ON/OFF/P Switch
:
Figure 7: ON/OFF/P switch
o
ON (1)
- Turning this switch ON (after optimizer pairing) starts the operation of the power
optimizers, enables power production and allows the inverter to begin exporting power to the
utility grid
o
OFF (0)
- Turning this switch OFF reduces the power optimizer voltage to a low safety voltage and
inhibits exportation of power. When this switch is OFF, the Primary and Secondary Units' control
circuitry remains powered up.
o
P
- Moving and releasing the switch allows viewing system information via the LEDs and on the
SolarEdge SetApp mobile application screen and performing functions:
P Position duration

LEDs
: three LEDs indicate, by color and state (on/ off/ blinking

/ flickering
2
/alternating
3
), different
system information, such as errors or performance indications.
Generally, the main LED indications are:
l
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
1
Blinking = Turns ON and OFF for the same duration
2
Flickering = Turns ON for 100 mS and turns OFF for 5 seconds
3
Alternating = Alternate LEDs flash
