Legally defined compensation rate that grid operators must pay to plant operators for solar power fed into the grid.

Bidirectional or separate electricity meter that records the energy fed into the public grid by a PV system.

Software and hardware solution that intelligently monitors, controls and optimises energy generation, storage and consumption within a building.

Electrochemical system that stores excess PV energy and feeds it back into the home grid on demand to increase self-consumption.

Protective device that disconnects the circuit within milliseconds when dangerous differential currents occur between live and neutral conductors.

Standardised bus system for building automation that connects actuators, sensors, and control devices via a shared data cable.

Automatically tripping protective device that interrupts circuits during overcurrent and short circuit, and can be manually reset.

System that converts sunlight into electrical energy using solar cells, comprising modules, an inverter, and grid-feed or storage components.

Electrical connection of conductive parts to equalise electrical potentials and protect against dangerous touch voltages.

Electrical connection of all conductive bodies in a building to prevent dangerous voltage differences between metal parts.

Digital electricity meter with a communication interface that records consumption data in real time and transmits it bidirectionally.

Digital electricity meter with a communication interface that records consumption data in real time and exchanges it bidirectionally with the grid.

Device that converts the direct current of a PV system into grid-compliant alternating current at 50 Hz and 230/400 V.

Wireless communication protocol based on IEEE 802.15.4 for low-power smart home devices featuring mesh network topology and low data rates.
