Photovoltaic Hazard Control Application - SolarEdge SE K Series Installation Manual

Photovoltaic Hazard Control Application

SolarEdge commercial optimizers and inverters have been evaluated and listed to UL
3741 and may be used to form a PV hazard control system that utilizes SolarEdges PV
rapid shutdown system to comply with NEC 690.12. Multiple modules may be
connected in series to the optimizer input without exceeding the input voltage rating of
the optimizer (125V dc). The diagram below depicts a typical PV hazard control system
using multiple PV modules in series connected to optimizers. Installation instructions,
warnings and cautions in this installation guide must be followed to comply with Local
codes . The PVRSS shall be installed by qualified persons in accordance with the
installation instructions and all applicable installation codes and standards.
Power optimizer models with input Voltage up to 125Vdc, when used with SolarEdge
three phase inverters and DC safety switches listed and marked with PVRSS, may be
used to form a Listed Photovoltaic Hazard Control System.
NOTE
Power optimizer models compliant with SolarEdge PV Hazard Control System:
UL3741 listed models as noted on power optimizer datasheet.
