All the European spec inverters I have used would shut down at 600V so that's not a great idea. On systems with long runs, we use a fused switched combiner and run 1KV #6 for the home runs. But that's for very long runs. You can put a lot of power over a #10 PV Wire at 800V working voltage. On We

Hi Dave, We've run all the way home with 1000 V PV wire and only made splices with Amphenol MC4-type 1000 V connectors. Going forward, we are going to strive to put inverters on the roof to minimize the expense of dealing with the 1000 V runs. Another interesting idea is to use the 1000 V inverter
