| Classification | Description |
|---|---|
| Daily inspection |
Daily checkup to maintain the basic functions of photovoltaic power facilities A checklist is used to examine any symptoms of the device from outside such as abnormal noise, smell, damage, etc. If trouble is detected, the extent of malfunction is analyzed, and measures are taken accordingly. Troubles are documented and reflected on the regular inspection so that proper measures can be taken. |
| Regular inspection |
Plans are established to check and maintain the device’s functions. In principle, the panel switch is turned off to check the device in no-voltage state. If necessary, the device is disassembled for inspection. If the device needs to be inspected without cutting off power, attention is paid to prevent any damage or accident. |
| Special inspection |
A measure is taken upon detecting trouble or after an inspection in compliance with the legal safety check criteria (regular inspection on electric safety within 4 years in accordance with Annex 10, Article 65 of the Electric Utility Act). |
| Maintenance inspection |
Advance inspection and maintenance in compliance with safety standards |
