Generator 23kW 480V: Compact, Powerful, and Versatile

The 23kW 480V generator is a compact and powerful solution designed for contractors and tradespeople in industries such as concrete, masonry, and flooring. Less than one third the size and weight of comparable towable and skid generators, this unit delivers high-performance 3-phase 480V power in a small, portable package. It’s the world’s smallest 3-phase 480V generator in its class, making it a game-changer for those needing reliable, on-site power.

Compact and Dual-Phase Power

Avoid the inconvenience of heavy-duty generators parked far from the work area. The 23kW 480V fits easily into equipment trailers or trucks and passes through standard doorways, allowing you to place it exactly where it’s needed, reducing the risk and power loss from long cable runs.

Advanced Power Technology

This generator features permanent-magnet brushless alternator technology with independent circuits for 120V and 480V. This ensures clean, stable 480V three-phase power that remains unaffected by the load on the 120V circuit, even during simultaneous operation. The advanced alternator provides up to 15% more power from the same engine while requiring fewer components, resulting in reduced wear and a longer lifespan.
