Solar panel with charge controller
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
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!

Stopping the system
Before altering the connections, cover the solar panel with a light
barrier material to stop the electricity production.
First disconnect the consumers, the accumulator may be discon-
nected only after this. Carefully avoid leaving the consumers powered
without a connected accumulator, especially in a sunny day, since
over-voltage may damage the devices!
Maintenance
From time to time clean the surface of the solar panel with a wet
cloth. The accumulated dust, leaves or animal waste can decrease
significantly the performance of the solar panel, which may lead to
unwanted depletion of the accumulator.
Avoid the depletion of the accumulator during the night, or during
dark, cloudy days. Periodically look at the lights on the charge
controller to check the charge level. Recharging the accumulator
needs a lot of power at the expense of the powered devices. Keeping
the accumulator almost charged ensures a long and trouble-free life
of the system.
Using the charge controller
A solar system may not be built without a charge controller. This
component assures the stabilization of the variable voltage gener-
ated by the solar panel, it protects against inverse polarity and
controls the charging process of the accumulator.
The charge controller has multiple working modes. The main elements
of the controller can be identified on the Fig. A, , as follows:
– charge indicator, – charge level indicator, – programmed
output load indicator, – work mode (7 segment display), – work
mode button, and – solar panel connection, and – accumu-
lator connection, and – programmed output (unused), – fixing
holes (Ø4mm).
After the connection of an accumulator, the display shows in
the case of a 12V and in the case of a 24V accumulator. Although
the system works correctly with 24V as well, it is mandatory to build
a12V system!
Attention, do not connect a depleted accumulator as the system is not
powerful enough to start the charging process from the beginning!
Lights on the charge controller
The , and lights are showing essential information regarding
the operation of the system.
Charging indicator
• Off – No charging.
• Continuous green – Charging.
• Slow flashing green – Maintaining the charged state of the
accumulator.
• Fast flashing green – Maintenance mode of the accumulator (buck
charge, desulfation).
Normally this light has to be continuously green.
Charge level indicator
• Flashing green – Maximum charge level.
• Continuous green – Normal charge level.
• Continuous orange – Low charge level.
• Continuous red – Very low charge level.
• Flashing red – The accumulator is depleted.
Normally this light has to be continuously green. When the color
is orange or red, disconnect the consumers for a while to allow
the efficient recharge of the accumulator.
Load status of ( and )
• Off – the output is disabled.
• Continuous red – normal load.
• Slow flashing red – Increased load.
• Fast flashing red – short circuit.
Normally this light has to be off all the time (as we do not
recommend using the output).
