Appendix B: Maintenance

This appendix describes how to perform preventive maintenance to the inverter. By
performing these preventive maintenance tasks, you can help keep the inverter
functioning properly and avoid potential problems.

Routine Maintenance of the Inverter

Performe a yearly mechanical inspection of the mounted solar inverter to ensure its
proper and efficient functioning, and prolonging its lifespan.
Visual Inspections
By performing these inspection steps, you can help ensure that your inverter is installed
safely:
1. Check the mounting of the inverter: Check that the mounting brackets of all units
are secured to the wall and not showing signs of wear or damage or corrosion. Make
sure that the units are firmly installed.
2. Inspect the physical condition: Inspect the physical condition of the inverter
enclosures. Check for cracks, dents, and other physical damage. Ensure that all
screws securing the front panel are in place.
3. Check the ventilation: Check that the cooling fan, at the bottom of the Synergy
Units, operate and that air can freely flow around the inverter.
4. Check the conduit connections: Inspect the physical condition of the conduits.
Ensure that conduits are secured properly to the inverter, and to the wall.
5. Check the wiring glands: Check that the unused openings in the communication
glands, at the bottom of the Synergy Manager, are sealed. Check that the port of the
battery bank input is covered.
6. Check the wiring connections: Check the cables between the Synergy Manager and
the Synergy Units. Make sure that the plugs are connected properly and secured.
Check that the cables are not damaged. If cables are disconnected, immediately
power-off the inverter.
7. Checking Ground Connections: Check that all Ground (PE) wires are tightly
connected to all enclosures of the inverter.
Ground Connection
The following process should only be done by a qualified electrician or someone with
the proper training and equipment to avoid electrical hazards.
