   Look at the LED indicator lights on your inverter. Note any specific colors or blinking patterns and refer to your inverter's manual for what they indicate regarding system status or errors.

4. 4

   Visually inspect any external cables connected to your inverter for obvious damage or loose connections.

5. 5

   If the RCD Sensor Error persists after trying these steps, please contact SolarEdge customer support or your certified installer for further assistance. Do not attempt to open the inverter yourself.
