Overview#
The Triton Power TP-NG400-S-K-UL is a 400 kW natural gas standby generator powered by a PSI (Power Solutions International) 20L 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 400 kW standby and 360 kW prime power in three-phase configuration at 120/208V and 277/480V.
The PSI 20L V-16 marks the transition from inline-6 engines to V-configuration powerplants in Triton's natural gas range. The 16-cylinder layout distributes combustion loads across more cylinders, reducing per-cylinder stress and providing smooth power delivery. The unit meets EPA Stationary Spark Ignition emissions standards and maintains 64 dBA sound output. At 400 kW, this generator serves large commercial buildings, industrial facilities, and campus-level backup power applications.
Our service experience#
The V-16 configuration introduces additional ignition system components compared to the inline-6 models lower in the range, but the PSI platform maintains good serviceability with accessible spark plugs and individual coil-on-plug ignition. At 400 kW, gas supply requirements are substantial, and we recommend a thorough gas utility survey before committing to installation. The larger displacement provides comfortable operating margins at rated load.
