Product Description
2.1 System Introduction
The inverter is a transformerless 3-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 to feed the AC current
into the utility grid.
The intended usage of the inverter is illustrated in the following figure.
