2.1 Solar grid-tied power generation system
2.1.1 Application
The photovoltaic grid-tied power generation system consists of solar modules, grid-tied inverter,
metering devices and public grid.
Figure 2.1 Application of iMars 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.
iMars 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 rating.
2.1.2 Supported grid connection structure
iMars 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.
