The NautiVolt 5000™ is a revolutionary variable-speed, variable-output generator that runs directly off your main engine, delivering 3.5 to 5kVA of clean 240V AC power at any RPM. Enjoy the comforts of home without the noise, space, and maintenance of a separate genset.
Our system automatically adjusts power generation to match demand, from 3.5kVA up to a full 5kVA. This smart power management drastically reduces fuel consumption and engine load.

Unlike traditional belt-driven systems that demand a fixed engine speed, the NautiVolt 5000™ delivers pure sine wave 240V/50Hz power across your engine's full operating range. Throttle up or down; your power stays rock solid.
