2 Overview
This chapter mainly describes product introduction, components and working principle, etc.
2.1 Product Intro
The inverter converts the DC energy from PV array into AC energy and then feedbacks to power grid,
which is suitable for the commercial roof grid-tied system and large power station grid-tied system.
The PV grid-tiedgeneration system consists of PV array, PV grid-tied inverter, transformer(According
to practical application) and power distribution system, as shownFigure2-1.
