Step 2, Pairing Power Optimizers To The Inverter - SolarEdge SE3500 Installation Manual

Chapter 4: Commissioning of the facility
7 Verify that the following information appears on the LCD panel: 7 Verify that the following information appears on the LCD panel:
• P_OK: only appears during the first telemetry reception from the power optimizers. It indicates that the P_OK: only appears during the first telemetry reception from the power optimizers. It indicates that the
connection with power optimizers at least one power optimizer sends control data. If P_OK does not appear,
check the power optimizer, string and DC input connections.
• 000/000: only appears during the first telemetry reception from the power optimizers. Indicates the number 000/000: only appears during the first telemetry reception from the power optimizers. Indicates the number
of power optimizers that have been set in pairs on this inverter. At this point, the number should be 000,
since no power optimizer has been paired.
•
S_OK: the connection to the SolarEdge Monitoring Portal is successful (should appear only if the inverter is S_OK: the connection to the SolarEdge Monitoring Portal is successful (should appear only if the inverter is
connected to the server). S_OK if not displayed and the inverter is connected to the server, refer to the Appendix A: connected to the server). S_OK if not displayed and the inverter is connected to the server, refer to the Appendix A:

• Vac [V] - the AC output voltage. Check that the value is correct. Vac [V] - the AC output voltage. Check that the value is correct. Vac [V] - the AC output voltage. Check that the value is correct.
• Vdc [V] - the DC input voltage of the longest chain connected to the inverter. A safe 1V voltage will be required Vdc [V] - the DC input voltage of the longest chain connected to the inverter. A safe 1V voltage will be required Vdc [V] - the DC input voltage of the longest chain connected to the inverter. A safe 1V voltage will be required
for each power optimizer in the string.
NOTE :
A measurement error of ± 3V on the LCD screen of the inverter is acceptable.
• Pac [W] - the AC output power (will be 0.0 if the UPS is off). Pac [W] - the AC output power (will be 0.0 if the UPS is off). Pac [W] - the AC output power (will be 0.0 if the UPS is off). Pac [W] - the AC output power (will be 0.0 if the UPS is off).
• OFF - The ON / OFF switch of the inverter is in the OFF position. OFF - The ON / OFF switch of the inverter is in the OFF position.
Step 2, Pairing Power Optimizers to
UPS
Once all connections are made, all the power optimizers must be logically paired to their inverter. Power optimizers do not
start producing power until they are coupled with an inverter. This step describes how to assign each inverter to a power
optimizer from which it can produce energy. Perform this step when the modules are exposed to sunlight.
