Charging from your Vehicle
To charge your caravan effectively while driving you will need to have 12-volt power supplied from your tow vehicle to
a 50amp Anderson plug near your towbar. Wiring and supply should be compatible for 50 amps.
A 12-pin trailer plug is also required. In addition to the standard wiring to pins 1 to 7, power must be supplied to the
number 12 pin for the trigger wire for the IDC25 DCD to DC charger while the engine is running.
•
The IDC25 is programmed to favour the solar power supply until the supply falls below the minimum threshold
for the controller. By supplying power to the trigger wire through the #12 pin, the unit will switch mode to
favour the supply via the Anderson plug when the tow vehicle engine is running.
•
Vehicles that have a “smart alternator” require the IDC25 to be activated via the trigger wire for the ECU to
detect the charge requirement of the trailer batteries
