Overview#

The Triton Power TP-K30-T4i-UL is a 30 kW diesel standby generator powered by the Kubota V3300-E3BG-CHN-1 naturally aspirated four-cylinder engine (3.3 L displacement) with a Leroy Somer LSA42.3VS3 alternator. It carries UL2200 listing and is configured as three-phase only (30 kW at 277/480V, 120/208V, or 120/240V). No single-phase configuration is available on this model.

The unit uses a Deep Sea Electronics controller (DSE4520 or DSE4510 standard, with DSE73XX/74XX autostart and DSE86XX synchronization models available). Fuel consumption is 9.1 L/hr (2.40 GPH) at full load, dropping to 4.6 L/hr (1.22 GPH) at half load.

Our service experience#

The Kubota V3300 engine platform is a proven workhorse in the 25-40 kW class, shared across many generator brands. Its naturally aspirated design means fewer emission-control components compared to turbocharged alternatives, which translates to simpler maintenance in the field. In Northern California, 30 kW three-phase units serve small commercial buildings, restaurants, and branch offices. The Kubota engine's reputation for reliability and the global parts availability through Kubota dealers make this a solid choice for budget-conscious standby installations.
