SolarEdge Safety & Monitoring Interface

Safe DC

The SolarEdge Safety & Monitoring Interface provides the benefits of module-level safety and monitoring for systems using a non-SolarEdge inverters.

The interface unit collects module performance data measured by each power optimizer and transmits the data to the SolarEdge monitoring server to allow for module-level and system-wide monitoring. It activates the SafeDC™ feature of the power optimizers, which automatically shuts down module DC voltage during AC power shutdown, for safe installation, maintenance and firefighting. This provides multiple advantages when adding SolarEdge power optimizers to existing installations. The Safety and Monitoring Interface can be added at any stage to an existing installation that has SolarEdge power optimizers.

The Safety and Monitoring Interface is compatible with a wide range of non-SolarEdge inverters, certified for outdoor installation and is easy to install.

Module-level monitoring
Module safety DC voltage for installer, maintenance and firefighter safety
Mobile and web-based module performance monitoring
Communication via RS232, RS485 or Ethernet
IP65/NEMA 4 - Outdoor installation

Monitoring Platform

Web-Based SolarEdge Monitoring Portal

The web-based SolarEdge monitoring portal provides enhanced PV performance monitoring and yield assurance through immediate fault detection and alerts at module level, string level and system level.

No hardware or wiring is required to transmit data from the power optimizers to the inverter: the monitoring sensors and transmitters are built into the SolarEdge power optimizer and solar inverter, and measurement data is transmitted over the regular power lines.
