Mastervolt Alpha Pro III 45513000

Three-stage electronic charge controller for standard and high-efficiency alternators.

The engine of your boat or vehicle can be used for rapid charging of the service batteries, whether while navigating or during parking. The powerful Alpha Pro III ensures fast and safe charging, protecting both the engine and the batteries. Based on 10 years of experience, the Alpha Pro III features an updated design, higher power, and improved usability.

The Alpha Pro III measures the temperature and voltage of your batteries to prevent overcharging, keeping them in excellent condition. It also monitors the engine load, reducing fluctuations in sound, wear, and stress. The smart 'keep alive' function addresses a common problem that causes unreliable RPM readings.
