Module 45 A, load 45 A, 48 VDC, LCD, IP31, screw terminal 25 mm², programmable, Communication interface (HS400, MPPT6000-M), data logger(SD card)

The new design for the Steca Tarom sets new standards in this class. A graphic display informs the user about important system data and enables configuration and adjustment of the controller to the specific requirements of the individual system. Several intelligent functions allow the user to adjust the controller to the particular features of a system. 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 2.400 Wp at three voltage levels (12 VDC, 24 VDC, 48 VDC). The integrated data logger stores important system data which can be read via an open Steca RS232 interface. As an option, an external temperature sensor can also be connected. Two additional switching contacts can be easily configured as a timer / a night light function, to start generators, or as surplus management. The Steca Tarom works on PWM as a low loss series controller.
