Alpha 24/150 Evo

  • Fast & complete charging of starter and service batteries.
  • Power supply for all consumers.
  • 24 V 150 A charge current.
  • High charge currents even at low engine rpm.
  • High charge current for longer periods of time.

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

For all engine types

Alpha alternators are equipped with several fixations for customised 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.

Performs above 40 °C

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

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.
