SMARTPASS
SMARTPASS can operate as a stand-alone unit, but works best in combination with D250S
DUAL. The SMARTPASS creates a priority path for charging the Service battery to recharge
it more quickly and efficiently. Attached energy sources like solar, wind or shore power will
charge both the Service and the Starter batteries through the SMARTPASS. Service batteries
that are overheated due to age, high ambient temperature or other battery problems will be
protected from high alternator current.
SMARTPASS
FEATURES:
The CTEK SMARTPASS adds additional functionality for higher output alternators, larger battery
banks and/or high parallel loads.
