Mastervolt Alpha 12/130 III Multigroove Alternator (48612131) with Regulator
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.
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 kinds of engines
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 with 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 MG model features a multi-groove pulley.
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.
