Marine Generators Manufacturers

The marine generator is a generator fixed in boats or yachts and provides backup power to satisfy various electricity demands such as lighting, air conditioning, and other electric appliances.

We specialized in developing and producing silent marine generators ranging from 3kw to 50kw and customization is also available. Our unique inverter technology enables us to make the smaller, lighter, more compact, quieter, and more efficient generators in the world. Driven by worldwide renowned diesel engines such as Yanmar or Kubota, Sleeper marine generators perform extremely stably and reliably. The small and compact design of the generators makes them only need minimal space onboard for installation. A water-cooled diesel engine and alternator in a specially designed sound shield make the generators extremely silent and have low vibration levels.

Our aim is to provide the more reliable and quiet marine power generators for both recreational and commercial vessels and yachts. A sleeper marine generator is your better option for electrical systems on yachts and boats.
