DANSK DSF/PREN 62446-2 [ Draft ]

This Part 2 of IEC 62446 describes basic preventive, corrective, and performance related maintenance requirements and recommendations for grid-connected PV systems. The maintenance procedures cover: • Basic upkeep of the system components and connections for reliability, safety and fire prevention; • Measures for corrective maintenance and troubleshooting • W orker safety The standard also addresses maintenance items for maximizing anticipated performance such as module washing and upkeep of vegetation. Special considerations unique to rooftop or ground-mounted systems are summarized. This standard does not cover off-grid systems or systems that include batteries or other energy storage, however parts may be applicable to the PV circuits of those systems. The confirmation of a system’s compliance with the appropriate design and installation standards is covered in Part 1 and takes place during initial project commissioning. Maintenance of PV systems is often lumped into the catch-all term operations and maintenance (O&M.) This standard does not address business or management operational processes (e.g. forecasting, utility pricing incentives, etc.) or other considerations driven by factors outside of basic system working condition, safety and performance.
