The already present 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.

You can also choose a powerful second Mastervolt

This combination was specifically designed for
charging service batteries, and allows you to charge
quickly and turn off your engine when you want.

TIP:
A second alternator on the main
engine, combined with a larger
battery bank and inverter, could
be an alternative for a generator.
CHARGE REGULATORS AND ALTERNATORS
For all engine types
Alpha alternators are equipped with
several fixations for customised
alternator brackets, available from your
installer or engine supplier.
Some engine brands come with
Mastervolt alternator brackets as an
option.
Fast charging, even
at a stationary rpm
Multi-belt pulley
Alpha Pro MB:
Easy to operate
Easy operation LEDs on the body of the
regulator indicate the charge phase.
The charge regulator is designed as a
‘fit all’ solution, just one unit is needed
for both 12 and 24 V applications, with
a simple selector switch to set the
regulator to the right voltage. The unit
can also be used on any other brand of
alternator that has a standard Bosch
connector, with a cable supplied as
standard.
The 12/130 and 24/75 models are also
available with a multi-belt pulley.
Performs above 40 °C
MasterBus connectivity
Standard alternators only supply the
specified capacity at a high rpm.
The Mastervolt Alpha alternator
is specifically designed to charge
powerfully, even with a low engine rpm.
The Alpha Pro MB is compatible with
MasterBus, allowing easy monitoring
via a MasterView touch screen. In
a MasterBus system the voltage
drop over the battery cable and the
battery temperature will be
compensated automatically.
Forced cooling by fan operation of the
pulley provides a lot of power in higher
temperatures, especially close to the
engine.
