Grid Connected Inverter

Description of Grid Connected Inverter

Grid Connected Inverter is a special type of inverter that converts direct current into alternating current and feeds it into an existing electrical grid. Thus they form the heart of every solar energy system.

In the development of Inverters, MRE has thought out new technologies and searched for innovative solutions which finally brought our customers efficient and reliable gird connected inverter.

Grid Connected Inverter, as a high qualityinverter, is provided by China professional inverters manufacturer---Shenzhen Modern Renewable Energy Limited whose other products like off-grid inverter still be sold well among the whole world.

Features of Grid Connected Inverter

→used the up to the minute CPU for Eupec,the efficiency of the systems will be high,with LCD display:input power,output power;input voltage,output voltage, input current ,output current; frequency,temperature and so on.

→base on all numeral controller technology,have many kinds of intelligentize controller function.

→the system used advanced form technology,reduce city power current's aberrance.

→have perfect protect function,the highest dependability of the system.

→have MPPT function,no matter how many power from wind or solar,this grid connected inverter will get the power to the grid .

→low voltage design,can working for wind and solar hybird system.

→ for transformer technique,make100% copper transformers materials

→ electromagnetic compatibility: EN50081,part1 EN50082,part1

→Grid disturbance: EN61000-3-2

→Grid text : DIN VDE 126

→Protection degree:IP 20 or IP65(outdoor)

→Self comsumption at night:0W

Start way: As long as wind turbines or solar panels from the issue of an electric, grid connected inverter can automatically get the power to the grid without needing to manually boot.

This inverter is also directed with a load, working like off grid inverter .
