3.CE&ISO
Description,wind solar grid tie inverter 1kw-30kw

It is the core facility of solar power plant and wind turbine power plant. To sure the power plant can run stability, it highly require for the reliability of the grid-connected inverter. For the scurviness environment of the solar and wind turbine, the stability of DC supply is very bad, that more require to consummate the defend function of grid-connected inverter and strong capability to resist all kinds of impact.


Features of Grid tie inverter,

l Controlled by CPU, stability is reliable
l Able to follow up utility grid in milliseconds, complete synchronous with utility grid
l When utility tested by inverter in 3 seconds is normal, the inverter starts to work making sure the inverter won’t be damaged by frequency wave
l It will lock the unit automatically in less than 10ms when utility grid interrupted, over-voltage, or under-voltage
l When wind power over-voltage or solar intensity over strong with DC over voltage, inverter will automatically lock itself. When DC restores inverter will start to work automatically again
l Protection against short-circuit and overload
