I indicated that the PV source conductors (or inverter output conductors in the case of microinverters) would simply be reconnected in a roof mounted junction box. This never rose to the level of requiring updating electrical wiring to current codes with respect to rapid shutdown or otherwise. We always made sure labels were legible and did any minor electrical cleanup, but I would not even provide a detailed electrical plan with our applications.</div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><br>Jason Szumlanski<div><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">Principal Solar Designer | Florida Solar Design Group</span><br style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px"><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">NABCEP Certified Solar Professional (PVIP)</span><br style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px"><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">Florida State Certified Solar Contractor CVC56956</span></div><div><font color="#333333" face="Roboto, RobotoDraft, Helvetica, Arial, sans-serif">Florida Certified Electrical Contractor EC13013208</font></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Mar 20, 2024 at 9:35 PM Howie Michaelson via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" rel="noreferrer noreferrer" target="_blank">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Hi all, <div dir="auto">I have a potential job reinstalling an 11 year old 4.4kW roof mounted net metered array, feeding a PVI 4kW inverter. The array was pulled down by a reputable company last fall, with the intention of remounting it after the asphalt shingle roof was reroofed. From a distance, it appears that it was carefully removed and all parts and pieces were saved. Unfortunately the company's principle died in the interim and the company folded. I'm trying to determine if this scenario is grandfathered code wise, since it predates RSD. If not, I'm not sure it is worth retrofitting it with add on Tigo or APSMART equipment as opposed to replacing the whole system. In any case, before we explore the options, I'm trying to determine if putting it back up without RSD is (1) code compliant and (2) reasonable. </div><div dir="auto">Thanks for any insight, </div><div dir="auto">Howie Michaelson</div><div dir="auto">Sun Catcher </div></div>
