[QUOTE="Ucatchmydrift, post: 536943, member: 35106"] I havent a clue if im honest, accept for some hybrid inverters like mine have a permanent or temporary neutral to earth bonding inside for whatever reason. maybe in my case a stray dc current comes from the pv down to the earthing rod, and if damp enough, the current reaches the other inverter earthing rod which then goes into the inverter, then through the temporary earth neutral bond when grid power is enabled, which then allows the current down the neutral cable and is picked up by the rcd? Just a thought, but probably wrong as im no electrician or electronics wizz... I guess what i should really say is,, i dont know lol. 😂 [/QUOTE]
