iPLON Magic Box IEC-60870OVERVIEW

iPLON – “Magic Box”

iPLON Magic Box Standard Interface between the PV plant (rooftop or

Power Plant) and the Energy Utility Company

Based on the technical specifications of theGerman requirements of BDEW.

Control of the PV plant is achieved by theactive control of the inverters used in theplant.

Suitable for new plants as well as integratedin existing Power plants.

Standards (IEC 60870)

• 60870 standards are developed by IEC Technical

Committee 57 (Working Group 03)

– Define systems used for telecontrol (supervisory control

and data acquisition) in electrical engineering and power

system automation

– For controlling electric power transmission grids and other

geographically widespread control systems.

– use of standardized protocols, equipment from many

different suppliers can be made to interoperate.
