Chapter 2 Overview
2.1 Inverter for Grid-tied PV Systems
3-Phase String Inverters are designed for use with carport, commercial
rooftop, and large-scale PV grid-tied systems. The system is generally made
up of PV modules, DC power distribution equipment, PV inverter and AC power
distribution equipment (Figure 2-1). The inverter converts the DC from PV
modules to AC with the same frequency and phase as the AC grid. All or part
of the AC power is supplied to local loads, and the surplus power is supplied to
the electricity grid.
