7.6 Completing Commissioning
If all the start-up procedures have been performed, check the operating condition of the
PCS.
• Check whether there are anomalies of the PCS: abnormal noise, overheating, smoking
or unusual odor.
• Check the PCS grid-connected voltage, current and THD for unstableness.
• Check the grounding of the PCS enclosure.
• Check the functionality of the WEB display.
• Record accurately the PCS operation data during commissioning.
The duration of commissioning depends on the plant scale, plant location, on-site environ-
mental conditions and so on. Usually, if the in-site condition is good, the commissioning can
last for 1 week, i.e. 168 hours.
The commissioning of the PCS is completed. The PCS operates normally.
After commissioning, the plant starts power generation and enters the daily maintenance
process.
