Energy monitor smart-MAIC D103 for 3−Lines grid
with Current Transformer type Ring up to 100A

The energy monitor is a ready-to-use device for 3-phase WYE grid with neutral or 1-phase three-point measurement and uses three ring current transformers up to 100A.
If you read the manual, it's not difficult to install. Connect the energy meter to your Wi-Fi point and the data will be sent to the cloud server once a minute.
You can analyze electrical energy, power, voltage, current using the Dashboard and with no time limits.

Smart meter D103 produced in Standard and Extended version.

In the Extended version, the smart meter provides separate bi-direction metering of power consumption and generation, and 5 second data intervals for API and MQTT.
In the Standard version, the device measures one-way power and 1 minute data intervals for API and MQTT.
