Mastervolt Alternator Alpha

Mastervolt Alpha Alpha Compact alternators are optimized to deliver continuous high power output in energy storage applications. Combined with our Alpha Pro regulators, they create a high performance, plug-and-play charging solution. This combination is suitable for all battery types, including Lithium Ion.

Compared to conventional alternators, Alpha Compact offers lower weight, smaller dimensions and reduced fuel consumption. This is made possible by its open construction with double internal fans. An integrated temperature sensor controls the operating temperature. Features

• Plug and play solution, with Alpha Pro III regulator included.
• Up to 40 % lighter and 25 % more compact than conventional alternators.
• Up to 40 % lower fuel consumption.
• OEM quality with optimized material composition.
• Suitable for use in high temperature areas.
• Cable and electronic parts protected against oil, moisture and dust.
