Solar Grid-Tied Power Generation System

Application
The photovoltaic grid-tied power generation system consists of solar modules, grid-tied inverter, metering devices
and public grid.
Figure 1: Application of PSW-G series grid-tied solar inverters
Grid-tied solar inverter is the core of photovoltaic power generation system. The solar energy can be converted into
DC electric energy through solar modules and then be changed into sinusoidal AC energy which has the same
frequency and phase with the public grid by grid-tied solar inverters, and then be fed to the grid.
PSW-G series grid-tied solar inverters are only applied in solar grid-tied power generation system and its DC input are
only composed of crystalline silicon solar modules whose negative and positive poles are not grounded.

The recommended solar modules need to comply with IEC61730 Class A standard.
Supported Grid Connection Structure
PSW-G series grid-tied solar inverters support TN-S, TN-C, TN-C-S , TT and IT grid connection. When applied to the TT
connection, the N-to-PE voltage should be less than 30V.
