Changing the fuse

The solar controller is equipped with an easily accessible plug fuse for the charge and load output.

Attention: Replace the fuse only by a fuse of the same type and rated current!

LCD display (only in SCDplus models)

As soon as the solar controller is connected with the battery, the initialization phase is running for approx. 10 seconds.

The system voltage is identified and taken over by the sensors (Fig. 2).

During this phase the following messages appear in the display:

Fig. 1 Fig. 2 Fig. 3

Attention! Do not push any buttons during this initialization phase!

The display list Fig. 3 displays the following data:

• the current battery voltage (U:)

• the current charging current (C:)

• the current load current (L:)

• the current state of charge (bar graph)

By pressing the  button you switch between the following display messages:

Fig. 4 Fig. 5 Fig. 6

The display lists Fig. 4 - Fig. 6 display the following data:

• the total charge (C:)

• the total energy (E:)

• the current time (Time:)

• the current date (Date:)

• the temperature at the sensor (T:)

• the currently set temperature coefficient (COMP:)

Note:

If the battery cannot be charged due to no or too low solar power, the solar controller switches to standby mode.

Select from the following options to cancel the standby mode:

• automatically by sufficient solar power

• push the 'Load‘ button (14)

• push the ⊳ button (2) (only in SCD models).

Standard device settings (at 12V battery system)

Charging profile/type of rech.battery: SLA (lead-acid battery)

Deep discharge protection: 10.5 V (if the battery falls below a specific charge level, the load output is

disconnected automatically)

Temperature coefficient: 25 mV/K

Load output setting: N/A (manual activation of load output using button 14)

Parametrization and monitoring of the solar controller using Windows software

The free of charge software allows all settings to be made conveniently at the PC: date, time, charge profile, deep discharge protection,

function of load output and temperature coefficient. You can also monitor and record the operating data of your device.

The PC software can be downloaded at the following Internet address. http://www.ivt-hirschau.de/downloads

(The download includes the two files: "SC_series_usb.inf“ (driver) and "SCControl.msi“ (installation data file))

Note:

The solar controller may be parameterized with the PC both with and without battery supply voltage.

When battery voltage is applied, the current operating data will be displayed additionally, which can also be saved on the computer as

*.txt file. (see point "Display operating data“)

When no battery voltage is applied, the device is powered via the USB cable. ("USB powered mode“)
