Overview#
The Triton Power TP-NG500-UL is a 500 kW natural gas standby generator powered by a PSI (Power Solutions International) 22L turbocharged V-16 engine running at 1800 RPM. This unit is part of Triton's EPA-certified natural gas generator lineup, UL2200 listed for the US and Canadian markets. The Leroy Somer Class H insulation alternator delivers 500 kW standby and 450 kW prime power in three-phase configuration at 120/208V and 277/480V.
At 500 kW, the TP-NG500 enters the range where healthcare and data center applications become relevant. The PSI 22L V-16 provides the displacement and cylinder count for sustained high-output operation on natural gas fuel. The unit meets EPA Stationary Spark Ignition emissions standards and maintains 64 dBA sound output. PSI engines are designed from the ground up for gaseous fuel combustion, with hardened valve seats and optimized ignition systems.
Our service experience#
The 500 kW class is a key specification point for large commercial buildings, healthcare facilities, and data centers. The PSI V-16 platform at this output level requires attention to cooling system capacity and gas supply infrastructure. We recommend annual load bank testing to verify performance under full load, as natural gas generators that run only during brief utility outages may not reach full operating temperature during normal exercise cycles.
