Universal recording of measured values for intelligent energy management


A high-performance measurement solution for intelligent energy management in PV systems with SMA devices. The SMA Energy Meter calculates phase-exact and balanced electrical measured values and communicates these via Ethernet in the local network. In this way, all data on grid feed-in and purchased electricity as well as PV generation by other PV inverters can be communicated to SMA systems frequently and with a high level of precision.

Integrating the SMA Energy Meter establishes, in all systems, an ideally coordinated system configuration that guarantees the highest performance and stability with the best cost savings and increased self-consumption.

Easy to Use

  • Quick plug-and-play installation
  • Graphic visualization of current measured values in Sunny Portal and local web UI


  • Space-saving, top-hat rail mounting in household distribution thanks to compact enclosure
  • Flexible use in applications > 63 A thanks to external current transformers
  • Suitable for universal use regardless of existing energy meter

High Performance

  • Fast three-phase, bidirectional reading for effective energy management*
  • Ideal coordination with SMA devices to ensure control tasks are carried out stably

* Can also be used in single-phase systems.

Version >= 2.0.15.R (April 2017)

Performance features:

Version transition from SMA Energy Meter 10 (EMETER-10) to SMA Energy Meter 20 (EMETER-20).
The SMA Energy Meter 20 is fully compatible with the previous version and can be used in all existing applications without limitation.

Version 1.02.04.R (February 2014)

Performance features:

More Flexibility – As of firmware 1.02.04.R, employment of the SMA Energy Meter will be also possible in applications >63A. Therefore the connection of external current transformers will be supported.

Recommendation for the current transformer: SMA Solar Technology AG recommends current transformers designed for a secondary current of 5 A. The current transformers should have at least accuracy class 1.
