Product Description

Product Description

Module-Level Rapid Shutdown is a safety feature for photovoltaic (PV) systems that quickly de-energizes the DC conductors of individual solar panels in the event of an emergency, such as a fire or utility grid outage. This helps to protect firefighters and other first responders from electrical hazards while working on or near a solar array.

How MLRSD Works

MLRSD systems typically consist of small electronic devices, called rapid shutdown devices (RSDs), that are installed on the back of each solar panel. These RSDs are connected to the panel's DC output and are controlled by a central module or inverter. In the event of an emergency, the RSDs can be activated to quickly reduce the voltage on the panel's DC conductors to a safe level, typically around 30 volts. This can be done within 10 seconds or less.

• Installation: Mounted on the back of each solar panel.
• Function: Reduce the DC voltage on the panel itself to safe levels (around 30 volts) within a short timeframe (typically 10 seconds) after activation.
• Benefits:
  • Offers greater safety for firefighters and solar technicians working near the panels.
  • May comply with regulations like the National Electrical Code (NEC) requiring rapid shutdown for specific areas of DC conductors.
