Alternators and Charge Regulators:
For rapidly recharged batteries
There are two options to solve this issue:
Equip the standard alternator with a Mastervolt
Alpha Pro charge regulator. This charge regulator
maximises the output of alternators by regulating the
alternator in a way that ensures the batteries receive
the optimum charge. The proven 3-step+ charge
method guarantees fast and safe charging of your
You can also choose a powerful second Mastervolt
Alpha alternator with Alpha Pro charge regulator.
This combination was specifically designed for
charging service batteries, and allows you to charge
quickly and turn off your engine when you want.
Suitable for 12 and 24 V.
Including plug & play connection cable, an adapter
cable for Bosch alternators is optional.
The Alpha Pro series is suitable for most alternators
with a charging current of up to 400 amps.
Automatic voltage and temperature compensation.
Keep alive’ function for tachometer.
The charge regulator measures the battery
temperature and adjusts the charging process
accordingly, resulting in a safe and fast charge.
Therefore the battery is always kept in good condition.
Alpha Alternator Series
Fast and complete charging of all batteries.
Power supply for all consumers.
12 V and 24 V versions.
75 A to 150 A charge current.
As standard, delivered with Alpha Pro charge regulator
for an optimal performance and longer-lasting batteries.
Using a Battery Mate, Charge Mate or BI battery isolator
in conjunction with an Alpha Alternator, makes it possible
to easily charge two or three separate battery banks

A second alternator on the main engine, combined
with a larger battery bank and inverter, could be
an alternative for a generator.
The existing alternator on the main engine is designed to charge the starter battery. As a result the
combination is not ideal for fast and full charging of other batteries, especially if you want to charge
the batteries over a short time or when powering a heavy load.
