Chapter 1: Introduction to the SolarEdge
Safety and Monitoring Interface
Overview
When connecting SolarEdge power optimizers to a non-SolarEdge inverter, the SolarEdge Safety and
Monitoring Interface (SMI) device enables the following features:
Safety functions of the optimizers.
Communication of the module-level data sent from the optimizers to the SolarEdge monitoring
portal.
The SMI is installed between the SolarEdge power optimizers and a non-SolarEdge inverter. The SMI is
compatible with any on-grid inverter. For some inverters, it may also serve as the inverter data logger,
which monitors power optimizers and inverter data in a single location – the SolarEdge monitoring portal
*
.
The SMI supports the optimizer SafeDC™ feature. The SafeDC™ mechanism automatically shuts down
module voltage whenever the grid power is shut down, thus providing greater safety during installation,
maintenance and firefighting.
