Predefined charging characteristics: Lead-acid , lead-gel, lead-AGM, LiFeP04
For the pulse-width modulated, serial charge controllers, 4 different charge programs are predefined, specially adapted to the respective battery type: Lead-acid, lead-gel, lead-AGM as well as LiFePO4

User-programmable charging characteristics
In addition, a user-specific charging process can be programmed. A connection between the solar controller and the PC can be established using the USB interface. via the PC, the factory settings on the solar controller can be conveniently changed using the Windows software. Furthermore, the operating data of the solar system can be recorded, stored and evaluated.
With the SCDplus solar controllers, programming and reading of live parameters is possible on the device.

System voltage 48 V
The SCDplus 40 A solar charge controller is designed for a system voltage of 48 V

Automatic temperature compensation
During the charging process, the temperature is measured via the external temperature sensor and thus the charging end voltage is dynamically adjusted to the temperature conditions. At high temperatures, the charging end voltage is reduced - overcharging and unnecessary gassing are avoided. At low temperatures, the charging end voltage is increased.

Voltage sensor for battery
An even more precise operation of the solar controller is possible due to the integrated voltage sensor connection. Through the cable between the solar charge controller and the battery, the battery voltage is measured even more precisely. This enables even more precise charging.

Multi-stage charging technology - matched to battery type
Depending on the defined battery type (factory setting: lead-acid battery) and its end-of-charge voltage, charging takes place in up to 3 stages. In charging stage 1, charging first takes place with maximum current until the corresponding final charging voltage is reached. The end-of-charge voltage of charging stage 1 is then maintained for a defined period of time before switching to charging stage 2, the trickle charge. The charging current is limited according to the principle of pulse width modulation (PWM).
Both the charging profile for LiFePO4 batteries and the user-defined one still offer a third charging stage.

Switchable standby function
A standby function is integrated in the SCplus-/SCDplus solar charge controllers. In case of insufficient solar power, the solar charge controller switches to standby mode. The solar charge controller's own consumption is thus reduced by up to 40 %. This protects the connected battery and prevents unnecessary discharge. If sufficient solar voltage is present, the solar charge controller automatically returns from standby mode. In addition, the solar charge controller can be brought out of standby mode manually by pressing a button.

Programmable and switchable load output
Many individual settings can be made for the IVT solar controllers of the SCplus-/SCDplus series. The load output is individually programmable
The following options can be set for the load output:
1. Timer function: Load output switches on or off at the defined times.
2. Night light function: If there is no solar power, the load output switches on after 2 minutes; if solar power is present, it switches off again.
3. Automatic switch on/off: When the end-of-discharge voltage is reached, the load output switches off automatically. As soon as the restart voltage is reached, it switches on again.
4. Permanently off: When the end-of-discharge voltage is reached, the load output remains permanently off, even after the battery capacity has reached the reset voltage again (factory setting). The load output can also be switched on or off manually by pushbutton.

LED status display
2 LEDs quickly and reliably indicate the current charge level, warn of deep discharge and indicate the status of the load output.

Illuminated LCD display and convenient operating keys
Special feature SCDplus solar controller: Clear display - easy operation
The SCDplus controllers also have a clear and well-structured LCD display. It provides information on the most important parameters such as system voltage (12 V, 24 V or 48 V), solar input (energy meter), battery status (battery voltage, state of charge, charging current), ambient temperature, set temperature coefficient and load output (load current).
The following parameters can be configured via the display:

• Charging method
• Discharge voltage
• Reset voltage
• Temperature coefficient
• Load output (reclosing yes/no, timer and night light function)

Extensive protection functions
all important protective functions such as overcharge protection, deep discharge protection and reverse polarity protection are controlled fully automatically and without monitoring via the microprocessor.
Protection against overcharging: As soon as the final charging voltage is reached, the solar charge controller switches off the charging current. This prevents overcharging and damage to the solar battery.
Deep discharge protection: To protect the battery from irreparable damage in case of deep discharge, the connected load output is switched off when the final discharge voltage is reached. Depending on the setting of the load output, it remains switched off or is switched on again automatically if the battery has been sufficiently recharged. The end-of-discharge voltage and reset voltage can be individually parameterized via the display or the software. An optical warning (LED) is given shortly before the deep discharge limit is reached.
Short circuit and reverse polarity protection: The controllers are protected against short circuit by a flat fuse and protected against reverse polarity.

Parameterization, monitoring and evaluation via PC
Parameterization and monitoring of the solar controller via PC: With the help of the USB interface, a connection can be established between the solar controller and the PC. With the Windows software, the charging profile, deep discharge protection, temperature coefficient, function of the load output, time and date can be configured conveniently on the PC. In addition, the operating data of the solar system can be logged, monitored and output as a *.txt file for evaluation.

The following parameters are recorded every second

• Time (Time)
• Battery voltage (Voltage)
• Battery charge current (Charge current)
• Load current
• Temperature (Temperature).
