Hi All,
First time for this so unsure what could be the cause.
CSUN 250 panels - string of 16 connected via 4mm DC cable to Fronius IG TL 4.0 feed to CU via 2.5mm T+E
DC cable run including the array is 22m and the AC run is 12m.
Random tripping of the RCD,
AC circuit is okay continuity and insulation fine, no fault with RCD and Ze on PME is okay. Mains voltage sits at around 245V but have seen some fluctations whilst there which were higher.
DC circuit is okay , insulation okay, individual panels testing and working within tollerances.
Inverter is set to G83 and all UK settings checked and confirmed correct.
What could I be missing?
There dosent seem to be any pattern to the tripping, stays on for several days but will then trip out for hours until the client turns off the array.
Thanks all
Tony
