This super-high-output alternator/generator is all you need to survive, covering all energy needs on your boat.

The simple, bolt-on replacement, 250 amp GenMaax gives you all the output of a large-case alternator in a small case that fits 99% of marine engines. Eliminates or substantially reduces a cruiser’s reliance on solar panels and/or portable generators.

Specifically developed to meet the technical demands of the new generation A.G.M, Lithium and Gel Batteries, the GenMaax 250 super-high-output alternator/generator produces a continuous 195 amps covering most cruisers’ daily energy needs in very short order. More significantly, it also covers very large loads simultaneously.

· Transforms your propulsion engine making it a generator too.
· At idle RPM the GenMaax applies the required load to charge your batteries AND covers additional loads required by other devices.
· Saves space, weight and capital cost that other energy making devices (Solar/Wind/Portable generators) require.
· Part of your existing systems, so no additional systems to maintain.
· Dual internal fans for enhanced cooling.
