Product information "Steca Tarom 4545-48"

Steca Tarom 4545-48

  • Large graphical display
  • Extensively programmable
  • Optimal state of charge determination
  • Innovative, comprehensive data logger with energy meter
  • Best choice for system sizes up to 2,700 Wp

The new design for the Steca Tarom sets new standards in this power class. A graphic display informs the user about all important system data and enables configuration and adjustment of the controller to the specific requirements of the individual system.

Numerous clever functions allow the user to adjust the controller to the particular features of the system in question. Thanks to the significantly improved state of charge determination, the system is optimally controlled and the batteries are protected. The Steca Tarom charge controller is the best choice for system sizes of up to 2,700 Wp at three voltage levels (12 V, 24 V, 48 V).

The integrated data logger stores all important system data. Controller data can be read by the minute via a Steca open UART interface. As an option, an external temperature sensor can also be connected.

Two additional switching contacts can be freely configured as a timer, a night light function, to start generators or as surplus management.

Accessory Items

Steca PA TS-S
Steca PA TS-S The Steca PA TS10, Steca PA TSIP10 and Steca PA TS-S external temperature sensors are used for monitoring the battery temperature.All Steca solar charge controllers have an integrated temperature sensor that makes them capable of adjusting the charging strategy to suit the current temperature conditions. The external temperature sensors are only required when the battery must be installed in a different room to the solar charge controller.The Steca PA TS10 and Steca PA TSIP10 are supplied with a plug for connection to the solar charge controller and ring eyelets for connection to the battery screw.The external temperature sensors are suitable for use with Steca PR 10-30, Steca Solarix MPPT, Steca PR 2020 IP, Steca Tarom 4545 and Steca Tarom MPPT 6000 solar charge controllers.

Steca PA CAB2
Steca PA CAB2 Tarcom Steca data cables are used to connect the Steca Tarom and Steca Power Tarom solar charge controllers to a PC via a USB port. This allows direct monitoring of a system without using a data logger. This feature is especially suitable for short-term system monitoring and on-site testing. The most important system information is transferred to the PC in real time and can be conveniently analysed and graphically visualised using the Steca TarCom software.To use this convenient data transfer system a driver and the Steca TarCom software must first be installed on the PC (Download available at„Tarom RJ45 in“ can be selected under options/settings/extra in the Steca TarCom software menu system. The software then directly accesses the data from the Steca Power Tarom solar charge controller and displays this on the PC.
