Friends:
I am working on an off-grid system that includes a Sunny Island Mini-grid and some Tristar 600 volt charge controllers. Everything is interconnected in 8 by 8 gutters around three sides of an equipment room. Wiring includes 48 volt DC, 120/208 VAC, 400 plus volt PV feeders and CAT 5. All of this wiring can coexist as THWN and MTW rated at 600 Volts, except the CAT5. We created a partition system by running ½ EMT and NMLT inside the gutter to carry the CAT5, and the system works by maintaining separation and preserving the aesthetic of the equipment room. It is a bit of a pain in the butt, however, to run the EMT/NMLT in the gutter. I got to thinking there has to be a better way. I contacted PV Cables, Inc, and they found a CAT5e that has a jacket rating of 600 VDC. This is the answer to my dilemma on this and on some non-PV industrial jobs. The only down side is the wire is available in 1000 foot rolls at about $800.00 per roll. I also worry about if the wire will accept standard RJ45 connectors. I have ordered a sample. I thought you all should know about this, which is why I am writing. That, and Id like to know if anyone wants to split the cost of a roll. I need about 200 feet. Please contact me off-line.
