Steca Solarix PI
550, 550-L60, 1100, 1100-L60
In developing the Solarix PI sine wave inverter, Steca has
brought about some innovations which are unprecedented in
this form. These are, above all, parallel connection, the novel
operating concept which uses a single rotary switch, direct
communication in order to calculate the state of charge (SOC)
with Steca Tarom and Steca Power Tarom, and the electronic
fuse. Furthermore, our many years of experience have come
into play for deploying these inverters specifically in photo-
voltaic systems. This comes through, for instance, in the way
that a most diverse range of appliances is provided with a low
operating consumption and a stable energy supply.

Steca PL 2085
Solar charging point
The Steca PL 2085 solar charging point is a highly intelligent
maximum power point tracker which is able to charge eight
batteries with different states of charge at the same time.
On the input side, the Steca PL 2085 is fed by a 24 V module
array of up to 800 Wp. Every charge channel operates fully in-
dependently; it is also possible to connect different batteries
with various states of charge. The battery which is connected
first is also the first to be charged. The display can show the
system data for each individual battery. There is a maximum
of 5 A available per charging channel, and a maximum of
four channels can be connected in parallel at once, so that
two batteries with 20 A each can also be charged. Thanks to
the reverse polarity protection, electronic fuse and automatic
detection of a faulty battery, the device is maintenance-free
and user-friendly.
