EcoFlow EFA-ADL400-CT Three-Phase Smart Energy Meter (Smart Meter)

The EcoFlow EFA-ADL400-CT, reference 5008604013, is a three-phase smart energy meter designed to monitor electrical flows in compatible EcoFlow energy installations. With a rated current of up to 80 A, direct measurement with integrated current transformer, RS485 communication, and DIN rail mounting, it enables accurate recording of parameters such as voltage, current, active and reactive power, power factor, frequency, and imported or exported energy.

This Smart Meter is specifically designed to integrate with EcoFlow PowerOcean systems and other compatible solutions within the EcoFlow ecosystem. Its function is to provide the system with information about energy exchange between the grid, the photovoltaic installation, and the loads, allowing more precise monitoring and management of energy consumption and production.

Three-phase smart meter up to 80 A

The EFA-ADL400-CT is designed for three-phase installations and supports a rated current of up to 80 A. Unlike versions that use external current transformers, this model performs measurement through an integrated CT and is intended for installations where direct meter connection is possible.

EcoFlow specifies a rated voltage of 3 x 230/400 V AC and a frequency range of 45 to 65 Hz, suitable for common three-phase electrical networks in residential and professional installations.

Bidirectional energy measurement

The meter can record energy in both directions, so it can distinguish electricity imported from the grid from energy exported to it. This information is essential in self-consumption photovoltaic installations, as it makes it possible to know at any time whether the property is consuming energy from the grid or feeding surplus energy back into it.

In addition to imported and exported active energy, the unit can display other values related to the electrical behavior of the three phases, providing detailed information for system monitoring.

Extensive electrical parameter monitoring

The EcoFlow EFA-ADL400-CT can record and display different electrical quantities needed to understand the operation of a three-phase installation.

• Voltage: measurement of the three phases and phase-to-phase voltages.
• Current: independent measurement of the three phases.
• Active power: per phase and total.
• Reactive power: per phase and total.
• Apparent power: per phase and total.
• Power factor: per phase and total.
• Frequency: grid frequency monitoring.
• Active energy: total, imported, and exported recording.
• Reactive energy: total, imported, and exported recording.
• Harmonic distortion: display of values related to voltage and current.
• Phase angle: available from the device screen.

Integration with EcoFlow PowerOcean

The ADL400 meter has been specifically designed to work with the EcoFlow PowerOcean ecosystem. Once connected to the system, it provides the measurement data needed to understand energy flow between the grid, the loads, and compatible generation or storage equipment.

EcoFlow includes the EFA-ADL400-CT among the compatible three-phase meters for solutions such as three-phase PowerOcean, PowerOcean Plus, PowerOcean DC Fit, and other compatible equipment indicated in its selection guides. Specific compatibility should be checked according to the product, region, and installed version.

RS485 communication

Communication with compatible EcoFlow equipment is carried out via an RS485 interface. The meter features RS485A and RS485B terminals and uses Modbus RTU communication to transmit the recorded values to the system.

The communication speed can be configured between 1200 and 19200 bps. In PowerOcean installations, the meter connects to the corresponding METER port following the electrical diagram specified by EcoFlow.

LCD display for local reading

The Smart Meter includes an LCD display from which numerous electrical parameters can be directly consulted. The interface allows viewing voltage, current, frequency, power, power factor, imported and exported energy, and other system values.

This display makes commissioning and maintenance tasks easier, allowing the main data to be checked without the need for an external measuring device.

Accuracy for energy management

EcoFlow specifies an active power accuracy of 0.5% of the maximum range and a reactive power accuracy also of 0.5% of the maximum range. The meter also features a pulse output of 400 imp/kWh.

The maximum energy reading capacity reaches 9,999,999 MWh, allowing a long-term cumulative record of measured energy.

Compact DIN rail mounting

The EFA-ADL400-CT is designed to be installed inside electrical panels using a standard 35 mm DIN rail. Its dimensions are 72 x 65 x 90 mm, providing a compact format for integration alongside the rest of the installation's protection and control components.

EcoFlow specifies this model for indoor installation. The unit has an IP51 protection rating and CAT III installation category.

Ready for demanding operating conditions

The meter can operate within an ambient temperature range of -40 to 70 °C and with a maximum relative humidity of 95% non-condensing. These characteristics allow it to be used in electrical panels located in different indoor environments, always respecting the installation conditions established by EcoFlow.

Control of energy flows in photovoltaic installations

Integrated into a compatible EcoFlow installation, the EFA-ADL400-CT makes it possible to know in real time how energy flows between the electrical grid, the building's loads, and the photovoltaic system. These data are necessary for energy management solutions to identify consumption, production, and surplus energy and act according to the system configuration.

Its ability to measure up to 80 A in three-phase networks, RS485 communication, bidirectional measurement, and DIN rail format make the EcoFlow EFA-ADL400-CT a dedicated solution for adding energy monitoring to the EcoFlow ecosystem without the need for external current transformers.

Important: the meter must be installed indoors by qualified personnel and following EcoFlow's electrical diagram and safety instructions. Compatibility with each PowerOcean system or other EcoFlow product must be checked according to the installation version and configuration.
