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.
Connects to a local router via Ethernet (10/100 Mbit/s, RJ45) for local network data exchange.
Provides bidirectional reading for three-phase systems and can also be used in single-phase installations.
Nominal current is 5 A/63 A, with currents above 63 A connected via external current transformers.
Top-hat rail mounting in switch or meter cabinets with a compact enclosure and 4 DIN modules width.
Measurement accuracy is stated at 1% with a 1000 ms measuring cycle.
SMA Energy Meter EMETER-20, Ethernet-connected energy meter with RJ45 10/100 Mbit/s communication. Nominal voltage 230 V/400 V, frequency 50 Hz ±5%, nominal current/limiting current per line conductor 5 A/63 A, with >63 A via external current transformers. Measurement accuracy 1%, measuring cycle 1000 ms. Dimensions 70 x 88 x 65 mm, weight 0.3 kg, top-hat rail width 4 modules. Protection class II, IP2X, ambient temperature –25°C to +40°C.
Top-hat rail mounting for switch or meter cabinets. Connection to the local router is via Ethernet cable with RJ45 plug. The device is specified for ambient temperatures from –25°C to +40°C and non-condensing humidity from 5% to 90%.
The datasheet notes that integrating the SMA Energy Meter can support increased self-consumption and cost savings. Self-consumption of the meter is <3 W.
