MASTERVOLT Alpha Compact 28/150 Alternator

Elevate your onboard power system with the MASTERVOLT Alpha Compact 28/150 Alternator, the ultimate charging solution for demanding marine and mobile applications. Engineered for superior performance and reliability, this high-output alternator is designed to rapidly and efficiently charge your 24V battery banks, significantly reducing engine runtime, saving fuel, and minimizing noise and wear. It is the perfect upgrade from standard alternators, providing a powerful and consistent energy supply when you need it most.

The Alpha Compact 28/150 Alternator is a powerhouse of energy generation. Specifically designed to deliver a substantial charge current of 150 A at a nominal voltage of 28 V, it ensures your batteries are replenished in a fraction of the time. This makes it an indispensable component for sailboats, yachts, RVs, and commercial vehicles that rely on robust and independent power systems.

Key Benefits:

* Rapid Charging Performance: Drastically cuts down the time your engine needs to run for charging. Its high output, even at low engine RPMs, means your batteries reach full capacity faster, allowing you to enjoy peace and quiet sooner.
* Fuel Efficiency & Reduced Engine Wear: By minimizing engine runtime, the Alpha Compact helps you save significantly on fuel costs and reduces overall wear and tear on your main engine, extending its service life.
* Compact & Lightweight Design: True to its name, the Alpha Compact features a space-saving and lightweight construction, making it easier to install in tight and crowded engine rooms where every inch and pound matters.
* Engineered for Harsh Environments: Built to withstand the rigors of the marine environment, it features a corrosion-resistant finish and is designed to operate reliably at high temperatures, ensuring long-lasting durability.
* Optimized Battery Health: When paired with a Mastervolt Alpha Pro III regulator (sold separately), this alternator provides a sophisticated, multi-stage charging process (Boost, Absorption, Float). This intelligent charging protects your valuable battery bank from overcharging, extends its lifespan, and ensures it is always in optimal condition.
