Introduction

With this device you have acquired a solar inverter for the mains connection of photovoltaic sys-
tems. This solar inverter is characterized by its advanced housing design and state-of-the-art radio
frequency technology, which enable the highest levels of efficiency.
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 specifications of DIN VDE 0126-1-1 and compliance with the directives of the
VDEW (Union of German Electrical Power Stations) for parallel operation of power generation
plants on low-voltage grid of regional electrical utility companies. These are declared through the
GS-Innova character and the CE mark (CE Certification - see Appendix).
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.

System

The solar inverter converts direct current from the PV cells into alternating current. This enables you
to feed your self-produced PV energy into the public mains.
Thanks to efficient MPP tracking, maximum capacity utilization of the PV energy plant is ensured
even in case of a misty and clouded over sky.
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 signifi-
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.

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
capable of being called up over the device display. The data interfaces enable the downloading of
data which can be evaluated with the aid of a PC system and thus 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 read-out of the data over the integrated interface and the display is possible only in PV opera-
tion.
