KOSTAL Energy Meter MP the ideal supplement for single-phase grids
For precise energy recording and a single-phase measurement solution - compact, quick to install and optimally matched to the KOSTAL PLENTICORE MP inverter

KOSTAL Energy Meter MP: Single-phase electricity meter for PV systems
The KOSTAL Energy Meter MP is the new single-phase electricity meter from KOSTAL for photovoltaic systems. The Energy Meter has been specially developed for households with a single-phase grid connection and impresses with its simple installation, seamless system integration and precise energy data.
Whether for optimising self-consumption, for dynamic feed-in management or as a basis for smart energy applications - the KEM MP provides reliable information on energy flow, consumption and feed-in. It really comes into its own in combination with KOSTAL PLENTICORE MP inverters: plug & play, automatic device recognition and maximum measurement accuracy.
Thanks to its compact design, the Energy Meter MP can be installed quickly and space-savingly on the top-hat rail. Communication is simple via Modbus TCP over Ethernet - perfect for integration into existing energy management systems or the KOSTAL Solar Portal.
Systematic smart energy solutions: the single-phase KOSTAL Energy Meter MP adds precise measurement data and optimised system integration to photovoltaic systems.
