Installing SMA’s Rapid Shutdown System: Tech Tip Video


Check out our latest Tech Tip to learn how to properly install SMA’s Rapid Shutdown System.

Why choose SMA’s Rapid Shutdown System? First of all, it’s the most cost-effective way to comply with 2014 NEC 690.12 for states that have adopted 2014 NEC or will be adopting it soon. It will also ensure compliance in those states that have adopted 2017 NEC, until the 2019 80-volt limit goes into effect.

Another major reason to select SMA’s Rapid Shutdown System is that it is compatible with our Secure Power Supply functionality for residential string inverters in case of grid outages – whereas other rapid shutdown systems would eliminate such functionality.

Finally, our Rapid Shutdown System is fast to install. It also fits underneath a module, so you won’t need to extend racking to accommodate it.
