Step 2: Pairing Power Optimizers to the Inverter

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. If the string length is changed or a power
optimizer is replaced, repeat the pairing process.
1. Perform pairing: Press and hold down the inverter LCD OK button (rightmost on the communication
board; see Figure 18) for about 10 seconds. The following message is displayed:

Keep holding for 5 seconds until the following is displayed:
P a i r i n g
T u r n
2. Turn the inverter ON/OFF switch to 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:
P a i r i n g
R e m a i n i n g
3. 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 62. If the
problem persists, contact SolarEdge Support. When pairing succeeds, the following message is
displayed:
P a i r i n g
P a i r i n g
4. Upon pairing completion, the inverter continues with assigning numbers to the power optimizers and
mapping them into strings:
Power optimizer detection - t he power optimizer IDs are detected and each optimizer is assigned a
l
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
l
detection is performed while some optimizers are set to MaxVout mode.
The detection and assignment of power optimizers may take u p to 2 minutes.
The system startup process begins:
Since the inverter is ON, the power optimizers start producing power and the inverter starts converting
AC.
