Product Description:

1. Structure of Photovoltaic Inverter 50KW Off Grid Three Phase

A solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a

 utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is

a critical 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.


2. Main Features of Photovoltaic Inverter 50KW Off Grid Three Phase

• using IGBT from Mitsubishi company as the power components
