🔥 Solar Safety Starts with Rapid Shutdown
In modern rooftop solar system installations, safety and code compliance are just as important as energy output. One of the most important code requirements today is Rapid Shutdown (RSD), especially for solar projects in the U.S.
The Envy Inverter helps solar installers and homeowners meet NEC 690.12 requirements easily, thanks to its integrated Rapid Shutdown transmitter. Built with safety in mind, it reduces risk, streamlines installation, and eliminates the need for external RSD devices.

⚡ What Is Rapid Shutdown (RSD)?
Rapid Shutdown is a fire safety regulation defined by the National Electrical Code (NEC) 690.12. It requires that rooftop solar panels reduce DC voltage to below 30 volts within 30 seconds after the system shuts down or in the event of an emergency.
This safety feature is essential for:
• 🚒 Protecting firefighters and first responders
• 🧰 Making system maintenance and servicing safer
• 📋 Ensuring code-compliant solar installations
• 🔌 Passing local inspection and utility interconnection approvals
In short, NEC-compliant rapid shutdown isn't just good practice—it’s a legal requirement in many jurisdictions.

🧠 Built-In Safety: Envy Inverter Includes RSD Transmitter
Unlike typical inverters that require external RSD transmitters, the Envy Inverter comes with a pre-installed APsmart Rapid Shutdown Transmitter located behind the communication board.
This integrated RSD solution removes complexity from the installation process and improves long-term reliability.
Key Benefits:
• ✅ Factory-integrated RSD transmitter—no extra wiring
• 🔌 Compatible with APsmart RSD-S and RSD-D receivers
• 🔋 Powered by internal 12V/1A supply
• 🌐 Supports SunSpec RSD signaling protocol for broad compatibility

🛑 How It Works: RSD in Action
When the Envy Inverter is powered on, its built-in transmitter continuously signals APsmart receivers, keeping the system active. If an emergency occurs or the RSD STOP button is pressed, the signal halts, triggering receivers to shut down the connected PV modules.
Within 30 seconds, the system voltage drops below 30V, ensuring safety for emergency response teams and technicians.
Emergency Setup Tips:
• Install a Normally Closed (NC) STOP button in an accessible area
• For multi-inverter systems, wire STOP buttons in series
