Re#42 - you added these remarks by edit:
Most of these inverters have inbuilt RCD protection and they also show error codes if there’s a fault.
Having an external RCD, is probably preventing the inverter from logging any fault.
after I read your first offering which terminated 'Who pays for the installation of this unnecessary and incorrect RCD?'
Spinlondon - what is up with you? If you don't want to read anything from me select 'ignore'. If you do want to read my stuff and comment on it, then please read it more carefully and quote me correctly including any caveats and provisos I include.
