This Part 2 of IEC 62109 covers the particular safety requirements relevant to d.c. to a.c. inverter products as well as products that have or perform inverter functions in addition to other functions, where the inverter is intended for use in photovoltaic power systems. Inverters covered by this standard may be grid-interactive, stand-alone, or multiple mode inverters, may be supplied by single or multiple photovoltaic modules grouped in various array configurations, and may be intended for use in conjunction with batteries or other forms of energy storage. Inverters with multiple functions or modes shall be judged against all applicable requirements for each of those functions and modes. NOTE Throughout this standard where terms such as "grid-interactive inverter" are used, the meaning is either a grid-interactive inverter or a grid-interactive operating mode of a multi-mode inverter This standard does not address grid interconnection requirements for grid-interactive inverters.
