Charging the Caravan
Mains Power
The Projecta charger in your caravan is connected via the 15A exterior socket. To
use site power, you will require a 15A power lead connected to a 15A outlet
(figure 1). In the event a 15A outlet is unavailable you will need a conversion box
that will step up from 10A to 15A with a safety switch. Never leave power leads
coiled when in use, lay the lead out back and forward in a manner that won’t be a
trip hazard or risk damage to the lead.

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.
V ehicles 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.
