Charging with Alternator as priority (default)
Once the Alternator input voltage reaches the set
cut-in voltage, charging can begin. The battery
type LED will turn solid and the active charge
stage LED will come on and remain solid, while
the input source LED will continue to flash. Solar
input LED will remain solid while source is
available. The charger will transition through the
different charging stages as previously shown,
until the battery is full.

Charging with Solar as priority - Setting Solar Priority mode
The function of Solar Priority mode is to allow the charger to check for available solar input before
choosing the alternator as the input source. To do this, the charger will assess the state of charge
of the battery and decide if the available solar can effectively supply enough charge or choose the
alternator as the best input source.
The Solar Priority function can be set at any time, once the Aux battery has been connected. To
set Solar Priority, press and hold Solar Priority button for 2 ~ 4 seconds, then realse the button, to
change the priority . The Solar Priority indicator LED will start to flash.
