will be testing ac side as mft 's etc are not designed for testing dc and you cant really dead test the strings etc but you can test the cable you made offHi Marc
Yeah that's what we always do but I commissioned a 1.3MW park in Sept and the bank that funded the project for our customer are now requesting the 'Dead' tests as per BS7671?? I supplied the usual tests as in, Voc Isc IR etc. but don't know what he wants.
Any ideas??
you still need ac supply to inverter.Hi shanky
mft, dc tester test each panel before then each string before connection no MFT involved
the dc cables are single core though so as long as not a very long run and there is voltage its fine.Insulation resistance test on dc strings should be recorded on the dc test certificate

(only a pos and neg from panels to inverter on dc side)
