Product Description:

1. Structure of Photovoltaic Grid-Connected Inverter SG1000TS-MV 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, North America and Europe.

5. FAQ of Photovoltaic Grid-Connected Inverter SG1000TS-MV

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.
