ON/OFF/P Switch:
Figure 11: ON/OFF/P switch
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.
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.
P - Moving and releasing the switch allows viewing system information
via the LEDs and on the SolarEdgeSetApp mobile application screen and
performing functions:
