In solar electricity systems, demand- and availability-controlled consumption of solar electricity plays a key role in cost-effective operation. This shows that different prioritisation of consumers can significantly increase efficiency while maintaining user comfort.
ET 255.03 contains two controllable electrical consumers that are prioritised differently. Two wire-wound tubular fixed resistors with different power consumption are used as consumers.
A consumer with lower power consumption is supplied with the highest priority. The lower priority is assigned to a consumer with higher power consumption.
Both electrical consumers can be switched on manually on the control unit or by a request from the GUNT software in ET 255. Settings in the energy management system in ET 255 ensure that consumers with lower priority are only supplied at certain times of day or depending on weather forecasts, for example.
The GUNT software in ET 255 controls the experiments. Typical generation and consumption profiles can be specified in the software via time-controlled sequences in order to investigate the optimisation of self-consumption under different operating options.
