Hi Corey, Good to hear you’re also using Lumos, I know the rail alignment is what is going to make or break the install, maybe a light weight plywood template is in order! I have requested the slotted rails, the unperforated ones just don’t make sense. The tip on removing part of the rubber bumper to run wiring is a good one, thanks!

Please see attached for an example rooftop installation - these modules definitely end up looking pretty "slick". <https://mailfoogae.appspot.com/t?sender=aY3NoYWxhbnNraUBqb3VsZS1lbmVyZ3kuY29t&type=zerocontent&guid=4ddc6bae-1d89-4a30-9e25-04aa9336e0a1> ᐧ I would echo August's comment about the rail alignment. The module mounting holes allow for a bit of wiggle room, enough to square up any off-kilter modules but not enough to make up for misaligned/non-parallel rails. I would also highly recommend the slotted rails (don't know if the non-slotted rails are even still an option). As you pointed out wire management is simplified with their rails. Wires running perpendicular to the rails can be accommodated by removing one or more of the rubber bumpers to create a gap between the module and rail. We have also used suction cups to assist in lifting these modules to the roof - at 60 pounds apiece they are noticeably heavier that most of other modules we deal with. -- Corey Shalanski Joule Energy New Orleans, LA On Fri, Jun 13, 2014 at 12:38 PM, <re-wrenches-requ...@lists.re-wrenches.org> wrote: Message: 4 Date: Thu, 12 Jun 2014 13:34:44 -0700 From: August Goers <aug...@luminalt.com> To: RE-wrenches <re-wrenches@lists.re-wrenches.org> Subject: Re: [RE-wrenches] Lumos LSX250 modules Message-ID: <0159cb59674b658f52fe85632f56b...@mail.gmail.com> Content-Type: text/plain; charset="utf-8" Hi Chris, We have a complex 86 kW commercial job with Lumos 250s we?ve just kicked off. We have not installed them yet so I can?t offer a whole lot of advice except that the module leads won?t reach each other in landscape orientation so I?d recommend a standard portrait layout. The rails also need to line up perfectly since the modules mount with the four through-holes. We will be landing our panels in about 3 weeks so I should know more then, feel free to ping me if you haven?t made your decision yet. Best, August Luminalt
