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elds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 efciently. The automatic charging
process preserves the device and does not
overchargethebatteries.Thisinturnextends
the service life of the batteries signicantly.
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.
