I am quite confident this will help, cause the power autages at least in our village can be chaotic, sometimes like a strobe, many short ones and repowering mostly with several tries. I have them installed at the main grid input and at the output of the inverter too, same brand but additional with kilowatthourmeter and leakage breaker, but the delays are just adjustable down to at least one second, even the minimum of 0,1 is printed in the manual : / My Inverter input and output are not connected to the grid and the neutral to earth bonding is still not done, cause my trust into the public grid is equal to zero ; D
Hallo Roland , nach dem AC Ausgang vom Sun habe Ich eine zweipolige 10A Sicherung und gehe danach in die Haus-Steckdose . An welcher Stelle gehört das Relay montiert ? Nach der Sicherung und vor dem Sun ? Oder vor dieser Sicherung ?Grüsse !
Interesting methadology, looking forward to hear the end result.
I hope that the end result is that I do not need to report a defective inverter for many years to come ;)
I always install it on all my Inverter installation
Well that will eliminate the fluctuating grid supply at least in the short cycle, lets hope that was the problem.
great content Roland. I'm not sure about the longevity of those devices though

Good idea. Do the Voltage Protection Relays have a battery or memory to retain parameters if the grid power is disconnected for long time?
i think they do have non-volatile memory (EEprom) . They came with pre-set calibration stored in the memory

hallo Kostas. Vor dem SUN. Sicherung auf der Netzseite. Grüsse
could you post a link of where you bought your device from ? TIA
