SPECIAL NOTICE : If you are purchasing this part for a self build project, please see our terms & conditions. FULFILLED BY PHOTONIC UNIVERSE : This product is fulfilled by Photonic Universe, our Solar partner.



As an official distribution partner of Morningstar products across the globe, we are proud to offer solar charge controllers and peripherals from this world-leading supplier. Innovative design from years of dedicated research and superior build quality enable this top-of-the-range network converter to provide detailed monitoring and customisation of Morningstar solar charge controllers.

This Morningstar EMC-1 Ethernet Meterbus converter enables remote access and monitoring of a Morningstar solar charge controller through a network connection - even if the Morningstar device does not support this on its own. Powered from the same battery as the charge controller, the EMC-1 can convert a Meterbus (RJ-11) or RS-232 comms port into a web-compatible Ethernet port (RJ-45) to allow monitoring of the device through the internet or a local area network (LAN).

The Morningstar EMC-1 is compatible with:


By connecting to the device through a web browser, the Morningstar LiveView interface displays real-time data, faults and alarms and enables the user to remotely amend network settings. Once connected, the solar charge controller can be monitored remotely from any PC, laptop, or mobile device on the same network, or even anywhere in the world through the internet (some network setup required). Morningstar LiveView is therefore ideal for solar charging systems in remote or difficult to access locations, as it eliminates the need to visit the installation site to monitor the system.

If the device is connected directly to a computer, the free MSView PC software is a useful tool for users seeking in-depth analysis and specific requirements for their charge controllers. MSView unlocks access to a wide range of options for viewing data including graphical displays and for customising device functions such as automatic data logging (not available for SunSaver Duo) and setting custom battery charging parameters.

The official Morningstar cloud-hosted data service, if available, will back-up the data broadcast from the device and provide easy access to data logs through the internet - even while the device is offline.

This device operates in a wide temperature range, making it suitable for use in a variety of climates with a system voltage ranging from 8V to 80V. For simplified installation, the converter will auto-detect a connection to compatible Morningstar devices and automatically configure the settings.

A switch on the converter enables/disables the remote configuration function - preventing unintended changes to settings once setup is complete. LEDs on the unit indicate power and connection status.

This unit is supplied with an Ethernet cable, battery cables, and a Y-cable for Meterbus and RS-232 connections. The converter can be mounted with screws (included) or slid onto a DIN rail.
