1.3 LED Indicator Lights
The Solis S3-WIFI-ST data logger has three LED indicator lights. These lights depict
the status of the logger. There are three lights: NET, COM, and PWR. The chart below
explains what the lights mean when they are flashing, solid, or off. lf the LED lights are
all off when the inverter is getting proper voltages, please contact Solis Support.

Normal Operation:
Once the logger has been configured
properly, all three LED indicator lights should be solid.
Every Five Minutes:
The logger will transmit a data package to SolisCloud.
When this happens, the COM light will flash for a few
seconds. This is normal behavior and should not cause
any concern.
