The Opta™ will receive instant consumption information from the energy meter's thresholds via Modbus RTU through the RS-485 interface. The power delivered by the solar panels will go through a series of processes to get to the energy meter. The domestic appliances will be controlled using the built-in relay outputs of Opta™. Other types of power sources can be used instead of solar panels.
