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 the batteries require a little more power.
There are two options to solve this issue:
Equip the standard alternator with a Mastervolt charge regulator. This will ensure that the existing alternator works in accordance with the 3-step charge technology instead of its standard 1-step method, and that the batteries are charged faster within a shorter period.
You can also choose a powerful second Mastervolt Alpha alternator with charge regulator. This combination was specifically designed for charging service batteries, and allows you to charge quickly, and turn off your engine when you are at the destination.
The charge voltage is automatically adjusted if there is any risk of gas formation. Electronics permanently regulate the voltage, ensuring that the battery is always kept in good condition.
The Alpha Pro MB is fully connectable to the MasterBus CANBus system, allowing easy monitoring via a MasterView touch screen. In a MasterBus system the voltage drop over the battery cable will be compensated automatically, as well battery temperature, improving the charging time without having to install additional cabling.
Using a Battery Mate or battery isolator in conjunction with an Alpha alternator makes it possible to easily charge two or three separate battery sets simultaneously.
