A solar charger system is a perfect solution on remote locations
where the 230 V mains is not available. The system is intended to
charge an accumulator, which powers an electric fence energizer, an
illumination system, or other, 12 V, low power consumers, such as
mobile phone chargers, FM-transmitters, etc.
Installation
The system is shipped as partially assembled. Length of the cables:
• Solar panel ↔ Charge controller – 5 m.
• Charge controller ↔ Accumulator – 1 m.
It is quite simple to install the system (Fig. C) – the solar panel has to
be mounted facing toward south and tilted in 45 degrees. Make sure
that no shadows are cast on its surface during the day. These three
conditions must be met. It is also recommended that the supporting
EN
structure be as high as possible. The panel can be fixed through the
holes on its aluminum frame.
The charge controller must be installed in a place free of moisture
(water droplets, rain, snow), as the primary source of failure is mois-
ture. The solar panel can serve as a cover for the charge controller as
its operation is not affected by weather and humidity.
Keep in mind that the solar panel produces electricity even in
low light, therefore avoid short circuits during handling and
installation! To prevent damaging the solar panel or the charge
controller, keep the solar panel covered with a light barrier
material until the installation is complete!
When extending the wires, be sure, the contacts are flawless
and the insulations are perfect. In the case of replacing the
wires, pay extra attention to fastening the screws on the charge
controller – those screws are quite small, strong fastening can
lead to broken threads.

Accumulator
Use a 12 V acidic or gel accumulator to store the collected energy.
Attention, the package does not contain the accumulator! Do not use
other types of accumulators, such as Li-Ion or Ni-MH.
A high capacity accumulator may be used, but we recommend
a maximum value, depending on the power of the solar panel, since
in the case of the total depletion of the accumulator the system may
be unable to restart the charging. The recommended maximum accu-
mulator capacity for the given solar panel is as follows:
• 30 W panel – max. 70 Ah.
• 50 W panel – max. 100 Ah.
• 100 W panel – max. 200 Ah.
Connect the accumulator to the charge controller by the included
clamps (Fig. B).
• Red clamp = positive lead (
�
• Black clamp = negative lead (
Starting the system
In the first step connect the accumulator (Fig. B).
In the second step, check the lights on the charge controller to deter-
mine the correct operation of the system (study the „Lights on the
charge controller" chapter below).
In the last step connect the consumers to the accumulator (electric
fence energizer, lighting system, etc.).
Avoid connecting the consumers without a connected accumu-
lator, as you risk damaging the devices! Depending on the light
strength, the output voltage of the system can vary greatly. For
example, on a sunny day, without a connected accumulator, the
output voltage of the system can be as high as 22 V, which obvi-
ously will damage any consumer that has a nominal powering
voltage of 12 V!
