Maintenance Schedule

Following the inverter's commissioning, the inverter must be
maintained on an appropriate schedule, fitting to the
installation. To establish the correct periodic maintenance
schedule, an initial check-list is provided in the table below.

Comments
1) Record in Maintenance Log
2) Develop site-specific needs
3) Helpful recommendations
Based upon the initial 30-day and 6-month findings, develop and
schedule recurring (periodic) maintenance tasks to ensure proper
field-wiring torque.
After the initial 30-day and 6-month inspection:
■
Annual Inspection and checks of the inverter is required,
■
minimum.
Field wiring (PV and AC connection points)
❑
❑ Inverter
❑ internal wiring and components
❑ Filter-Capacitor inspection
❑ Solar System external to the inverter
Inspect: Clean or Replace as Required
Excessive environmental dust that will require more periodic filter
checking and cleaning.
What is the cause of the filter dirt?
Local (temporary) construction or activity
■
■ Long-term (chronic) air contaminates
❑ Increase periodic filter maintenance/change
Is there any undue water or moisture ingress?
■ Loss of seals
High (condensing) Humidity
■
Local flooding or Splash
■
Overall exterior condition
■
■ Overall Interior Condition
Has the Inverter performed as Expected?
If Not, Why?
