Steca Tarom
S olar Charge Controllers
235, 245, 440
The Steca Tarom is a solar charge controller specifically desi-
gned for use in telecommunications applications or in hybrid
photovoltaic systems.
Numerous clever functions allow the user to adjust the con-
troller to the particular features of the system in question.
Thanks to the significantly improved state of charge deter-
mination, the system is optimally controlled and 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).
There is the option of connecting additional devices such as
a temperature sensor, a data logger and a remote control [35 A ... 45 A]
for configuring and monitoring the system. An integrated Ah
meter also provides the user with information on the energy
budget of the application.
