E-Star - Model HERF Series - Array Level Rapid Shutdown System - Brochure

HERF Series Array Level Rapid Shutdown has the functions of automatic power off and reclosing. On the basis of meeting the requirements of fast shutdown function required by NEC2014 690.12, it can ensure the power generation of photovoltaic power generation system to the greatest extent and improve the power generation rate. When the mains power is cut off, the HERF series array level rapid shutdown will automatically cut off the photovoltaic DC power, so that the circuit of the photovoltaic power generation system 10 feet (i.e. 3 meters) away from the photovoltaic array will fall below 30V in 10 seconds; When the mains power is restored to normal, the cascade Rapid shutdown of HERF series group will automatically reclose to restore the power generation of photovoltaic system.
