Save in the right places with Steca Tarom MPPT
With its innovative functions, the Steca Tarom MPPT not only offers
greater efficiency, flexibility and comfort but also helps to avoid cer-
tain unnecessary costs that are incurred during the planning, imple-
mentation and ongoing operation of PV systems.
No need for additional devices!
... due to added flexibility as a result of the wide input
voltage range
The Steca Tarom MPPT can be used with a wide input voltage range,
which allows greater flexibility when selecting modules.
... due to the two separate inputs
Two inputs each with independent MPP tracking in one charge con-
troller provide greater options when it comes to system planning.
With the Steca Tarom MPPT you can not only vary the module types
for each input but the circuits too. Series and parallel circuits can be
combined easily in one system using the universal and flexible Steca
Tarom MPPT. There is no need for an external module circuit box as
all module strings can be connected directly to the charge controller
leading to savings on installation costs.
... due to two maximum power point trackers (MPPT)
The two independent separate maximum power point trackers
enable various module types to be used with just one Steca Tarom
MPPT charge controller. Leftover module stock can also be used in a
system without any problems. Significantly greater options are also
available when upgrading existing systems – without the extra cost
of replacing an existing charge controller. The Steca Tarom MPPT is
particularly suitable for systems where partial shading of the modu-
le array is unavoidable. Due to the two separate MPP trackers, the
charge controller can power different strings with an individually
adjusted MPP. This enables the maximum efficiency to be exploited
for each string enhancing the total output of the system – in spite of
partial shading. The same principle applies also for use on roofs or
areas with various angles of inclination or orientations.
... due to the comprehensive, integrated data logger
The Steca Tarom MPPT is equipped with a unique, comprehensive
data logger, which enables data of the two inputs to be monitored
and saved independently over a period of up to twenty years. The
previous 18 hours can be graphically displayed. Daily, monthly and
annual totals are summarised automatically for an outstanding over-
view of system utilisation at a glance.
No need for additional modules!
... due to the extra high efficiency
The Steca Tarom MPPT is one of the few MPPT charge controllers
that can reliably attain a high and – more importantly – constant ef-
ficiency across all input and output voltage ranges. The high level of
reliability of the MPPT solar charge controller enables you to obtain
even more power from your PV system. For example, significantly
less energy is lost due to unnecessary heat losses. Conversely this
means that, using the same power, as much as an entire module
can be saved during planning if required. Particularly with limited
mounting options or a limited budget this is an indisputable benefit.
Save time and effort during installation!
... due to the easily accessible, easy-to-connect terminals
The extra spacious connection terminal area can be accessed via two
screws on the front of the device meaning installation of cables with
a thickness of up to 35 mm

is simple, fast and secure. An integra-
ted module switch means the Steca Tarom MPPT can be connected
without any voltage connection, sparks or light arcs. Only when the
charge controller is switched on via the menu are the module arrays
connected up. This makes installation child‘s play.
