EM118019-02 is a class B single-phase two-wire digital energy meter. It adopts RS485 communication, DIN rail type instrument installation, has bidirectional measurement function (active forward and reverse measurement) and complies with EN50470-1/3 standard. What's more this PV solar meter are fully MID approved. single phase meter is one of the world’s most compact metering devices allowing the unit to be used in metering installations where space is at a premium The meter provides measurement of active (kWh) energy in both import and export directions with registers shown on the large easy to read LCD display. The display features 8×3.5mm characters and can be configured to auto cycle any of the available registers or remain static with only a single register viewable. The meter features an optical port conforming to IEC 629056-21 allowing meter readings to be collected electronically using a standard probe and software tool. The port also allows configuration of the meter. The electronic meter is highly reliable and capable of withstanding high voltage events and overcurrent without failure. The meter is resistant to tamper with reverse energy fraud detection and sealing for life. High quality solid brass cable terminals are used allowing 100 Amp operation.

Product Application
The term bi-directional metering refers to the fact that the meter can measure the flow of electricity in two directions. It measures how much energy comes from your electric company – “kWh delivered.” It also measures the difference between the generators production and the customers load demand – “kWh received.”
This bi-directional energy meter EM118019-02 is an electric energy meter that can simultaneously measure the electricity consumption and power generation. The power and electric energy are directional. From the perspective of power consumption, the power consumption is considered as positive power or positive energy, while the power generation is considered as negative power or negative energy. The bi-directional energy meter can measure, store and display electric energy separately in forward and reverse directions. At the same time, the meter can be equipped with standard RS485 communication interface to realize the remote transmission of data.
