When a fire occurs at a property with a solar array, firefighters need a safe way to cut the power. However, simply turning off the main inverter doesn&#8217;t stop solar panels from generating dangerous high-voltage DC electricity when the sun is shining.<\/span><\/p>\n<p class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">Rapid shutdown regulations were introduced to solve this by actively reducing the voltage within the solar array to safe levels within seconds.

If you are not using a strictly certified UL 3741 PV Hazard Control System (which dictates specific inverters and racking), you are still required to use module-level rapid shutdown devices to meet the 80V inside-the-boundary limitation.<\/span><\/p>\n<p class=\"ng-star-inserted\"><strong><span class=\"ng-star-inserted\">Does NEC 2023 change the rapid shutdown voltage limits?<\/span><\/strong><\/p>\n<p class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">No. The core voltage limits established in previous versions remain the same: voltage must drop below 30V outside the array boundary and below 80V inside the boundary within 30 seconds of initiation. NEC 2023 simply broadens the acceptable methods (like UL 3741) to achieve firefighter safety.<\/span><\/p>\n<p class=\"ng-star-inserted\"><strong><span class=\"ng-star-inserted\">Can YRO rapid shutdown devices be used in NEC 2023 compliant installations?<\/span><\/strong><\/p>\n<p class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">Absolutely. As a highly reliable module-level rapid shutdown solution, YRO devices guarantee that the voltage drops to safe levels, making them fully compliant with NEC 690.12 regulations regardless of whether your local AHJ uses the 2017, 2020, or 2023 standards.<\/span><\/p>\n<h2 class=\"ng-star-inserted\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><span class=\"ng-star-inserted\">\u0e1a\u0e17\u0e2a\u0e23\u0e38\u0e1b<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"ng-star-inserted\"><span class=\"ng-star-inserted\">As solar safety standards like NEC 690.12 continue to evolve from 2020 to 2023, the ultimate goal remains the same: protecting the lives of first responders.
