Monitoring The Solar System Performance - SolarEdge SE K Series Installation Manual

4. Inspect the wire connections: Visually inspect all wire connections, looking for signs
of damage, wear and tear, loose connections or overheating. If you find any signs of
damage, it's important to address them promptly to prevent further issues.
5. Ensuring tight DC connections: If your inverter is equipped with a spring-clamped
terminals, gently hold each wire and try to pull it out. Verify that all wires are locked
inside the terminals. If your inverter is equipped with a DC screw terminals, fasten
the screw of the terminals to a torque of 3.7 ft.*lb for 4 AWG wires or 5.9 ft.*lb for 3
to 2 AWG wires (see "Connecting PV Strings to the Synergy Manager" on page 52).
WARNING!
Wait five minutes for the input capacitors of the inverter to discharge.
AVERTISSEMENT!
Attendez cinq minutes pour que les condensateurs d'entrée de
l'onduleur soient déchargés.
6. Ensuring tight AC connections: Fasten the nuts of the AC terminals to a torque of
15.4 lb.*ft ( see "Connecting Ground and AC Wires to the Synergy Manager" on
page 56).
7. Check the wire insulation: Inspect the insulation on all wires for any signs of damage,
such as cracks, overheating or abrasions. If you find any issues, repair or replace the
wire as necessary.
8. Reconnect and turn on the inverter: Once you've completed the maintenance,
reconnect the inverter to the electrical source and turn it on. Monitor the inverter's
performance to ensure it's operating as expected.
General Cleaning
Clean the inverter: Dirt and debris can accumulate on the inverter over time, which can
reduce its performance. Clean the inverter regularly with a soft brush, a soft cloth, and
mild detergent to keep it functioning efficiently.

Monitoring the Solar System Performance

The SolarEdge monitoring platform enables to monitor PV strings connected to the
inverter. It provides accurate information about the present and past performance of
each PV module individually and the system as a whole. The platform enables to detect,
pinpoint and troubleshoot faults, efficiently manage maintenance operations, and
analyze site profitability.
