Alpha Compact 12V/120A alternator with Alpha Pro III load controller - Mastervolt

The Alpha Compact alternators are ideally designed to provide a high current to the electrical storage components at all times. Combined with Alpha Pro controllers, they form a plug-and-play solution to load. This combination is suitable for all types of batteries, including Lithium Ion.

These motor type alternators offer several advantages. Most engine manufacturers offer an option for a second alternator, often referred to as a force-taking option. This is a direct way to easily add an Alpha Compact as the second alternator. The original alternator can also be replaced by an Alpha Compact to benefit from a powerful 3-step charger connected to the MasterBus network.

Plug-and-play solution, with Alpha Pro III controller included.
