USA-Made Quality and Engineered Performance

This generator is 100% designed, engineered, assembled, and tested in the USA, built around a rugged Perkins 2806F-E18TAG1 engine. It’s turbocharged, aftercooled, and liquid-cooled with electronic governing for optimal performance. The brushless Leroy Somer TAL-047-D alternator with AREP excitation and DeepSea DSE7320 MKII controller ensures reliable output, while digital voltage regulation with motor soft-start capability adds extra versatility.

Advanced Rental-Grade Features and Safety

The system includes a 600-gallon double-walled fuel tank offering up to 23 hours of autonomy at 75% load. A manual voltage selector switch allows effortless toggling between 1-phase and 3-phase voltages, and the rental-grade power distribution panel includes GFCIs, twist-locks, camlocks, and bus bars. Key safety components include emergency stop buttons, earth leakage relay, battery disconnect, and breaker shunt-trip protection.

Marine-Grade Enclosure and Superior Acoustic Control

Housed in a 12-gauge marine-grade aluminum enclosure, this generator features excellent sound attenuation and marine-grade corrosion resistance. Up to 50 mm of Polydamp® acoustical foam ensures whisper-quiet operation that meets U.S. and EU sound level directives. External ports, LED lighting, shore power access, and protective coatings round out a system built for longevity and low maintenance in the harshest conditions.
