2 Product overview
This chapter mainly introduces the appearance, package accessories, nameplate, technical
parameters of the grid-connected inverter.
2.1 PV grid-connected power generation system
PV grid-connected power generation system is comprised of solar battery component,
grid-connected inverter, power energy gauging device and public grid.
Fig 2.1 Application of PV grid-connected inverter
The PV grid-connected inverter is the core part of solar PV grid-connected power generation system.
The sunlight can be converted through PV panel to DC power, which further converted by grid-tied
inverter to the sine AC current with the same frequency and phase position as the public grid, then
feedback the AC power to the grid.
It is recommended that the PV array to be installed conforms to IEC 61730 class A
standards.
2.1.1 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.
