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. 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 button for about 10 seconds. The following
message is displayed:

Keep holding for 5 seconds until the following is displayed:

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:

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 95. If the
problem persists, contact SolarEdge Support. 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!
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.
