Steca Tarom
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
for configuring and monitoring the system. An integrated Ah
meter also provides the user with information on the energy
budget of the application.

Steca Power Tarom
2070, 2140, 4055, 4110, 4140
Specially designed for industrial and outdoor applications,
the Steca Power Tarom comes with an IP 65 casing made of
powder-coated steel.
This solar charge controller can be used to control system
sizes of up to 8400 Wp at three voltage levels (12 V, 24 V, 48
V). The Steca Power Tarom is based on the technology of the
Steca Tarom controller. When connected in parallel, several
controllers from this series can be operated via a standard DC
bus in a simple solar home system or a hybrid system. This
allows an output of over 20 kWp to be reached.
