Operation and installation manual SOLIVIA 2.5 EU G3
3 Introduction
With this device you have acquired a solar inverter for connection of photovoltaic systems to the
grid. This European solar inverter can be used in and is approved for the following countries:
Belgium, Czech Republic, France, Germany, Greece, Italy, Portugal, Spain and United Kingdom.
The solar inverter is characterized by its advanced housing design and state-of-the-art high-fre-
quency technology, which enable the highest levels of efciency.
The solar inverter includes monitoring units, such as anti-islanding protection. The function of the
anti-islanding protection (automatic isolation point for in-plant generation systems) stipulates com-
pliance with the specications of DIN VDE 0126-1-1, EN 50438, ENEL G.L., RD 1663, RD 661, UTE
15712-1, Synergrid C10/11 and G83/1-1, and compliance with the directives for parallel operation
of power generation plants on low-voltage grid of your local utility companies. These are declared
by certicates (see § 13).
The inverter is usable indoors and outdoors (IP65).
In the following technical description, the precise functions are explained to the installer, as well
as the user, which are required for the installation, operational start-up and handling of the solar
inverter.
4 System
The solar inverter converts direct current from the solar cells into alternating current. This enables
you to feed your self-produced solar energy into the public grid.
Thanks to efcient MPP tracking, maximum capacity utilization of the solar energy plant is ensured
even in the case of cloudy sky conditions.
The string concept means that PV modules are always connected in series (in a string) and/or that
strings with the same voltage are connected in parallel to the solar inverter with the aim of signi-
cantly reducing the photovoltaic system’s cabling requirements.
The fact that the modules are connected in strings also means that the photovoltaic system can be
perfectly matched to the solar inverter’s input voltage range.
4.1 Data evaluation and communication
The integrated data display, processing and communication of the device enables easy operation of
the solar inverter. Monitoring of the operational status and signaling of operational failures are ca-
pable of being called up over the device display. The data interface enables the downloading of data
which can be evaluated with a PC system and guarantees continuous recording of operating data.
The best way of accessing this functionality is via the available accessories (e.g. WEB´log); com-
prehensive and seamless solar inverter monitoring is ensured.
The data read-out over the integrated interface and the display is possible only in solar operation.
