Chapter 2 Overview
2.1 Inverter for grid-tied PV systems
CPS SCA3/4/5KTL series inverter is suitable for use with most household
grid-tied systems. The system is generally made up of PV-panels, a PV-inverter,
an AC-Connection Unit (the connection Interface) and the Grid (Electric Utility)
(see Figure 2-1). When a PV-panel is exposed to sufficient irradiation (sunlight)
and connected to an inverter, it generates DC power. The PV-Inverter converts DC
power to AC power supplied to the Electric Utility via the AC-Connection unit. The
AC power generated is supplied first to local loads. Any excess power is
supplied to your local Electric Utility.
The following figure shows the PV-Inverter in the grid-tied PV System:
