2.1 System Introduction

The inverter is a transformerless 1-phase PV grid-connected inverter. As an integral
component in the PV power system, the inverter is designed to convert the direct
current power generated from the PV modules into grid-compatible AC current and
feeds the AC current to the utility grid.
• The inverter must only be operated with PV strings with class II protection in
accordance with IEC 61730, application class A. It is not allowed for the
positive pole or the negative pole of the PV strings to be grounded. This can
cause damage to the inverter.
• Damages to the product due to a faulty or damaged PV installation are not
covered by warranty.
• Any use other than the one described in this document is not permitted.
The intended usage of the inverter is illustrated in the following figure.
