IVT SCplus Notice D'utilisation page 12

Always ensure proper ventilation of your solar controller. Never cover the ventilation slots of the solar controller. Never use the
•
device in the vicinity of highly flammable materials.
Remember that large amounts of energy are stored in batteries. In case of short-circuit, these energy quantities can be
•
released in a short time. This means that extreme heat may built up or a fire may break out at the site of short-circuit.
Attention: All components (solar module, battery, consumers and solar controller) must be adjusted to each other concerning
voltage and intensity of current. Check this information on the respective type plate. In case of doubt, please contact your
dealer. Strictly ensure correct polarity!
Important notes:
In case of reverse polarity on the load output, devices without own protection may be destroyed. This is why each
•
consumer must be protected individually.
To ensure safe operation, please strictly pay attention that you observe the correct order, when connecting the
•
individual system components.
Connection sequence:
1. Connecting the battery
Connect the battery at the provided screw type terminals (11) on the solar controller. In order to keep the voltage drop and the
related cable heat-up as low as possible, we recommend using an appropriate cable diameter. The terminals are designed for
mounting cross-sections up to 16mm².
The required minimum cross sections are: 1.5 mm² up to 15 A, 4.0 mm² up to 25 A, 10.0 mm² up to 40 A.
•
Make sure that the line between battery and solar controller is fused according to instructions.
•
Battery and solar controller must be installed in the same room in a small distance.
•
2. Connecting the solar module
Connect the solar module at the provided screw type terminals (12) on the solar controller.
3. Connecting the load
Finally connect the DC load to the load output (10) of the solar controller.
Perform the configuration according to the symbols on the solar controller or the illustration (see connections and operating
elements).
Notes:
Please observe correct polarity when connecting the DC consumers!
•
Make sure that the load output of the solar controller is switched off!

Deep discharge protection
Solar batteries must be protected against deep discharging, because it may lead to irreparable damages. The solar charge controller
offers reliable protection for the batteries against deep discharging by switching off the connected DC load as soon as the discharge
voltage has been reached. As soon as the batteries have sufficiently been recharged over the solar cells, the load output is automatically
switched on again depending on the presets.
Overcharge protection
If the max. charge voltage has been reached, the battery is not fully charged yet. Then the load current is reduced so that the max.
charge voltage will not be exceeded. This procedure charges the battery in a gentle and fast manner without overcharging it.
Temperature compensation
The temperature probe provides optimum adjustment of the max. charge voltage to the ambient temperature of the battery. For this
purpose the controller and battery should be in the same room.
Voltage sensor for battery
Use the supplied connection adapter to connect the "battery sense" connector (13) to the battery terminals to enhance the precision of
the function of the solar charge controller.
