F23 error without solar panels and with RCD in grid feed.
3.6kW inverter with two BYD battery packs connected and NO SOLAR PANELS. System has been online for months. Recently F23 error has come up.
If fault goes away will it reset automatically or do I need to try a reset somehow?
I have a RCD in the feed circuit to the inverter and it is not tripping. Does that help clue in to the problem?

Error Description:
F23
AC leakage current is trans
over current
Leakage current fault
1.Check the PV module and inverter cables.
2.You may have a faulty PV panel (earth short)
3.Restart inverter
I assume you have a separate isolator or fuse for each PV string. Turn each on of in turn. This will help isolate which string has a earth leakage fault.
