DETAILED DESCRIPTION

EMS is an all-in-one smart meter, gateway, web-server and controller. It is an energy analyzer that can monitor one three phase load (or 3 single- phase loads), expandable to 10 three-phase loads via ESY bus addons.

EMS is a gateway that supports several communication protocols including Modbus (TCP/IP and RTU), BACnet IP, FTP, FTPS, SFTP, Rest-API and MQTT which allow for rapid integration with third- party software and any other device connected to the network (e.g., building energy management systems and inverters or charging stations).

EMS is a stand-alone controller: with two Ethernet ports, RS485 ports and Wi- Fi communication for an easy and simple programming via smart- phone; energy data readings can be pushed to external servers/Cloud and can be stored in the internal memory of the device.

EMS is a web server: for data analytics presented via dashboards, charts and reports.

By combining accurate metering, a powerful Linux powered CPU in a small case, EMS is really a complete Energy Management System in a box.

Direct connection of up to 65 A or full compatible with any 333 mV current transformer and with any current transformer with 5 A secondary current. It can be installed in systems with rated current up to 10 kA, even in retrofit applications if used with openable transformers like CTA or CTD S.

Main metering functions

• Measure active, reactive and apparent energy

• Measure the main electrical variables

• Measure the load/analyser run hours

• Measure the total harmonic distortion (THD) of current and voltages

• Multi Load monitoring via plug'n play ESY BUS add-on modules

Main IoT features

• Self power supply via voltage inputs

• Data transmission via Modbus BACnet, MQTT, FTP, SFTP, FTPS, Rest-API

• Embedded Wi-Fi for easy programming/data analysis

• Reliable data storage within the embedded database

• Data analytics organized in dashboards and widgets

• Display analytics based on the stored data via the embedded web server

• Embedded reporting system (scheduled or on-demand reports)

• Secure multi-user access either local (embedded web app) or remote (MAIA Cloud)

• Remote access and firmware update via MAIA Cloud (commissioning and troubleshooting)

• Two Ethernet ports (switch mode for easy cascading of connected devices)

• BTL certified

• IoT certification for Amazon AWS and Microsoft Azure

• Embedded display for diagnostics and variables

The advantages of EMS that make it unique

• All- in- one Energy Management System: fully integrated smart meter, data logger, gateway, web server and controller.

• High measurement accuracy.

• User-friendly installation and set up: the start- up and each function can be managed and configured by a unique web app (compatible with PC and smartphones).

• Real-time data acquisition.

• Accurate and reliable 3-phase energy measurement for consumption and feed-in.

• Scalability: it is easy to scale up the system thanks to additional ESY accessories.

• Interoperability. By leveraging its automation- server functions, it is easy to exchange data with other systems via FTP, SFTP, FTPS, SMTP, Rest- API, MQTT, Modbus and BACnet.

• Generic MQTT compatibility: EMS can send real-time data and data can be stored in the EMS database to a generic MQTT broker. Moreover, EMS has been validated for working with Azure IoT and is compatible with Amazon AWS IoT.

• Powered by MAIA Cloud: secure and reliable system for remotely managing, setting and operating EMS units Worldwide.

• Optimised user interface and data management. Improved user experience for fast commissioning and easy daily operation thanks to a multi-user system.

• Over- the- Air (OTA) Updates. Seamlessly update the firmware of multiple deployed devices remotely via the MAIA Cloud portal, ensuring continuous improvement and maintenance without onsite intervention.

• Quick configuration. The configuration wizard that runs when the system is started for the first time allows you to put the unit into operation without errors and in few seconds.

• Cybersecurity (IoT Security Rating): Security Capabilities Verified by UL to Level SILVER for EMS (Security Enhancement).

• Optional Open-EM system: for allowing third party software modules to be embedded into EMS so to build custom solutions for specific applications.
