The powerful measurement solution for intelligent energy management within the SMA Smart Home: The SMA Energy Meter takes phase-exact and balanced electrical measured values as a grid feed-in and purchased electricity meter and communicates these values via Speedwire. Thanks to its ability to quickly acquire measured values, the SMA Energy Meter is the ideal supplier of data for intelligent energy management within the SMA Smart Home. All PV generation data, purchased electricity and grid feed-in can be transmitted via standard Ethernet cable to the Sunny Home Manager, for example, or to the Sunny Boy Smart Energy. This, in turn, facilitates optimal energy monitoring, effective load and battery management and reliable active power limitation at the grid feed-in point while taking self-consumption into account.
Version 1.02.04.R (February 2014)
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.
Update SMA ENERGY METER:
Using the SMA Energy Meter with PV plants for self consumption will enable display of grid supply and feed-in. Depending on the selected graphical user interface (local WebUI or Sunny Portal/Sunny Places) also local consumption and generated PV power is displayed.
SMA Storage Systems always require an SMA Energy Meter for measurement of the grid connection point. This enables the optimal control for charge and discharge of the storage battery.
For selected energy management functionalities, the use of an SMA Energy Meter for measurement of the grid connection point is mandatory (e.g. Zero Export, prognosis based battery charging, ...)
The following devices can be used with an SMA Energy Meter:
