accessories. It also includes integrated thermal overload protection, programmable alarms, and advanced communications options.
The sound-attenuated enclosure is available in steel (standard) or aluminum (optional), both designed to protect against harsh environmental conditions. The aluminum model is wind-rated up to 150 mph. Sound levels remain controlled at 73 dB(A) under full load, thanks to vertical airflow, internal silencing, and UL-rated acoustic insulation.
With a full load, this generator's cooling system processes over 25.5 liters (5.6 gallons) of coolant and includes features like a centrifugal water pump, critical silencer, and optional block heaters for cold climates. Maintenance is simplified with features like an oil drain extension, vibration isolation, and remote emergency stop.
The unit is UL 2200 listed, CSA certified, EPA compliant, and approved for use in California and Massachusetts, making it one of the most adaptable and regulation-ready units in its class.
