Smart Modules
For Rapid Shutdown

The Power + Solution from SMA offers greater flexibility in solar installations, while driving down system costs and maintenance issues.  Nothing installs faster or easier. 


  • Works/compatible with any solar panel, so installers can use in their existing systems
  • Module-level monitoring and module-level shutdown
  • Faster - Save up to 90 minutes per install compared to other solutions
  • Safer - Reduce roof time by attaching the units to the solar panels on the ground, or even prior to the site visit
  • Easier - Maintenance issues supported by SMA, and repair or replacement is done with simple snap-in cover on the units - no cabling work (electronics are in the removeable cover).  Tool-free installation.
  • The -S version is for Shutdown and Module Level Monitoring - use this when there are no/minimal shading issues
  • The -F version is for Shutdown only - and can only be used with SunSpec compliant inverters ie, Sunny Boy -41 inverters
  • Secure Power Supply NOT compatible with this system
  • NEC 2017 Rapid Shutdown Compliant
  • 25 Year Warranty
