Product Description:

1.  Structure of  Photovoltaic Grid-Connected Inverter SG4KTL-S 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, Africa and Europe. Available for hand installation, no need for lifting machinery
