• Recheck to ensure the inverter and switches upstream and downstream meet the
requirements and are flexible enough.
7.5 LCD Parameter Setting
When the LCD is on, set the LCD display language, date and time, communication

7.6 Completing Commissioning
If all the start-up procedures have been performed, check the operating condition of the
inverter.
• Check whether there are anomalies of the inverter: abnormal noise, overheating,
smoking, or unusual odor.
• Check the inverter grid-connected voltage, current, and THD are stable.
• Check the grounding of the inverter enclosure.
• Check the functionality of the LCD display.
• Record accurately the inverter operation data during commissioning.
The duration of commissioning depends on the plant scale, plant location, onsite
environmental conditions, and the like. Usually, if on-site condition is stable, the
commissioning can last for 1 week, i.e. 168 hours.
The commissioning of the inverter is completed. The inverter operates normally.
After successful commissioning, the inverter will be put into operation.
When the inverter is operating, make sure there are no flammable materials or
other materials within at least 5 meters around the installation site.
Local/national standards about the min. electric clearance around the inverter
should be respected.
The inverter needs no manual control in daily operation. Open the cabinet door
only for maintenance or troubleshooting and by qualified personnel only.
Keep the door closed and locked and store the keys of the door by appointed
personnel during normal operation.
