Commissioning Completion
After the inverter is successfully connected to the grid, the following tests need to be
performed:
If all the start-up procedures have been performed, check the operating condition of the
inverter.
Check whether there are anomalies: abnormal noise, overheating, smoking or unusual
smell.
Check the grid-connected voltage, current and THD for unstableness.
Check the grounding of the inverter enclosure.
Check the functionality of the LCD display.
If several inverters are commissioning at the same time, operate as per inverters connect to
the grid gradually. During commissioning, record accurately the running data of each
inverter.
The duration of commissioning depends on the plant scale, plant location, on-site
environmental 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 inverter is completed. Inverter operates normally.
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 assign a person to keep the keys.
