SMA Commercial Energy Meter (600A)

The SMA Energy Meter EMETER-20 is a DIN-rail mounted energy meter for measuring grid feed-in and purchased electricity in PV and energy management systems. It supports Ethernet communication and can be used in three-phase or single-phase installations.

Key Features
Ethernet communication

Connects to a local router via Ethernet (10/100 Mbit/s, RJ45) for local network data exchange.

Three-phase and single-phase use

Provides bidirectional reading for three-phase systems and can also be used in single-phase installations.

External CT support above 63 A

Nominal current is 5 A/63 A, with currents above 63 A connected via external current transformers.

Compact DIN-rail mounting

Top-hat rail mounting in switch or meter cabinets with a compact enclosure and 4 DIN modules width.

Measurement performance

Measurement accuracy is stated at 1% with a 1000 ms measuring cycle.

Benefits
  • Supports bidirectional energy measurement for import and export recording.
  • Suitable for local network communication via Ethernet.
  • Can be used in single-phase and three-phase systems.
  • Compact form factor supports space-efficient DIN-rail installation.
  • Can accommodate higher currents when used with external current transformers.
