SMA Energy Meter

The SMA Energy Meter is a grid-connected energy meter for measurement and energy management in SMA PV systems. It provides phase-exact, balanced measured values for grid feed-in, purchased electricity and PV generation, with Ethernet communication for local network integration.

Key Features
Phase-exact, balanced measurement

Calculates phase-exact and balanced electrical measured values for energy management.

Three-phase bidirectional reading

Supports fast three-phase, bidirectional measurement for import and export values.

Ethernet communication

Communicates measured values via Ethernet in the local network using an RJ45 connection.

External current transformer support

Applications above 63 A can be connected via external current transformers.

Single-phase system use

Can also be used in single-phase systems.

Benefits
  • Supports frequent and precise measurement data for energy management
  • Can be integrated into local network-based monitoring and data communication
  • Allows measurement in systems above 63 A using external current transformers
  • Suitable for single-phase and three-phase systems
  • Low self-consumption of less than 3 W
Technical Summary

EMETER-20 energy meter with 230 V/400 V nominal voltage, 50 Hz/±5% frequency and 1% measurement accuracy. Rated current/limiting current per line conductor is 5 A/63 A, with loads above 63 A supported via external current transformers. Ethernet communication is via 10/100 Mbit/s RJ45. Dimensions are 70 x 88 x 65 mm, weight 0.3 kg, with top-hat rail mounting in switch or meter cabinets. Operating temperature range is -25°C to +40°C and ingress protection is IP2X.

Installation Notes

Top-hat rail mounting in a switch or meter cabinet. Connects to the local router via Ethernet cable (10/100 Mbit/s, RJ45 plug). External current transformers are required for applications above 63 A. Ambient operating temperature is -25°C to +40°C.

Efficiency

The meter can support increased self-consumption within SMA PV energy management systems. Self-consumption is below 3 W.
