2Kw Inverter tripping RCD when I turn everthing off

[Barnicott-White]

Hello Folks... I wonder if anyone else has had this issue... or an answer... I have a renogy 2000w inverter supplying 240v to my sockets. I also have a shore power connection and a relay that automatically "chooses" which source of power to supply to the sockets. My problem is that when I am using the inverter all is fine... until I turn the inverter off, at which point the in-line RCD ( between the inverter and the relay) trips out. I can re-set it when I turn the inverter on again and everything works fine but I am mystified (and a little anxious) about the tripping... and clues ? Many thanks. Michael

Some RCDs are designed to disconnect when the electricity is turned off, these are known as non-latching or active RCDs. Others are designed to stay connected when the electricity goes off and these are called latching or passive RCDs. Perhaps you have a non-latching RCD which is designed to click off when the inverter is turned off.

I think I love you... I thought it would be something really simple... that I didn't know about. So it is. Thank you dearly, you have saved me a lot of trouble.
