Inverter
StecaGrid 2000+
2,000 W up to
several 10,000 W
Photovoltaic modules generate power from solar energy
in an environmentally-friendly manner. The basis for the
development of the StecaGrid 2000+ inverters was to al-
low this solar energy to be flexibly used in a versatile man-
ner and feed it into the public grid.
The StecaGrid 2000+ is perfectly suited to solar systems
from 2,000 W upwards. Systems between 2,000 W and
6,000 W are implemented with a single device, systems
above 6,000 W can be implemented using several devices
in a master-slave combination.
The StecaGrid 2000+ uses the DualString concept. Every
inverter has two inputs. One module string can be connec-
ted to each input. If necessary both inputs can be con-
nected in parallel. Several combinations of strings and in-
verters are connected to the public grid. The advantage of
such a system is the low sensitivity to negative influences
such as (e.g.) partial shadowing, functional faults, or the
dropout of a string. The use of several decentralized mas-
ter-slave combinations reduces the cost of DC cabling and
minimizes electrical losses.
