Verify that the
Vdc [v]
on the LCD panel specifies the DC input
voltage, in Volts. There should be a safety voltage of 1 V for each
power optimizer connected to the inverter.
NOTE:
A measurement error on the inverter LCD of ±3 V is OK.
NOTE:
If the LCD panel shows 0 V:
Verify that the PV modules are are not shaded or otherwise obstructed.
Check for proper power optimizer, string and DC input connection.
Verify the correct polarity of the DC input connection.

Verify that
Pac [w]
on the LCD Panel specifies
0
as the
AC output
power, in Watts. This is because the inverter is still off.
WARNING
!
Verify that the ON/OFF indicator on the LCD panel, described above, reads
OFF.
Step 2, Pairing Power Optimizers
to the Inverter
After all connections are made, all the power optimizers must be logically
paired to their inverter before they can start working with it. This step
describes how to pair power optimizers to the inverter, meaning to assign
each inverter to the power optimizers from which it will produce power.
NOTE:
The power optimizer does not start producing power until it is paired with an
inverter.
►
To pair the power optimizers to the inverter:
1
Turn the ON/OFF switch at the bottom of the inverter to off. Press the
inverter’s LCD Light button for
15 seconds
. The following screen is
