[RE-wrenches] Stainless Steel Cable Ties
Wrenches, I searched the archives, but came up with nothing on this. I have found a good supplier for reasonably priced stainless steel cable ties and have been using them in place of black nylon cable ties for supporting cables, PV wires and micro-inverter wires to the mounting rails and such. I feel better knowing the wires under the array are supported this way rather than with plastic/nylon cable ties, for which I tried but cannot get a manufacturer to guarantee will last 20+yrs. A colleague is questioning this method (SS ties) with the concern that over time the (albeit small) movement in the wires and/or expansion/contraction of the rails could result in the stainless steel cable ties cutting thru the wire's insulation and then.. I have heard this concern before from others as well. The way I see it is that the very popular stainless steel "S" cable clips that hold wires to module frames have comparable equal sharp edges as well and would pose the same risk, but there doesn't seem to be any concern there. I am wondering who else is using SS ties in place of nylon ones, and if you are taking additional steps to protect the wire's insulation from the SS ties? Common sense abides, meaning don't wrap a wire around the SS ties so that the wire has tension on the sharp edge of the tie. Flat edge contact with the wire only, the same way that you wouldn't run a wire across/around a sharp cut edge of a rail or anything else.

Re: [RE-wrenches] Solarworld SW 165/175 needed
HA, HA, HA. you must be joking Sorry Bruce, just we've been in this situation many times over the past few years; It's been a real pain. I actually think the best thing might be to pull some 175s out of service on a system upgrade for one customer in order to use them for other customers' systems. We found a few modules that were close dimensionally and performance wise, but they were not exact. (Conergy 180 worked, but was off by a couple of inches on the length as I recall) R.Ray Walters CTO, Solarray, Inc Nabcep Certified PV Installer, Licensed Master Electrician Solar Design Engineer 303 505-8760 On 4/24/2013 3:52 PM, Bruce wrote: Does anyone know where I might find a Solarworld 165 or 175 mono module?
