With this device you have acquired an inverter for connection of a photovoltaic system to the grid.

This inverter is characterized by an advanced housing design and state-of-the-art high-frequency

technology, which enable the highest levels of efciency and longest life.

The inverter includes key features and capabilities, such as Unintentional Islanding protection,

LCD, and RS-485 interfaces.

The inverter is usable indoors and outdoors. It meets the requirements of ANSI/NFPA 70, NEC

690.5, UL 1741, IEEE 1547 and IEEE 1547.1 for parallel operation of power generation plants on

low-voltage network of regional electrical utility companies.

The function of the Unintentional Islanding protection (automatic isolation point for in-plant genera-

tion systems) complies with UL 1741 / IEEE 1547 specications.

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 inverter.

The content of renewable energy with respect to overall power consumption worldwide is increas-

ing annually by approximately 25%. The reason for this rise can be primarily attributed to the con-

stantly increasing demand for power, the increasing interest in environmentally friendly technolo-

gies, as well as the increasing costs of non-renewable energy.

By the use of renewable energy sources, the earth‘s atmosphere can be enormously relieved of

increases in CO2 and other harmful gases which result from power generation.

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 efcient MPP tracking, maximum capacity utilization of the solar energy plant is en-

sured even in cases of misty and cloudy skies.

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.

The inverter is transformerless type without galvanic isolation. Therefore, the inverter may only be

operated with ungrounded PV arrays. Furthermore, the PV array must be installed in accordance

with the NEC690.35 (Ungrounded Photovoltaic Power Systems) and the locally valid regulations for

ungrounded PV arrays. Additionally, the PV array (PV modules and cabling) must have protective

insulation and the PV modules used must be suitable for use with this inverter. PV modules with a

high capacity to ground may only be used if the array coupling capacity does not excessed 1,200

nF with 60Hz grid.
