The new design for the Steca Tarom sets new standards in this power class. The graphic display informs the user of all important system data. The data are saved by the integrated data logger.

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 ideal choice for larger systems at three voltage levels (12 V, 24 V, 48 V).

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