Charging the Caravan
Mains Power
You caravan will charge from mains power via the Projecta 7 stage charger. Ensure the charger is plugged into its dedicat
-
ed outlet in its bay and is switched on. The factory batteries in your XT16 are AGM and the charger must be set for AGM
batteries.
Solar Power
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 num-
ber 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
Battery Care
Your camper is fitted with 100Ah AGM Batteries. Storage type batteries require periodical maintenance to perform at
their peak and extend their service life. The following is an outline on how to gain the best performance and lifecycle from
the battery fitted in your camper:
• Always use a quality charger that caters to the voltage requirements of an AGM battery. Absorption charging is from
14.6v to 14.8v, float charging is from 13.2v to 13.8v.
• Never leave your battery stored at low volts. Before storing your trailer, ensure that batteries are fully charged, and
all power is disconnected/switched off.
• When possible, leave the battery connected to a smart charger that will cycle and maintain the battery during storage.
If this isn’t possible check and charge at regular intervals to prevent excessive discharge.
• Never use unregulated solar power direct to your batteries.
• When in use try to keep your battery at or as close to maximum capacity as possible.
• Allowing your battery voltage to drop below 12.05v can permanently damage its performance and reduce its service
life.
The batteries are located beneath the bed at the rear of the caravan. State of Charge
