48kW1 Commercial Three Phase Generator System

Three Phase

Protect your business from a power outage with a new 48kW1 Commercial Generator System by GE. These three phase generator systems help ensure that, when the power goes out, your business continues to run.

With an industrial grade GM Vortec engine, the 48kW1 Commercial Generator System is designed to meet the rigorous power demands of today's small-to-medium sized businesses. A world-class performer, the GM Vortec 1800 RPM engine provides sophisticated yet extremely durable industrial grade power for years of reliable performance. The low 1800 RPM engine and alternator operating speeds make our commercial generators more fuel-efficient and quieter than typical 3600 RPM engines. Plus, our low operating speeds are designed for longer product life.

Backed by a five-year limited parts and labor warranty2, we're a smart choice for commercial back-up power.
