Wait for the completion of the pairing (remaining seconds is 0). If pairing fails, an
error is displayed. In this case, repeat the pairing steps, and refer to
Power Optimizer
Troubleshooting
on page 81. If the problem persists, contact SolarEdge Support.
When pairing succeeds, the following message is displayed:
P a i r i n g

Upon pairing completion, the inverter continues with assigning numbers to the
power optimizers and mapping them into strings:
Power optimizer detection
- the power optimizer IDs are detected and each
optimizer is assigned a unique number, which is later used by the inverter for
synchronizing telemetries. This detection is performed while the optimizers are
in safe voltage .
String detection
- During this procedure the logical string of each optimizer is
detected. This detection is performed while some optimizers are set to MaxVout
mode.
The detection and assignment of power optimizers may take up to 2 minutes.
The system startup process begins:
nce the inverter is ON, the power optimizers start producing power and the inverter
starts converting AC.
WARNING!
When you turn ON the inverter ON/OFF switch, the DC cables carry a high
voltage and the power optimizers no longer output a safe 1V output.
When the inverter starts converting power after the initial connection to the AC, the
inverter enters Wakeup mode until its working voltage is reached. This mode is
indicated by the flickering green inverter LED.
While the inverter is in Wakeup mode, it monitors the grid and verifies correct grid
voltage and frequency. The following message is displayed:
W a k i n g U p . . .
R e m a i n i n g : 0 5 1 S e c
The countdown indicates the seconds remaining until entering the Production mode.
This time is in accordance with local regulations and is typically between three to five
minutes.
When countdown is complete, the inverter enters Production mode and produces
power. The steadily lit green inverter LED indicates this mode.
