High quality solar controller series –
Individual charging, extremely efficient and reliable

The high-quality serial SCplus-/SCDplus solar controllers from IVT are characterized above all by their versatility. They offer you 4 predefined charging characteristics that are optimally matched to all common battery types.

In addition, their load output has various special functions that can be set individually. In addition, certain charging parameters can be programmed via the free software and the data can be evaluated.

Serial charging regulation System voltage 12 V/24 V DC Switchable load output 12 V/24 V DC Suitable batteries: lead-acid, lead-gel, AGM and LiFeP04 Timer function Nightlight function PC interface CE 3 years warranty Made in Europe

Important characteristics and features

Predefined charging characteristics: Lead-acid, lead-gel, lead-AGM, LiFePO4

+
For the pulse-width modulated, serial charge controllers, 4 different charge programs specially adapted to the respective battery type are predefined:
 
  • Lead-acid
  • Lead-gel
  • Lead-AGM
  • LiFePO4

User-programmable charging characteristics

+
User-programmable charging characteristics

In addition, a user-specific charging process can be programmed.

The USB interface can be used to establish a connection between the solar controller and the PC. 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.

Automatic detection of system voltage 12 V/24 V

+
The SCplus/SCDplus solar charge controllers can be used for 12 V or 24 V systems. The system voltage is determined automatically.

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 end-of-charge voltage is reduced – overcharging and unnecessary gassing are avoided. At low temperatures, the charging end voltage is increased and the batteries can be optimally recharged.

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 accurately. This enables even more precise charging.

Multi-stage charging technology – Matched to the battery type

+
Depending on the defined battery type (factory setting: lead-acid battery) and its final charge voltage, charging takes place in up to three 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 predefined 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).

The user-defined charging profile still offer a third charging stage.

LED Status indicator

+
2 LEDs indicate quickly and reliably the ongoing charging step, warn of deep discharging and show the state of the load output.

Switchable standby function

+
The SCplus/SCDplus Solar Controllers offer an integrated standby function. In the case of insufficient solar power the solar controller switches into standby mode. This way, the internal current consumption of the solar controller is reduced by up to 40 %.

With this, the connected battery is preserved and unnecessary discharging prevented. If sufficient solar power is available the solar controller returns to active mode automatically. Furthermore, the solar controller can be switched into active mode manually via push 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.
    off again when solar power is present.

3. Automatic on/off
    When the end-of-discharge voltage is reached, the load output switches off automatically.
    As soon as the restart voltage is reached, 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).
    (factory setting).

The load output can also be switched on or off manually by push button.

Special feature of SCDplus solar controllers: 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 procedure
  • Cut-off voltage
  • Reset voltage
  • Temperature coefficient
  • Load output (reclosing yes/no, timer function and nightlight function)

Parameterization, monitoring and evaluation via PC

+
A connection between the solar controller and PC can be established using the USB interface. 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.
 
Data logging and evaluation with free Windows software

The following parameters are recorded every second:
  • Time (Time)
  • Battery voltage (Voltage)
  • Battery charge current
  • Load current
  • Temperature

More detailed information about the software can be found in the SCplus-/SCDplus-series user manual (see Downloads).

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.

Overcharge protection
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 and reverse polarity by a flat fuse.
