Inverter Status LEDs
The Inverter is equipped with a status LED on the front panel, and a Network status LED on the communications module. The
optional EMS Ethernet module also has an Ethernet status LED. The table below lists LED indications, probable cause, and
rectification steps.

11.5.2 INVERTER STATUS LED (MULTIPLE-INVERTER INSTALLATIONS)
Your system may include multiple SI series inverters. The inverters are interlocked to ensure a fault on any inverter causes the
other inverters to shut down until the triggering fault is rectified, or the faulting inverter is completely powered off. Outside of
a fault event, each inverter will run independently.

Unknown fault on one
inverter and grid-disconnect
on other inverters
Restart the faulting inverter. If it
restarts the other inverters will
automatically reconnect to the grid.
If the faulting inverter does not
restart, completely isolate the
inverter (PV ARRAY DC isolator OFF
and Grid AC isolator OFF). The other
inverters will reconnect to the grid.
