THE BIG INVERTER FAMILY
THE RIGHT ONE TO SUIT ALL REQUIREMENTS
The most important criteria for selecting a
photovoltaic installation are reliability, longevity
and cost effectiveness. The inverter - the heart of
the photovoltaic installation - plays an important
role here. It is the link between the PV modules
and the public electricity grid. By means of the
inverter, the DC voltage generated in the modules
is converted into the AC voltage conforming to
the grid.

INDIVIDUAL MPP TRACKING
Every DC performance unit is assigned an individual
MPP-Tracker. Strings with different parameters
can be connected to one inverter and an optimal
yield is nevertheless guaranteed. For example:
· installations with partial shading
· East/West installations
· Different number of modules in each string
· Different types of modules in each string
POWERCONCEPT ®
The inverters from Powerstocc 3000 onward have
several DC performance units. In order to make
better use of diffuse radiation, the strings of the
inverter are interconnected as an internal
master/slave circuit with major advantages.
The master task is taken over by different operative
units depending on the operating hours.
MODULAR DESIGN
Innovation means developing a manageable
service concept. With consistent modular design,
individual units can simply be replaced. The
forward-looking architecture of the Powerstocc
inverter features the cutting edge of the most
modern developments in performance electronics.
CAN-BUS
The reliable and industrially proven data transfer
protocol takes over the internal control of the
Powerstocc inverters. CAN-bus technology has
been applied countless times in the automotive
industry, among other areas, and stands for
security at the uppermost level. With its data
communications galvanically isolated from its
performance section, inverter »downtimes« are as
good as impossible.
