Who it’s for
A single-phase smart energy meter for the electrical panel, with two 50 A current transformers, so you can measure two circuits separately: for example home consumption and solar production, or the home and a charging station. Supports Ethernet and Modbus. A small meter for a single circuit is EM Mini Gen4, and for 3-phase there’s 3EM-63W.
What to know before installing
- Takes up one module on the DIN rail.
- Two 50 A current transformers are included.
- It has a small dry-contact relay (2 A) for driving a contactor.
- Wi-Fi or Ethernet connection.
FAQ
Can it measure solar production and consumption together?
Yes. Each current transformer measures a different circuit, and metering is bidirectional.
Can it shed a load when consumption is high?
Yes, through the built-in relay that drives a contactor.
Is it suitable for a 3-phase home?
No, it’s single-phase. For 3-phase, see the energy meters category.
