Alternator Charger and Battery Isolator
While driving, your Roadtrek will also charge the coach batteries from the vehicle alternator through an isolator. The isolator
allows extra vehicle alternator-produced electricity to charge your coach batteries in addition to keeping your engine
(chassis) battery charged. When the vehicle engine is not running, it breaks the electrical connection between your coach
batteries and your engine battery, so your engine battery remains charged to start your engine even though you are using
coach battery power while camped. This is all automatic - there are no user adjustments possible to the isolator.
Optional Solar Panels
The optional solar panels will charge your batteries when
sufficient sunlight is available. The solar charge controller is
installed at the factory for the type of panels and batteries
installed on your vehicle, and Roadtrek strongly recommends
that you make no adjustments or changes to the charge
controller or its programming. The charge controller usually
displays either system voltage or amperes generated by the
panels.
