What is BS EN IEC 62909-1 - Bi-directional grid power converters about ?
BS EN IEC 62909-1 is an international standard that discusses the general requirements of Bi-directional grid connected power converters. This is a circuit that can convert a commercial power supply (AC) and internal DC in both directions and exchange energy.
BS EN IEC 62909-1 specifies general aspects of bi-directional grid-connected power converters (GCPC), consisting of a grid-side inverter with two or more types of DC-port interfaces on the application side with system voltages not exceeding 1 000 V AC or 1 500 V DC. In special cases, a GCPC will have only one DC-port interface, which is connected to a bidirectional energy-storage device.
BS EN IEC 62909-1 includes terminology, specifications, performance, safety, system architecture, and test-case definitions. The "system architecture" defines the interaction between the inverter and converters. Requirements that are common, general, and independent of special characteristics of individual generators and bi-directional storages are defined.
Note: BS EN IEC 62909-1 does not cover uninterruptible power supply (UPS) systems, which fall under the scope of IEC 62040 (all parts). Requirements for internal and external digital communication might be necessary, the interface requirements including communication with distributed energy resources are provided in a future part of IEC 62909. All EMC requirements are defined by reference to existing IEC standards. External communication requirements are out of the scope of BS EN IEC 62909-1.

BS EN IEC 62909-1 on Bi-directional grid connected power converters applies to:
- Manufacturer of the bidirectional converter
- Electrical engineer
- Quality testing personnel
Why should you use BS EN IEC 62909-1 - Bi-directional grid power converters ?
A bi-directional grid-connected power converter is a power converter connected to the grid by a bi-directional inverter with multiple DC-port interfaces. This is a circuit that can convert a commercial power supply (AC) and internal DC in both directions and exchange energy.
BS EN IEC 62909-1 provides you with the advanced standardization of a bi-directional grid-connected power converter (GCPC) which combines the source of power generation and the storage battery. This part of IEC 62909 provides common general requirements independent of special characteristics of individual applications.
BS EN IEC 62909-1 provides you with nano-grid systems which are especially suited to increasing energy-usage efficiency and reducing power consumption of homes by combining and optimally controlling energy storage with generators.
As a user of BS EN IEC 62909-1, you can be ensured of the general requirements for bi-directional grid connected power converters.
