Rapid Shutdown Device

Patented Rapid Shutdown Device Manufacturer

For solar rooftop and building fire safety, our string level and module level rapid shutdown devices control the panels’ voltage down to a certain safe level at microsecond. Prevent accidents and improve the safety of solar power system.

The rapid shutdown solutions are designed according to CE, UL standard and NEC2020 requirements. Proudly as a member of Sunspec alliance,  we develop PLC communication RSDs for wider compliance with multiple string inverters. Check out our products today!

How we satisfy NEC requirements for RSDs

The 2017 National Electrical Code (NEC) Section 690.12 requires the module-level rapid shutdown of solar systems, all conductors within an array’s 1-ft boundary have to be reduced to 80V or less within 30 seconds of rapid shutdown initiation.


The module-level rapid shutdown solutions we are offering allow all types of solar modules can be communication cable version and Sunspec version:


*24VDC communication cable + emergency button switch RSD initiation

*PLC communication + RSD transmitter


Panels connected with BENY Electric RSDs will be reduced to 0V in microseconds, and the AC powered emergency switch or the RSD transmitter completes the RSD solution meets the NEC rapid shutdown solution.
