Mastervolt 48624110 – Alpha Alternator 24/110 with Alpha Pro III Charge Regulator (110A, 24V, Fan-Cooled, Isolated)
The Mastervolt Alpha 24/110 alternator is built for efficient and safe battery charging in demanding marine and mobile environments. Delivering 110 amps at 24 volts, it ensures rapid charging of both starter and service batteries — even at stationary engine speeds. The alternator comes standard with the Alpha Pro III charge regulator for intelligent, multi-stage charging that extends battery life and performance.
This unit is designed for operation in high-temperature engine compartments, with fan-assisted cooling for thermal stability above 40°C. Its isolated electrical design allows for safe integration into systems with Battery Mate or battery isolators, enabling charging of two or three separate banks. Compatible with various engine brackets and suitable as a primary or secondary alternator in generator-free energy setups.
