Votronic SR 100 Digital Installation And Operating Manual

Installation and Operating Manual
Solar Controller SR 100 Digital
Please read the operating manual thoroughly prior to use, connection and start-up of the solar
controller.
The VOTRONIC Solar Controller SR 100 had been specially adapted to the requirements of the range camper,
caravan and boat, but it is also suitable for other self-contained solar systems. The unit will be connected between
solar module and solar battery, it is designed for 12 Volt systems and it works maintenance-free. An operation in
parallel and floating mode with (automatic) mains chargers, wind power systems or petrol-driven generators at
the same battery is possible without any problems.
Features:
Careful battery charging by continuous operation as pulse-width modulated shunt switching controller.
Operation with lead-acid or lead-gel batteries with a minimum capacity from 12 V / 30 Ah.
Least own electricity consumption in quiescent condition of only 2 mA (0.002 Amperes).
The integrated adapted on-board mains suppression filter ensures unproblematic parallel operation with
the dynamo of the vehicle, mains chargers, wind- and petrol-driven generators etc. at one battery.
Protection against reverse battery and overload by built-in fuse.
Functions:
Reverse Current Protection
1.
The reverse current protection avoids discharge of the battery by the solar module in case of insufficient solar
power (such as during the night). The light-emitting diode (LED) "Charge" is extinguished.
As soon as the solar power is sufficient, the LED "Charge" will be lighting and charging of the battery will be
started.
2. Overcharge protection:
With increasing battery capacity, the solar controller effects an automatic limitation of the battery charging
voltage to the cut-off voltage and decreases the average charging current down to trickle charge current. This
process is indicated by the LED "Full", which will be glowing dimly first and which becomes increasingly
brighter after that, while the brightness of the LED "Charge" will be reduced more and more.
If the battery voltage is reduced by current consumption, automatic charging will be effected
immediately, which is indicated by the two light-emitting diodes. Thus, the battery is always kept on
the best possible charging state.
3. Temperature Control:
Optimum charging is ensured by the temperature sensor being integrated in the SR 100, which effects an
automatic adaptation of the cut-off voltage of the battery to the prevailing temperature.
4. Indicator lamps "Full" and "Charge":
These light-emitting diodes (LED) are indicating the current operating state by varying brightness.
In case of unattended operation, the battery might be totally discharged due to too many consumers
and lack of solar power. We recommend protecting the battery by means of the following appliances:
Votronic
Votronic
Open acid batteries and batteries being „maintenance-free according to EN / DIN":
Store only fully charged batteries and recharge them periodically!
:
Battery Protector 40
Battery Protector 100
Check the acid level periodically!!
Recharge totally discharged batteries immediately!
