Alpha 24/75 Multigroove is a 24V and 75A alternator from Mastervolt with multigroove pulley. Charge regulator not included

Using a Battery Mate or battery isolator in conjunction with an Alpha alternator makes it possible to easily charge two or three separate battery sets simultaneously.


• Fast & complete charging of starter and service batteries.
• Power supply for all consumers.
• 12 V and 24 V versions.
• 75 A to 150 A charge current.

TIP: A second alternator on the main engine, combined with a larger battery bank and inverter, could be an alternative for a generator.

For all engine types
Alpha alternators are equipped with several fixations for customized alternator brackets, available from your installer or engine supplier. Some engine brands come with Mastervolt alternator brackets as an option.

Fast charging, even at a stationary rpm
Standard alternators only supply the specified capacity at a high rpm. The Mastervolt Alpha alternator is specifically designed for powerful charging, even with a low engine rpm.

Multigroove pulley
The 12/130 and 24/75 models are also available with a multigroove pulley.

Forced cooling by fan operation of the pulley provides a lot of power in higher temperatures, especially close to the engine.
