Taking the lead on solar-panel safety with a reference design specifically for rapid shutdown


Did you know that TI is one of the first semiconductor companies to offer designs for the rapid shutdown of solar power systems in the event of a fire or electrical hazard?

In 2017, National Electrical Code (NEC) 2017 mandate 690.12 added a new requirement for the safe shutdown of power circuits from photovoltaic modules to power inverters. In the event of a house fire, firefighters need to be able to rapidly de-energize these circuits for everyone’s safety.

The SunSpec Alliance, whose stated objective is to make “plug-and-play communication for distributed energy,” has developed a communication protocol for module-level rapid shutdown – emphasizing low cost and time savings while enhancing the overall health and safety of solar power systems.
