Optimising energy consumption
- Energy generation
- Optimised use of energy from a photovoltaic system.
- The goal is to optimally use the energy generated by a photovoltaic system and not feed surplus energy into the grid. A G2IA15A 4…20mA is connected downstream from the inverter and measures the current that is generated. The analogue value of the output is linked with the control electronics of a heat pump. A hot water buffer tank is heated depending on how much energy is available.
- - Optimised own consumption of the energy generated by a photovoltaic system
- Precise current measurement and processing of the recorded signal
