Product Description
2.1 System Introduction
The inverter is a transformerless 1-phase PV grid-connected inverter. As an integral compo-
nent 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 ac-
cordance 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 dam-
age to the inverter.
• Do not connect any local load between the inverter and the AC circuit breaker.
The inverter applies only to the scenarios described in this manual.
The intended usage of the inverter is illustrated in the following figure.
