For markets and projects requiring rapid shutdown, SunSniffer and QC Solar combine RSD, full module-level monitoring and patent-pending DiodeVital™ in one factory-integrated junction box. Module manufacturers gain a differentiated rapid-shutdown module with fewer separate system components. Installers no longer need to mount and connect a separate external RSD device at each module. The integrated design reduces hardware and field labor and removes the additional connector pairs that external RSD boxes would introduce.
