The Module ALTERNATOR-IN enables the on-board batteries to be charged while driving with the help of the alternator. Both from 12V on-board network (starter battery) to 12V living area voltage, as well as from 24V to 24V, from 24V to 12V or even vice versa.

Depending on the variant required, the module contains a Votronic VCC or Victron Energy 2b2 charging booster with suitable charging characteristics and temperature control - tailored to your alternator and on-board batteries.

Further components of the module

The Module ALTERNATOR-IN also contains fuses for the input and output sides that are dimensioned to match the performance of the charging booster, plus one replacement fuse each. A suitable fuse holder is also included - of course in a splash-proof design for installation in the engine compartment on the inlet side. The replacement fuse fits into the cover of the respective fuse holder and is therefore in the right place and always at hand.

To protect the batteries, a semiconductor switch controlled by the battery management is included in the package in the respective ALTERNATOR-IN Module, which can be configured via Bluetooth and, if necessary, even switched. This enables the BMS to switch off the entire charging branch of the alternator if necessary, in order to protect the storage unit from overvoltage, for example.

Compatible with all other charging modules

The Module ALTERNATOR-IN can be combined with other charging modules such as SOLAR or 230V-IN.
