EN 62109 is a European Standard that discusses the safety measures for power converters used in photovoltaic power systems.
BS EN 62109-2 covers the particular safety requirements relevant to DC to AC inverter products. It also covers the products that have or perform inverter functions in addition to other functions, where the inverter is intended for use in photovoltaic (PV) power systems.
BS EN 62109-2 covers the inverters which may be grid-interactive, stand-alone, or multiple mode inverters. They 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.
Note: BS EN 62109-2 does not address grid interconnection requirements for grid-interactive inverters.
BS EN 62109-2 on power converters for photovoltaic power systems is useful for:
Photovoltaic power systems require specific power converters to convert the power generated into useful power that can be directly interconnected with the utility grid and/ or can be used for specific consumer applications locally.
BS EN 62109-2 lays out specific technicalities that should be considered in order to ensure the safety of the power converters for photovoltaic power systems, especially power inverters. It provides you with documentation and information related to installations, environmental requirements, and conditions for the installation of power converters for photovoltaic power systems.
BS EN 62109-2 guides you for safety measures to be followed that are specific to grid-interactive inverters which are similar to the safety aspects of some existing national grid interconnection standards.
Compliance with BS EN 62109-2 can assist you in ensuring the protection of photovoltaic power converters against various damages like electric shock and energy hazards, as well as electric shock fire hazards.
