HI Chris,
According to the spec sheet, the Sunny Tripower is rated MPPT from 300 V to 800 V with a min MPPT tracking capability down to 150 V. It seems like going below 600 V would work fine witch that particular inverter. I haven't checked the specs on all the others.

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.

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 inverters but just run them below 600 V and use standard 600 V wiring products. On a separate note, we have a lot of 208 VAC applications in the Bay Area and all these new neat TL inverters only run at 480 V. Someone from SMA recently pointed out that we can source 480 to 208 V transformers for a reasonable cost - we might look into that as well.

If not-- what splices have you found (aside from MC4s and similar) that are listed for 1000V? And when transitioning from PV WIRE to a cheaper conductor, what 1000V options exist beyond USE-2? Thanks!
