on grid Inverter

1.on grid Inverter According to UL1741,IEEE-2000 standards, 2. has CE certificate, 1KW to 500KW for our on grid inverter

On grid inverter:

  

Features:

1, on grid inverter controlled by CPU, to kep the stability of the unit

2,Inverter grid-connected output, can follow up the utility grid in millisecond, completeness synchronization to the utility grid, on-grid Inverter.

3,when utility grid test by inverter in three seconds is normal, grid-connected inverter start to work. make sure the inverter will not damage by frequence wave.

4,on grid Inverter will lock the unit automatically in less than 10ms when the utility grid interrupted or over-voltage or under-voltage.

5,protection against short-circuit and overload

6,output power invariablenes.(normal DC voltage)

7,when wind power or solar power shortage, DC voltage drop, grid-connected inverter output power will reduce. when Dc over low achieve inverter DC protect point , inverter will auotmatically lock and stop work, when DC restores, it will start the unit automatically again.

8,when wind power over-voltage(such as typhoon), or solar intensity over strong, DC over-voltage, inverter will automatically lock itself. When DC restores, inverter will start to work automatically again.

9, communication ports:RS232, RS485, USB(optional)

10,DC to AC high transfer efficiency up to 90--96%

11, Our products has CE certificate for our on grid inverter.

12, Can design and make as your request..
