EMS is an all-in-one smart meter, gateway, web-server and controller. It is an energy analyser that can monitor one three phase load (or 3 single- phase loads), expandable to 10 three-phase loads via ESY bus add-ons. 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 a 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. By combining accurate metering, a powerful Linux powered CPU in a small case, EMS is really a complete Energy Management System in a box.

Benefits:

• All- in- one Energy Management System: fully integrated smart meter, data logger, gateway, web server and controller.
• High measurement accuracy. Security Capabilities Verified SILVER
• 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.
• Direct connection of upto65A.
• Scalability: it is easy to scale up the system thanks to additional ESY accessories.
• 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 on site 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.

ESY is three-phase current measurement accessory for the EMS system, compatible with 333 mV or 5 Acurrent transformers. The small size allows the module to be installed close to the loads to be monitored and thanks to the two RJ45 ports it is possible to easily connect up to 10 ESY devices in cascade to the EMS. Each ESY module is self-powered and is automatically found by EMS once it is connected to the ESY bus; the programming is done through the EMS web app.

Benefits:

• Compact housing. 1-DIN housing dimension to facilitate installation near the loads to be monitored.
• Multi-load management. The EMS system manages up to 10 ESY modules connected to it via the ESY bus network. Each ESY module manages up to three current channels and it is possible to distribute the measurements coming from the three current sensors in one or more loads.
• Self supply. The ESY devices are self powered by the ESY bus, therefore they do not require a separate power supply.
• Plug and play fast installation. Once connected to the ESY bus network via Ethernet cables, the device is automatically found by the EMS system.
