Purpose and function of the
solar panel
The solar panel operates in all daylight
conditions and should prevent the
battery from discharging during periods
of storage (assuming the caravan is
outdoors) and it will enable a much
higher degree of power self-suiciency
if on a campsite without electric hook-up.
Typically, the panel will generate up to
25Ah per day in peak conditions.
There is no maintenance required with
this product, however, it is advisable to
clean the panel with water twice per year
to ensure best performance.

Relay housing
Provides the 12 volt distribution
throughout the caravan. All the fuses are
located at the front of the PDU behind
the lift up cover. Ensure fuses being
replaced are of the rating indicated on
the PDU and never increase the rating of
the fuse you replace.
The system is fully compliant with the
EMC recommendations within the EU.
When the caravan is plugged into the car
the 12 volt’s system will be supplied by
the car except to the refrigerator.
When the car ignition is switched on
and the car is started the system will
automatically switch the 12 volt supply in
the caravan o, then it will connect the
refrigerator 12 volts on and connect the
auxiliary battery to charge from the car.
The car alternator, in this mode,
will only supply the battery with a
small trickle charge.
Please ensure that the voltage supply
at the tow vehicles socket is adequate
enough to supply the fridge.
Connecting electricity testing
RCD
P eriodically it is necessary to test the
operation of the RCD. This is achieved
by ensuring that it is switched in the
ON position with an electricity supply
connected and by pressing the test button
marked ‘T’. The unit should immediately
switch to the OFF position. Provided
this happens all is correct and the switch
should be returned to the ON position,
upwards against the spring pressure,
to restore the supply back to normal.
The RCD also acts as the main switch
for the unit and if it is required to switch
o all circuits in the caravan this can be
achieved by switching the RCD to OFF.
Reverse polarity
When connecting mains supply abroad,
the supply can be of reverse polarity.
The significance of this is that when
equipment is switched OFF it may not
be electrically isolated. The only certain
