Product Description:

1.  Structure of Solar Photovoltaic Grid-Connected Inverter SG6KTL-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 SG6KTL-EC

• Flexible design due to dual MPPT tracking that is equipped to obtain full nominal power, 3-phase supply

• High energy yield due to maximum efficiency up to 98.1%competitive wholesale price.

Low noise levels and internal consumption due to natural cooling

Integrated theft protectionAC Voltage Range:150V-550Vac

Access to Home WiFi system and enjoy cloud services via smart phones

Integrated power management function, easy to receive the adjustable command from grid

Extensive communication: RS-485, Ethernet, WLAN / WiFi, 4 digital inputs for ripple control receivers

5.  FAQ of Solar Photovoltaic Grid-Connected Inverter SG6KTL-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.
