ANOTICE!
•Check the manufacturer‘s data for your battery and ensure that the
maximum voltage of the solar charge controller does not exceed the
manufacturer‘s recommended charging voltage.
•Do not use the solar charge controller to charge non-rechargeable
batteries.
•Be sure to connect the battery before exposing the solar panel to the
sun.
•Before using the device for the first time, check that the voltage speci-
fication on the rating plate matches that of the power supply.
•Store the device in a dry and cool place.
2.2 Safety when installing the device
!WARNING!
•The electrical installation may only be connected by qualified person-
nel and only in accordance with the national regulations. Incorrect
connection may cause severe hazards.
•Take the precautions necessary to ensure that children cannot inter-
fere with operation. Dangerous situations may occur which cannot be
recognised by children.
ANOTICE!
•Do not expose the device to a heat source (direct sunlight, heating
etc.). Avoid additional heating of the device in this way.
Electrical cables
!CAUTION!
•Lay the cables so that they cannot be tripped over or damaged.
ANOTICE!
•If cables have to be fed through metal walls or other walls with sharp
edges, use ducts or bushings to prevent damage.
•Do not lay cables which are loose or bent next to electrically
conductive material (metal).
•Do not pull on the cables.
•Do not lay AC cables and DC cables in the same duct.
•Fasten the cables securely.

2.3 Operating the device safely
!WARNING!
•All lead acid batteries produce harmful and explosive gases. The
battery should be mounted in a well ventilated area, as far as possible
from any ignition source. Do not smoke when in the vicinity of the bat-
tery under charge.
ANOTICE!
•Do not disconnect any cables when the device is still in use.

4 Intended use
The SC1230-PWM solar charge controller (ref. no. 9600005819) can be installed in
motorhomes or caravans to be connected to solar panels to charge house batteries.
The device may only be used inside the vehicle.
5 Technical description
The SC1230-PWM solar charge controller enables mobile power supply from solar
panels for 12 Vg/24 Vg devices and two USB devices. The devices can be
simultaneously supplied with power while the 12 Vg/24 Vg battery is being
charged.
The solar charge controller ensures that the power supplied by your solar panels is at
the right voltage to charge your home or auxiliary battery. The solar charge controller
is PWM controlled. It is an intelligent 3 stage solar controller.

Solar charge controller
The solar charge controller has the following functions:
•PWM controlled
•Three stage charging (Bulk, Boost/Equalize, Float)
•Battery types selectable: Sealed, Gel, and Flooded
•LCD display dynamically displaying operating data and working condition
•Two USB output ports (maximum output 2.4 A) as power supply charge for
electronic equipment
The solar charge controller has the following protective functions:
•Incorrect polarity protections for solar module and battery
•Battery overvoltage protection
•Battery overheating protection
•Battery over-discharge protection
•Load overload protection
•Load short circuit protection
•Controller overheating protection
Battery temperature sensor (available as an accessory)
The battery temperature sensor allows the solar charge controller to continuously
adjust charge voltage based on measured battery temperature. Temperature com-
pensation of charge voltage assures that the battery receives the proper charge volt-
age as battery temperature changes during normal operation.
