Scenario 1: The vehicle's main battery is below 12.8V and the DCC is in
Power Saving mode.
If solar power is actively available, the DCC Pro will implement silent solar
charging. The LED Glow Ring will indicate aqua green intermittently. In this
mode the main battery is ignored by the solar charging process and all
available power is dedicated to charging the auxiliary. If there is a load
connected to the auxiliary battery, a fridge for example, the DCC Pro will
attempt to match the discharge rate from the auxiliary battery for as long as
solar power is available. If the voltage on the auxiliary battery drops too low,
the charge cycle will be terminated and the DCC Pro will revert to Power
Saving mode. In silent solar mode the Remote Display is disabled in order to
conserve power however pressing the
button will 'awaken' the display and
OK
the monitor will indicate the auxiliary battery voltage, the charging power in
Watts and display the text SLT SOLAR.
Scenario 2: The main battery voltage is above 12.8V and the DCC Pro is in
a normal charging cycle (boost, absorption or oat).
If solar power is actively available, the DCC Pro will override the current
charging cycle stage and implement primary solar charging (providing there is
su cient power to do so). The LED Glow Ring will indicate aqua green
continuously. In primary solar operation both the main and auxiliary batteries
will be charged simultaneously. Once the main battery voltage has reached
14.5V (or predetermined maximum alternator Voltage) the DCC Pro will release
the main battery and continue to charge the auxiliary battery only. In primary
solar mode the Remote Display is automatically enabled and the monitor will
indicate the auxiliary battery voltage, the charging power in Watts and display
the text PRM SOLAR.
Scenario 3: The main battery is disconnected from the DCC Pro but
remains connected to the auxiliary.
This scenario may occur when the DCC Pro is installed in a caravan or camper
trailer for example, but unplugged from the tow vehicle thereby disconnecting
the main battery supply. If this occurs, the DCC Pro will implement silent solar
charging and it will perform as a stand-alone charging source complete with
MPPT functionality. The LED Glow Ring will indicate aqua green intermittently.
In silent solar mode the Remote Display is disabled in order to conserve power
however pressing the
button will 'awaken' the display and the monitor will
OK
indicate the auxiliary battery voltage, the charging power in Watts and display
the text SLT SOLAR.
