1. Structure of Solar Photovoltaic On-Grid Connected Inverter SG20KTL 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
assistance.

5. FAQ of Photovoltaic On-Grid Connected Inverter SG20KTL
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.
