What is BS EN IEC 63112 about? 
BS EN IEC 63112 is applicable to low voltage Photovoltaic Earth-Fault Protection Equipment (PV-EFPE) whose function is to detect, interrupt, and warn system operators of earth faults in solar photovoltaic arrays.
BS EN IEC 63112 specifies the types and levels of the monitoring and protection functions that may be provided, the nature and timing of responses to earth faults, test methods for validating the monitoring and protection functions provided, requirements for functional safety and fault tolerance, requirements for product safety including construction, environmental suitability, markings, documentation, and testing for photovoltaic (PV) arrays.
Who is BS EN IEC 63112 for?
BS EN IEC 63112 on photovoltaic arrays is relevant to:
- Companies dealing with solar energy cell/panel
- Manufacturers of photovoltaic arrays
- Manufacturers of protection equipment
Why should you use BS EN IEC 63112?
Photovoltaic array consists of multiple interconnected photovoltaic cells. These cells convert solar energy into direct-current electricity.
BS EN IEC 63112 specifies the requirements that are applicable to photovoltaic earth fault protection equipment whose function is to detect, interrupt, and warn photovoltaic systems operators of earth faults in solar photovoltaic arrays. A stand-alone standard is deemed necessary and appropriate because Photovoltaic earth fault protection equipment may be designed as stand-alone equipment or may be integrated into other equipment such as PV inverters, charge controllers, combiner boxes, etc.
Thus, as an user, BS EN IEC 63112 provides you the requirements which include product safety requirements covering the construction, environmental suitability, marking, documentation, and testing of the equipment, which helps in manufacturing photovoltaic arrays for earth fault protection equipment in a standardized manner.
