Neither. You need to send the DNO the G83 test certificate for the inverter (downloadable from SMA's website or from your supplier) along with your DC & AC test certs, Appendix 3 commissioning form, schematic etc.....
We put all the paperwork that comes with the inverter in the customer's handover pack.
