Description
Alpha Pro III Advanced 3-step charge regulator for standard and high performance alternators The propulsion engine of your boat or vehicles may be used to quickly charge your service batteries, either while cruising or taking a break. The advanced and powerful Alpha Pro III ensures fast and safe charging, protecting both the engine and the batteries.
Building on 10 years of experience, the Alpha Pro III features a modernized look, higher power and improved ease of use. The Alpha Pro III measures the temperature and the voltage of your batteries to prevent overcharging, keeping them in perfect condition.
It also monitors the engine load, thus reducing sound variations, wear and tear. The smart ‘keep alive’ feature solves a common problem causing unreliable tachometer readings.
Via MasterBus, it communicates RPM, alternator status and charge status to create intelligent power systems. Pull the max out of your alternator The alternator that comes with the engine is not optimally suited for charging service batteries.
Designed for low cost and short charge cycles, it charges at a slow pace and is easily overheated. Replacing the standard regulator* with the Alpha Pro III optimizes this charging process, protects against overheating and overcharging and extends the lifetime of your batteries.
(* not allowed on Euro 5/6 engines) Super charge your system For superfast charging at low RPM, Mastervolt recommends to combine the Alpha Pro III with a high performance alternator such as the reputable Alpha series. With 20 amps of field current capability, the Alpha Pro is the only 3-step regulator in the market capable of controlling alternators with outputs up to 400 A!
Alpha Pro III: Fast charging, anytime, anywhere. Features: Transforms every alternator into a full temperature controlled 3-step charger.
Reduces run time, saves fuel, reduces noise and emissions. Protects from overcharging and extends battery life.
Balances engine load, reducing RPM variations. Compatible with

Electrical — frequently asked
- What’s the difference between marine wire and regular wire?
- Marine wire uses tinned (tin-coated) copper strands that resist the corrosion salt air causes, and it’s more finely stranded so it flexes with vibration without breaking. Standard automotive or household wire corrodes and fails much faster in a marine environment.
- How do I size a fuse for a marine circuit?
- Size the fuse to protect the wire, not just the device. Match the fuse rating to the wire gauge’s safe current capacity so the fuse blows before the wire overheats. When adding a new circuit, follow the wire manufacturer’s ampacity chart for the gauge and run length you’re using.
- Do I need a battery switch on my boat?
- A marine battery switch is strongly recommended. It lets you disconnect the battery for storage or service, isolate a failed battery, and — on multi-battery setups — choose which bank powers the boat. It’s a core safety and reliability component.
