Features
1.Connected by CPU,stablity is reliable
2.Able to follow up utility grid in milliseconds,complete synchronous with utility grid
3.When utility grid tested by inverter in 3 seconds is normal,the inverter starts to work making sure their inverter won't be damaged by frequency wave
4.It will lock the unit automatically in less than 10ms when utility grid interrupted,over-voltage or under-voltage
5.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
6.Protection against short-circuit and overload
