Steca Tarom
235, 245, 440
The Steca Tarom is the high-end solar charge controller
optimally designed for demanding telecom applications
and complex off-grid PV hybrid system architectures. A
huge variety of exiting features allows the user to adapt
this controller to the special needs of the specific instal-
lation.
The optimised SOC calculation of Steca is implemented in
the Tarom. It is your best choice for the medium and large
power range (up to 2400 Wp) on three voltage levels (12 V,
24 V, 48 V). Additionally it is possible to connect further
devices like a temperature sensor, a datalogger and a
remote switch to configure and monitor the photovoltaic
system optimally. A built-in Ah counter gives additional
valuable energy balance information to the user.

Steca PowerTarom
2070, 2140, 4055, 4110, 4140
Designed for industrial and outdoor applications, Steca
PowerTarom controllers come in a IP 65 powder painted
steel enclosure for the large power range (up to 8400 Wp)
on three voltage levels (12 V, 24 V, 48 V). Power Tarom
controllers are based on the same technology as the Steca
Tarom controllers. If you connect them in parallel on a
common DC bus power line, several controllers operate
in one single PV or PV hybrid system in the range up to
20 kWp of solar power.

Steca hybrid systems see page 46-47)
