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,

– charge indicator,

– charge level indicator,

output load indicator,

– work mode (7 segment display),

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!

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).

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.
