Older solar installations pre-dating NEC 2014 regulations do not require a rapid shutdown system to be fitted. Neither does a ground mount system, new or old. What is solar rapid shutdown, and how does it work? Solar rapid shutdown refers to the ability, mandated by regulation, to easily shut down a solar panel system in case of an emergency.
Properly shutting down a solar PV system is a common concern among users. Within the entire system, the AC side can be disconnected via the NFB (no-fuse breaker) on the AC distribution panel.
Where a photovoltaic (PV) system cannot be shut down in a fire situation, this can make fighting fires more complex with the possibility of the risks of shock in particular being extremely severe. Figures have shown that there has been a higher number of incidents involving solar panels & now we need a coherent framework to do it safely.
Voltage drop in long-wire run wiring in solar PV systems is one of these important aspects of the system and can affect system performance in a huge way. To reduce voltage drop and still comply with NEC Rapid Shutdown requirements, installers can either use larger wire or change the configuration to shorten runs.
