EPsolar or EPever Modbus RS485 Interface

This is a very specific IoT module being used to communicate to solar power controllers branded EPever of EPsolar. The RS485 to Serial module is shown connected to a RJ45 plug with standard ethernet cabling colours. 

The software only polls the solar power controller and receives back data on the status of battery, solar panels and load outputs, measuring input and output currents and voltages which is published to MQTT. The option to set parameters, including the time, or turn on the load, has not been implemented.
