Step 2, Pairing Power Optimizers To The Inverter - SolarEdge 3000A-US Installation Manual

Step 2, Pairing Power Optimizers to the Inverter

Once all connections are made, all the power optimizers must be logically paired to their inverter. The
power optimizers do not start producing power until they are paired with an inverter. This step describes
how to assign each inverter to the power optimizers from which it will produce power. Perform this step
when the modules are exposed to sunlight.
1
Verify that the inverter ON/OFF switch is OFF.

Press and hold down the inverter LCD light button for about 10 seconds. The following message is
displayed:

3
Turn the inverter ON within 5 seconds. If you wait longer than 5 seconds the inverter exits the
pairing mode.
The following message is displayed indicating that the inverter is performing the pairing.

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.
When pairing succeeds, the following message is displayed:

The system startup process begins:

Since the inverter is ON, the power optimizers start producing power and the inverter starts
converting AC.
WARNING!
After 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.
Après avoir mis l'interrupteur ON/OFF de l'onduleur monophasé sur ON, les câbles DC portent
une haute tension et les optimiseurs de puissance ne génèrent plus la tension de sécurité de
1V.

When the inverter starts converting power after the initial connection to the AC, the inverter
enters Standby mode until its working voltage is reached. This mode is indicated by the
flickering green inverter LED.

While the inverter is in Standby mode, it monitors the grid and verifies correct grid voltage and
frequency. The following message is displayed:
W a k i n g
R e m a i n i n g :
The countdown indicates the seconds remaining until Production mode is entered. 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. This
mode is indicated by the steadily lit green inverter LED.
