When you change your router (e.g., when switching providers) or update your WiFi password, the inverter usually needs to be reconfigured to maintain the connection. This guide explains how to do that.
This step-by-step guide applies only to SolarEdge inverters without a display (using compact technology) that are equipped with WiFi.
