20. UNICORN
BATTERY CHARGER SDC 10/20
The solar module generates power when light
is cast on it. The full voltage is also available
even if there is little light. The solar automatic
charger only serves to charge 12v (24v) lead
accumulators comprising 6 (12) single cells
(e.g. caravan battery) with a capacity of 50-
100Ah (SDC 10) or 50-200Ah (SDC 20) The
preferred application fields for the automatic
charger are batteries with gel, AGM (Absorbed
Glass Mat) or liquid electrolyte.
!
The device is not suitable for charging:
• 6v batteries or 6v lead accumulators
• Non-chargeable batteries
• Nickel-cadmium batteries
The device is only suitable for regulating solar
modules. Do not connect any other voltage
sources (e.g. main voltage 230v) to the device.
This may destroy the device and/or sources. If
any other voltage sources are used together
with the device, please ask your retailer.

Function

The device has a modern microprocessor-
controlled pulse with modulated three-
phase charging characteristic. This allows
high performance combined with a light
weight and small dimensions. By virtue
of the high-quality electronics, it works
highly efficiently. The automatic charging
process preserves the device and does not
overcharge the batteries. This in turn extends
the service life of the batteries significantly.
It is suitable for batteries with liquid, gel or
AGM technology and has a settable charging
current distribution for two separate battery
connections.
The device is designed for continuous
operation and parallel mode. Consumers can
be continuously connected, switched on or
disconnected. Consumers are supplied and the
batteries are charged at the same time. The
consumer current here should be smaller than
the solar charging current as otherwise the
battery will not charge.
If the device is operated in conjunction with
an external temperature sensor for the supply
battery (battery 1), the device regulates the
charging voltage automatically depending
on the battery temperature. This ensures
particularly effective and gentle charging of
the battery. If an external temperature sensor
is not used, the device regulates the charging
process based on the internal temperature
sensor.
The supply and starter batteries can be
charged by connecting one or several solar
modules. Please observe the maximum
voltage and power consumption values.

Charging process

The device has an electronic reverse voltage,
reverse current and solar short-circuit
protection. The charging current is only
released if the battery is connected correctly
and there is enough power available from
sunlight. When a temperature sensor is used,
charging takes place on a temperature-
dependent basis.

Bulk phase

Charging with maximum available solar
charging current until the charging end
voltage is reached.
