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
power system".
FFiigguurree 22--11 Inverter application in PV power system
Inverter cannot connect the PV strings whose positive and negative terminals
need to be grounded.
Do not connect any local load between the inverter and the AC circuit breaker.
