The new version of the Steca Tarom sets new standards in this power class. A graphical display informs the user of all the important information of the installation, and allows the configuration and adjustment of the regulator to the specific requirements of each installation.

Its many useful features allow the user to adapt the controller to the specific data of his system.

The considerable improvement of the state of charge determining device allows an optimal regulation of the system and the protection of the batteries. The Steca Tarom charge controller is the reference for larger systems with three voltage levels (12 V, 24 V, 48 V).

The integrated data logger stores all the important information of the installation. With the Steca UART open interface, you can access controller data in real time. An external temperature sensor can be optionally installed. Two additional switching contacts can be freely configured as a timer and can be used to manage various functions such as night lighting, generator start-up, or surplus management. A total of six devices can be connected in parallel and communicate via the StecaLink bus.
