Wait until completion of the coupling (seconds remaining is 0). If the pairing fails,
error message is displayed. In this case, repeat the coupling steps. If the problem persists, contact SolarEdge
support. When the pairing is successful, the following message appears:

•
To the extent that the UPS is on, the power optimizers start producing power and the inverter starts converting
AC
WARNING !
When the ON / OFF switch of the inverter turned on, the DC cables carry a high voltage and power optimizers have no safe 1V
output.
•
If the inverter starts the energy conversion after the initial connection to the AC, the inverter enters the
standby mode until the working voltage is reached. This is indicated by the flashing green LED on the
inverter.
•
When the inverter is in standby mode, it monitors the network and checks the correct voltage and frequency of the
network. The following message appears:
R awakening. . . R Estant: 0 5 1 S ec
The countdown indicates the seconds remaining until the device comes into production mode. This time is
consistent with local regulations and generally it is three to five minutes.
•
When the countdown is completed, the UPS switches to Production mode and produces power. This is
indicated by the steady light of the green LED on the inverter.
Step 3 Check the health
Once the reactivation time completed, a status screen similar to the following screen appears on the LCD panel of the
UPS:

P_OK: XXX / YYY:
A connection is established with power optimizers and at least one power optimizer sends
monitoring data. Optimizers send telemetry at a frequency of 10 minutes. Initially after the coupling, both XXX
and YYY values display 000 and increases when coupled power optimizers are reported.
NOTE :
Sometimes it takes up to 20 minutes for all power optimizers to transmit their telemetry and be counted on the LCD screen.
