GenMaax Super-High-Output Marine Alternator Generators

Faster charging at the appropriate voltage means you use less fuel and increase the life of your batteries.

Benefits of the GenMaax Line of Super-High-Output Marine Alternator/Generators

Today’s batteries, like AGM, Gel and Lithium require a specific voltage when charging, and since that is a feature no internal regulator can offer, we recommend you couple the GenMaax with the EMaax Smart, Exterior Regulator.

The combination of these two technologically advanced products charges batteries much faster and increases the longevity of your battery bank.

The GenMaax alternator/generators not only produce continuous power output, sufficient to simultaneously charge batteries and power on board conveniences at low RPM and for a very long time without suffering any degrade, but do so while sustaining temperatures of 55C.

Faster charging at the appropriate voltage means you use less fuel and increase the life of your batteries.

12 volt GenMaxx alternator/regulators are available with your choice of internal or external regulators.
24 volt GenMaxx alternator/regulators are available with external regulators only.
