How to test/certify a small 230V generator installation?

Oh ok, So make it into a TNS system

O0ps should have said TNC I suppose?

Not playing games and it is not a quiz - but you are the one doing all the guessing!

FWIW, many people incorrectly assume that connecting an earth rod to a generator-powered installation makes it a TT setup. For anyone who is confused, the rod of a TT installation completes a circuit from the MET back to the earth electrode at the source of supply (substation) via the general mass of earth rather than via a cable. When connecting a generator to a rod, it IS the earth electrode at the source of supply. You would not then generally bang in a second, independent rod to earth the installation, you would run a cable to the generator, making it TN-S.
