Electromaax GenMAAX Super-High-Output Alternators

The Electromaax GenMAAX Super-High-Output alternator is all you need to survive. It covers all the energy needs on your boat and turns your alternator into a powerful energy generator.

The GenMAAX Marine Alternator line is a totally new concept developed at our plant. These small and powerful high-performance alternators have frames manufactured in our CNC plant using 6061 aluminum.

The frames get anodized with a special salt water resistant stainless steel coating that radically enhances heat dissipation which is critical with any alternator over 160amps. The frames are manufactured in-house from billet which allows us to make the GenMAAX a perfect fit on the 3.25″ saddle mount, 4″ J-mount and 1″ and 2″ foot mount engines.

The GenMAAX Super-High-Output alternator is available in 215 Amp and 250 Amp 12V plus 165 Amp in 24V!

Go Overboard with the GenMAAX
Two GenMAAX alternators on one marine engine will generate 338AMPS or 4,722 watts in 12V, on a multi-hull or trawler. Four GenMAAX marine alternators will generate 9,000 plus watts, eliminating the need for portable and or permanent back up generators. Hence the name GenMAAX!

ElectroMaax manufactures 3 mounting types as follows:
• GenMAAX Foot Mount
• GenMAAX J180 Mount
• GenMAAX Saddle Mount

Benefits of GenMAAX Marine Alternators vs. Generator Sets
The GenMAAX was specifically developed to meet the technical demands of the new generation A.G.M, LiFePO4 Lithium, Carbon Foam and Gel Batteries. Read the many benefits of installing a GenMAAX on your engine if you’re considering eliminating or avoiding installing a back-up gen-set – especially when you combine its high output with solar and wind.

• Substantially reduces weight (in a Catamaran this is very crucial)
• Creates more space
• Better utilization of your existing propulsion engine(s)
• Eliminates incoming cold water and outgoing exhaust from the generator set
• Produces continuous power output
• Simultaneously charges your batteries and powers your on-board appliances
• Saves tens of thousands of dollars in replacement and maintenance costs associated with gen-sets
• Transforms your engine into a power generator
• At idle RPM the GenMAAX applies the required load to charge your batteries
• Covers additional loads required by other devices
• Saves capital cost more than other energy generators (solar/wind/portable generators) require
• No additional systems to maintain
• Dual internal fans for enhanced cooling
• Remote rectifier to further dissipate heat and enhance performance
Applies a load at idle that prevents the engine from choking up.
The GenMAAX 165 24 V Super-High-Output alternator produces a continuous 112 amps at 24 volts which covers most cruisers’ daily energy needs, in very short order. More significantly, it also covers very large loads simultaneously.

The simple, bolt-on replacement, 165amp, 24 volt GenMAAX gives you all the output of a large-case alternator in a small case that fits 99% of Yanmar and other marine engines. It eliminates or substantially reduces a cruiser’s reliance on inboard and/or portable generators.
