Superb, must and should product for house
It is simply superb, Using from almost three years it gives complete protection to house in terms of voltage and current. Good thing is it will auto reset after certain time no need manual intervention after fualt.

When power fails Neutral connection is live only phase disconnects
Only phase isolation is provided, while the neutral remains live at all times. This is not safe for both equipment and human safety. In case of incorrect wiring, voltage may also be present on the neutral. In houses where an inverter is installed, during a power failure, current can flow back through the neutral to the electricity line. This creates a dangerous situation, as a person working on the line may receive an electric shock.

Received a faulty item and cannot be returned since return window is closed
Don’t buy this product since I received a faulty one which does work. I am not able to return this item since return window is closed. They don’t have any quality control, otherwise they wouldn’t send me such a faulty one.

Calibration is not perfect
