1. Structure of Photovoltaic Grid-Connected Inverter SG100K3 Description
A solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into
autility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.
It is acritical BOS–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar inverters have
special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
Suitable for 50Hz/60Hz grid, could be used in Asia, Australia and Europe.
