Notes: The Projecta IDC25 DC to DC controller fitted in your MDC trailer is programmed to favour the solar panel input
exclusively until it drops below a threshold voltage input. By providing accessory power to the number 12 pin, the trigger
for the IDC25 will be set off to take power from both the An derson plug and the solar panels. It will also trigger the
IDC25 to activate the vehicles ECU to make the alternator provide power to fully charge the multiple batteries in your
camper or caravan.
