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.
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:
