solar inverter

solar inverter:
1. grid tie inverter with MPPT feature
2.grid tie inverter CE certificate
3.grid tie inverter module


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