MU103
Metering unit for precise direct measurement at the grid connection point Direct measurement for submetering and energy management to the highest standards.
!NEW!
The MU103 is a compact, high-performance metering unit for direct measurement of energy flows at the grid connection point (NAP). Developed for applications in the smart home, commercial and industrial sectors, it provides precise measurement data for consumption and feed-in - the basis for efficient energy management in accordance with ISO 50001.
Thanks to its flexible connectivity and secure communication design, the MU103 is ideally suited for integration into home energy management systems (HEMS) - whether as a stand-alone gateway or embedded in systems such as inverters.
