Plug Type – 50 amp Anderson Plug
Vehicle with or without smart alternator:
The Anderson plug can be connected to the start battery on the vehicle and should include the following to protect
the start battery.
1. 50 amp relay to stop power supply when vehicle is not running
2. 50 amp fuse or circuit breaker at the battery
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 Anderson 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 Caravan.
