Rapid shutdown for rooftop PV systems

Phoenix Contact’s SOLARCHECK RSD improves worker safety

Middletown, Pa. - Phoenix Contact's new SOLARCHECK RSD (Rapid Shutdown) gives solar panel installers an NEC 690.12-compliant solution for the safe, rapid shutdown of rooftop photovoltaic (PV) systems. National Electric Code (NEC) 690.12 dictates that all rooftop solar PV systems must have a rapid shutdown function to protect first responders from electric shock in the event of an emergency.


SOLARCHECK RSD is based on the intelligent analysis of electrical conditions within solar strings. In the event of an emergency, a fault condition within a string, or a manual shutdown for maintenance work, the system automatically switches the PV system into a safe state.

Unlike other solutions on the market today, SOLARCHECK RSD does not require additional communications cables or wireless networks. SOLARCHECK RSD modules are integrated directly onto the panels via a smart cabling system. When the system can be safely restarted, SOLARCHECK RSD switches on automatically, triggered by the startup of the inverter, or optionally, via an enable input.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
