SMA gave a webinar on this topic recently and from it, they gave a number of resources for 1000V rated components. >From their list: PV Cable - Allied Wire and Cable, General Cable, Southwire, Shoals DC combiners - Amtec Solar, Solar BOS, Tealsolar, Sunlink, Shoals DC disconnects - SMA, Bentek,

Re-Wrenches I have done numerous Mountaintop telecommunication PV systems, and they use outdoor rated cabling in cable trays extensively on their towers into their control rooms. If it can survive the UV, snow wind and ice rime buildup there I am sure it can handle many of the roof top locations

Hi Chris, Thanks for a glimpse of how our German brethren handle PV design & installation. After all, who has more experience with design, execution, and funding than the Germans? There remains an arrogance that the US has a lock on how best to do any number of things. Hopefully, this antiqu
