The Ethernet MeterBus Converter™ (model: EMC-1) provides the data and communications connection for Morningstar devices, between themselves, with surrounding systems, and with the outside environment through the internet. It’s simple to connect to Morningstar products equipped with an RJ-11 Meterbus port to enable remote monitoring, custom programming, and access to future cloud-based data services.
Protocols and technologies supported by the EMC-1 include:
The EMC-1 converts this connection into a fully enabled Ethernet port allowing data transfer to the internet. Once connected, the MeterBus port enables transmission of serial data to the EMC-1 for remote monitoring, configuration, and control, using any type of IP-based network connection. This way, many new, powerful integration options for Morningstar products can be activated and used in remote power systems.

This 3 minute video provides an overview of Morningstar’s new Ethernet MeterBus Converter (EMC-1). This device enables IP based network and internet connectivity to any Morningstar solar charge controller or inverter that features an existing MeterBus port (RJ-11) including: PWM controllers: TriStar and SunSaver Duo; MPPT controllers: TriStar MPPT, ProStar MPPT, & SunSaver MPPT; Inverters: SureSine. And future products that feature an existing MeterBus port (RJ-11).
View this recorded webinar to learn about the new Ethernet MeterBus Converter which enables the addition of IP based network and internet connectivity to any Morningstar product that features an existing MeterBus port (RJ-11).

It’s a recommended best practice to install your product’s latest firmware to ensure access to all up-to-date features, accessory compatibilities, and code modifications. Follow instructions in the EMC-1 Firmware pdf to locate the most up-to-date firmware. Then, watch this video for instructions on how to update EMC-1 firmware.
The diagram above shows how connections are made with the RJ-11 cord between the Morningstar product on the right and the EMC-1 in the middle. The EMC-1 is connected to an Ethernet gateway which is typically a router or switch that you see on the left.
Select Morningstar products that previously could not connect to an IP network or internet can connect to the EMC-1 to enable a view of many useful system metrics via web browser such as:
This information will appear live in real time, so you will see data changing without having to refresh your browser. Furthermore, you can use our free MSView software with the EMC-1 so you can change your battery charging settings, low voltage disconnect settings, and lighting settings. Every product in MSView has its own setup wizard for adjusting the custom settings. To make it easier to use MSView setup wizards, we’ve created a webpage that lets you download custom settings configuration files.
The schematic diagram above, illustrates how the ProStar MPPT regulates power to batteries and an alternating current (AC) load in an off-grid system. This diagram is very similar to the DC load diagram above it except an inverter has been added.
