Mac, Do you mean to ask for a way to shut down the Sunny Boys connected to the Multicluster box? Sunny Islands are not applicable to the rapid shutdown requirements. They are not PV.

From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Mac Lewis Sent: Friday, July 17, 2015 10:27 AM To: RE-wrenches Subject: [RE-wrenches] Rapid Shutdown Hi Wrenches, I am working on a rapid shutdown design with an SMA multi-cluster box with 6 x 6048 Sunny Island Inverters, 2 per phase. I will be utilizing a Midnite system for some roof top combiners. Is there a way to shutdown the Sunny Islands via communication from the Midnite rapid shut down box? Or do I need to do shunt-trip breakering? Thanks -- Mac Lewis "Yo solo sé que no sé nada." -Sócrates
