Energy Measuring Device SMA Energy Meter

The Sunny Home Manager contains an integrated measuring device that corresponds to the measuring function of the SMA Energy Meter. If the Sunny Home Manager is installed at the point of interconnection, no further measuring device is necessary for the basic function. Where necessary, an additional SMA Energy Meter can be installed for measuring the PV generation power.

The SMA Energy Meter determines electrical measured values at the connection point and makes them available via Speedwire. The SMA Energy Meter can record energy flows in both directions (counting direction: grid feed-in and purchased electricity or PV generation). It can be connected both three-phase and single-phase.

The SMA Energy Meter is not an energy meter for measuring effective consumption in compliance with the EU directive 2004/22/EC (MID) The SMA Energy Meter must not be used for billing purposes.

The SMA Energy Meter and the Sunny Home Manager are licensed for a limiting current of 63 A per line conductor. From firmware version 1.02.04.R of the SMA Energy Meter, installations with more than 63 A per line conductor are possible if one external current transformer is used for each line conductor.

Additional material in the event of more than 63 A per line conductor from firmware version 1.02.04.R:

From firmware version 1.02.04.R of the SMA Energy Meter and for the Sunny Home Manager, installations with more than 63 A per line conductor are possible. With an SMA Energy Meter installation of more than 63 A per line conductor, one external current transformer is required for each line conductor. 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.
