Steca Power Tarom
2070, 2140, 4055, 4110, 4140
Designed for industrial and outdoor applications, Steca Power
Tarom 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 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 installation.
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). Addi-
tionally 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. An in built Ah counter gives ad-
ditional valuable energy balance information to the user.

Steca Solsum
5.0c, 6.6c, 8.0c, 8.8c, 10.10c
One of Stecas bestsellers are the photovoltaic controllers of the
Solsum C series which are used in small solar home systems with a
5 to 10 Amp solar charging and load current capacity (up to 240
Wp). The Solsum C series was launched in 2004 as a redesign of
the Solsum X series. The C series advantages are large connection
terminals, fully covered PCB and a easy to understand display. The
electronic board uses automized through hole technology for easy
local maintenance.
