Good luck but I think it's flogging a dead horse.

It depends, however once the supplier importer in AUS went away, none to my knowledge to date has had any warranty dealt with unless it was via the business that installed it. I believe and I could easily be wrong that the importer at the time likely put a 5 year warranty on them but the actual manufacturer in China may well have only put 12months on them. This where the issue become very murky indeed, a manufacturer in another country is not under any obligation of any sort to honour a warranty that was invented in Australia, in fact if a manufacturer/supplier in another country decide not to honour warranty in Australia there is actually nothing we can do about it, unless they have direct local representation. Another country is not bound by ACL at all.
They will likely loose all business here particularly if there are approvals required, but often times they really don't care, even it appears under some other brand name it's not the same product then. Note: KLNE is not sold at all in Australia anymore since the importer went away nor is there any current approval for them either.
The DC operating range is fine 110Vdc to 480Vdc if the array is within that, then it is correct although it preferable under load for it be around 400Vdc ideally, rarely will be, but as close to possible is better. However it has nothing to do with grid disconnect issues it's the nominal grid voltage range that counts, I would assume it's highly unlikely to be outside of those particularly the high end of 280Vac there for it's a good chance without looking inside that grid relay has failed, apparently was a very common issue.
