The 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.
By removing the rectifier out of the alternator and replacing it a few feet away attached to a large heatsink that has a cooling fan attached you substantially reduce the heat issue associated with higher output alternators. Removing the internal rectifier also increases the airflow around the stator/rotor also assisting in heat dissipation.
The GenMAAX Marine Alternator line is a totally new concept developed at our Canadian plant. These powerful high-performance alternators have frames manufactured on our CNC machines in our Canadian plant using 6061 aircraft aluminum.
The GenMAAX Super-High-Output alternator is available in 215 Amp and 250 Amp 12V output. The 250 AMP 12 v and the 165 amp 24 v are both remote rectified plus.

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!

The frames get anodized with a special salt water resistant 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 215 amp alternators were specifically developed to meet the technical demands of the new generation A.G.M, LiFePO4 Lithium, Carbon Foam and Gel Batteries in small banks. The 250 amp Remote rectified alternators are intended for larger Battery banks, especially Life Po 4. 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.
The dual posts on the alternators back now makes the unit isolated ground. Plus makes the alternator compatible with either P or N type regularors. Also, no heavy ground cables needed.
Applies a load at idle that prevents the engine from choking up.
The GenMAAX 165 24 V Super-High-Output Remotely rectified 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 12 V 250 amp version has similar output current but in 12 volts.
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, Volvo Penta and other marine engines. It eliminates or substantially reduces a cruiser’s reliance on inboard and/or portable generators.
Remote Rectifier
For boaters with large battery banks – especially Lithium batteries – ElectroMaax has introduced a remote rectifier to our GenMAAX Super-High-Output alternator 250A 12 V and 165A 24 V models.
Remote rectification has been in use for decades in industrial applications. With the advent of new highly advanced battery technology like our LiFePO4 Advanced Technology Marine batteries, Crystal lead plus super A.G.M like now entering the marine market, these multi benefit features resolve or minimize most of the alternator issues created by these new battery types.
Removing the rectifier out of the rear part of our GenMAAX 250 12 V and the 165 24 V alternators and placing it a few feet away, has many benefits.
The Key Benefits are listed below
By far the single biggest benefit is that over 50% of the heat has been removed from the alternator. Only the heat generated by the stator remains.
In addition, the air space now available due to the removal of the rectifier which allows the twin fans attached to the rotor to work more efficiently by greatly enhancing heat dissipation too.
To further enhance cooling the housing is aluminum and acts as a heat sink.
With the remote being up to 48” away from the alternator and engine, the device can be located next to the batteries in a generally more cooler and dryer place. Now there are no connections needed at the back of the alternator.
In essence we are splitting the alternator in half. This allows for the output of a large frame alternator in a small case alternator frame.
Due to no wiring at the back of the alternator (now done at the face of the Remote Rectifier) makes the wiring hookup much simpler too.
The remote rectifier is three times larger than the bridge rectifier which is found in the standard GenMAAX. The increased number of diodes greatly reduces thermal falloff which is the general cause of reduced power transfer as the alternator (stator rotor) heats up.
As a result, the hot and cold ratings are substantially improved in both cases.
All marine alternators that are subjected to 50% of normal internal heat generation will last significantly longer.

Only a small field wire and a ground post are located on the back of the alternator, all other connections are on the Remote rectifier simplifying installation.
