1500kW Generator Rental (1875kVA)

Prime Power Rentals 1500kW generator rental (1875kVA) provides reliable power to meet the most demanding requirements. They are designed and built to withstand tough environments at construction sites and provide dependable temporary power at entertainment venues, construction sites, and disaster recovery operations. And to safeguard the environment, the 1500kW generator features an integrated 24-hour fuel tank with a fluid containment system.  

The 1500kW / 1875kVA diesel generator offers a prime rating of 1360kW (three-phase) and a standby rating of 1500kW (three-phase).  277/480V output voltage.  An electronic governor maintains frequency to ± 0.25% from no load to full load. It features an auto start-stop that allows the generator to start from a remote location. The unit features a powder-coated, weatherproof steel housing that allows a substantially low operating noise level of 75 dB. A comprehensive digital control panel provides instrumentation including an AC ammeter, AC voltmeter, frequency meter, AC circuit breaker, engine gauges, and much more.  Unit is available with utility-grade switchgear and can be capable of being paralleled with other like generators or the power grid to offer base load & peak shaving capabilities.

Generator Set Control: 

  • Monitoring:  Sequentially rotating, backlit LCD display of engine hours, engine rpm, DC battery voltage, oil pressure, and water temperature. Includes push button to hold the display on any single parameter.  
  • Protection:  Shutdowns – Overspeed, over crank, high water temperature, low oil pressure, and emergency stop. With an LED indicator for each condition.  
  • AC Metering:  Three-phase volts (L-L), amperes, and frequency with phase select pushbutton, on backlit LCD. Metering accuracy is 0.5%.  
  • Control:  Automatic starting with field adjustable cycle crank, failure to start (overcrank), and cooldown timer.  
  • Programming and Diagnostics Includes field-programmable set-points for engine control and monitoring variables and self-diagnosis of controller system component and wiring failures. 

Alarm Module:   

  • Flashing LED warnings for: low coolant temperature, high coolant temperature (pre-alarm), low oil pressure (pre-alarm), engine control switch not in automatic, and low DC voltage. Includes alarm horn and acknowledge pushbutton. 

Engine Control Switch:
