1. Structure of Solar Photovoltaic Grid-Connected Inverter SG3KTL-EC Description
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 the Solar Photovoltaic Grid-Connected Inverter SG3KTL-EC

5. FAQ of Solar Photovoltaic Grid-Connected Inverter SG3KTL-EC
Q1. What is the difference between inverter and solar inverter?
A1. Inverter only has AC inpput, but solar inverter both connect to AC input and solar panel, it saves more power.
Q2. What is the difference between MPPT&PWM?
A2. MPPT has higher efficiency, it can track the max power point and won't waste energy.
