ON/OFF/P Switch:
l
ON (1) - Turning this switch ON (after optimizer pairing) starts the operation of the power
o
optimizers, enables power production and allows the inverter to begin exporting power to the
utility grid
OFF (0) - Turning this switch OFF reduces the power optimizer voltage to a low safety voltage and
o
inhibits exportation of power. When this switch is OFF, the Primary and Secondary Units' control
circuitry remains powered up.
P - Moving and releasing the switch a llows viewing system information via the LEDs and on the
o
SolarEdge SetApp mobile application screen and performing functions:
P Position duration
Switch moved to P for less than
5 seconds, then released.
Switch moved to P for more than
5 seconds, then released.
LEDs
LEDs: three LEDs indicate, by color and state (on/ off/ blinking

information, such as errors or performance indications.
Generally, the main L ED indications are:
Blue ON - the inverter is communicating with the monitoring platform
l
Green ON - the system is producing
l
Green blinking - AC is connected but the system is not producing
l
Red ON - system error
l
1 Blinking = Turns ON and OFF for the same duration
2 Flickering = Turns ON for 100 mS and turns OFF for 5 seconds
