Billy brought up a good point about higher voltage and just going 24v if you want to go over 15V. First, it wasn't until recently that I realized why Unique recommends fused hubs. That should offset the worries about smaller wire and higher voltage, amp load issues, etc. I would love to see the specs on this. Detailed with wiring configurations. Can anyone think of any downsides? The biggest plus I can see is the savings on copper wire. When I install 10 gauge home runs, I feel like I am using 100+ feet of jumper cables. I don't see the big deal in 24v as an electrical potential. Irrigators use it, and they work directly with water.
