Generac MLG15M

The Generac MLG15M is a compact, towable single-phase diesel generator built for smaller to midsize mobile power applications. Powered by a Mitsubishi S4L2 four-cylinder, 1.75L Tier 4 Final diesel engine producing 13 kW prime output (14 kW standby), it delivers clean power within ±1% voltage regulation via a Marathon brushless alternator. A 56-gallon polyethylene fuel tank enables an impressive 43-hour runtime at full load, making it dependable for multi-day jobsite deployments. The lockable tubular-steel enclosure with stainless-steel hardware protects components, while automatic low-oil and over-temperature shutdowns add peace of mind. Multiple 120V and 240V receptacles, an external emergency stop, and a DOT-compliant trailer round out a feature-rich package at just 70 dBA.
