SOLAR DUAL BATTERY CHARGER
i
ntroduction
The solar module/panel generates power
when light is cast upon it. 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 with a capacity of 50-100Ah (SDC
10) or 50-200Ah (SDC 20) (e.g. leisure battery).
The preferred application fields for the
automatic charger are batteries with gel, AGM
(Absorbed Glass Mat) or liquid electrolyte.
f
unction
The device has a modern microprocessor-
controlled pulse with a 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, 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.
Please observe the maximum voltage
and power consumption values.

The device has 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 required end voltage
is reached.
Absorption phase
The charging current is kept for a period of 2
hours. At the end of this period, it changes to
the float phase.
Float phase
The charging voltage is set to 13.8v. The
charging current drops to the value necessary
to compensate the self-consumption of
the battery. Power is still supplied to the
attached consumer units. If the consumed
current exceeds the available solar charging
current the charging process can no longer be
maintained. If the battery voltage drops below
13.3 V, the device automatically switches to the
bulk phase if there is adequate solar charging
current.
Equalisation charging phase
Only for AGM and liquid electrolyte
battery type
The equalisation charging phase serves to
compensate the cell voltages and can reduce
any sulfation. If the voltage of the battery
drops below 11.1 V, it is assumed that the
battery has deep-discharged. The device is
switched to the equalisation charging phase for
two hours. At the end of this period, it changes
automatically to the float phase.
