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).
