Product Introduction
2.1
Intended Usage
SG36CX-US, SG60CX-US, a transformerless three-phase PV grid-connected inverter, is
an integral component in the PV power system.
The inverter is designed to convert the DC power generated from the PV modules into
grid-compatible AC power and provide it to local loads or export it into the utility grid.
The intended usage of the inverter is illustrated in
Figure 2-1 Inverter application in PV
