Steca Tarom 245, 445

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 2400 Wp at three voltage levels (12 V, 24 V, 48 V).

The integrated data logger stores all 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 freely configured as a timer, a night light function, to start generators or as surplus management.
