When a local wrench did such an install, she grounded every module using Weeb lugs, with # 6 as both the equipment ground and the auxillary ground, She carried the equipment ground down to the inverter and the DC grounding, the auxillary ground to a ground rod.
She said working with the direct attachment took longer than a typical rail mount. ----- Original Message ---- From: Carl Adams <swingjun...@gmail.com> To: RE-wrenches@lists.re-wrenches.org Sent: Mon, January 3, 2011 2:28:59 PM Subject: [RE-wrenches] Standing Seam with direct S-5 attachment & Grounding Wrenches, In reviewing the archive I've seen multiple threads on S5 to module attachment. I did not find any discussions on module grounding on this type of installation or any requirements for grounding the metal roof to which the modules are attached. It has been suggested to me that each roof pan which has a module attached should be grounded (perhaps under the ridge cap). Can anyone offer suggested best practice or requirements regarding this?
