Balance-of-system components for photovoltaic systems. Design qualification natural environments1 Scope and object This International Standard establishes requirements for the design qualification of balance of system (BOS) components used in terrestrial photovoltaic (PV) systems. This standard is suitable for operation in indoor, conditioned or unconditioned; or outdoor in general open air climates as defined in IEC 6072121, protected or unprotected. It is written for dedicated solar components such as batteries, inverters, charge controllers,

Selection of calibration method depends on the facility available
