Steca Tarom

235, 245, 440


The Steca Tarom is a solar charge controller specially designed for use in telecommunications applications or in photovoltaic hybrid systems.

A wide range of interesting functions allows users to adapt the controller to the specific conditions of their systems. Based on the significantly improved state of charge calculation, the system is ideally regulated and the batteries are protected. The Steca Tarom charge controller is the best choice for system sizes up to 2,400 Wp at three voltage levels (12 V, 24 V, 48 V).

Optionally, it is possible to connect additional devices such as a temperature sensor, a data logger and a remote control for configuring and monitoring the system. An integrated Ah counter also provides the user with information about the energy balance of the application.
