7. Maintenance and Decommissioning of Inverters

This section defines the activities required to properly maintain the inverter and must be done by qualified personnel,

trained in the installation, decommissioning and maintenance of PV inverters.

7.1

Maintenance is required to ensure the inverter remains in proper condition, prolonging service life and preventing

potential issues.

7.1.1

Check Electrical Connections

Check all conductor connections as regular maintenance inspection every 6 months to one year, depending on the

temperature changes at the installation site.

Check the conductor/cable connections. If loose, tighten all the terminals to proper torque, referring to Chapter 3

Installation.

Check for damage to the conductor/cable jacket. Repair or replace any damaged conductors/cables.

7.1.2

Clean the Air Vent Grate

The inverter can become hot during normal operation. It uses built in cooling fans to provide sufficient air flow and to

help in heat dissipation.

Check the air vent grate regularly to make sure it is not blocked. Clean the grate with a soft brush or vacuum cleaner

attachment if necessary. The frequency of this cleaning depends on the installation environment.

7.1.3

Replace the Cooling Fans
