Step 3, Verifying Proper Operation

After the proper wake-up delay time is over, the following message appears on
the inverter's LCD panel:
V a c [ v ]
2 3 0 . 7
P _ O K :
►
To verify proper operation:
1
Verify that the inverter LED is steady green.
2
Verify that the ON/OFF indicator on the LCD panel, described above, reads ON.
3
Verify that P_OK appears to indicate a connection to the power optimizers.
Also, verify that S_OK appears, if the inverter is connected to the SolarEdge
Monitoring Server.
4
Verify that the total number of power optimizers connected to the inverter
appears next to the P_OK indicator on the LCD panel. If this number is too
low, then it may mean that one or more of the power optimizers are not
connected properly or the pairing process may have not been completely
successful, for example due to complete shading of one of the modules or
insufficient sunlight during the pairing process.
NOTE:
It can take up to 15 minutes for all power optimizers to transmit their telemetries
and to be counted on the LCD screen.
5
Verify that the Vac [v] on the LCD panel specifies the grid's correct AC
output voltage in Volts.
6
Verify that the Vdc [v] on the LCD panel specifies the DC input voltage in
Volts, which should be between 250 V and 450 V in the single phase inverter
and between 550 V and 950 V in the three phase inverter.
7
Verify that Pac [w] on the LCD Panel specifies the total AC output power
produced, in Watts.
Congratulations! Your SolarEdge power harvesting system is
now operational.
