KOSTAL and Kiwigrid bring dynamic electricity tariffs, tariff-optimised charging and maximum flexibility directly to your home
Solar trends & topics
The energy world is changing – and KOSTAL provides the answers to today's and tomorrow's trends and issues. From backup power solutions and dynamic electricity tariffs to cyber security.
Ready for dynamic electricity tariffs
KOSTAL is ideally prepared for the use of dynamic electricity tariffs – for end customers and installers alike. With an optimally coordinated system consisting of an inverter, wallbox and battery storage unit, KOSTAL offers a future-proof, updateable and standard-compliant energy system.
Functions such as ‘intelligent battery usage’ enable electricity storage devices to be charged specifically when tariffs are low. The ‘Time Mode’ of the KOSTAL wallbox ensures that electric cars are automatically charged at low prices. Thanks to automatic software updates, all components remain technically up to date.
This reduces electricity costs, increases independence from the energy market and actively supports the energy transition. KOSTAL thus provides an economically and technically sophisticated solution for the requirements of tomorrow.
Just in case: The KOSTAL BackUp Switch as a simple first power solution
KOSTAL is ideally prepared for the use of dynamic electricity tariffs - for end customers and installers alike. With an optimally coordinated system consisting of inverter, wallbox and battery storage, KOSTAL offers a future-proof, updatable and standard-compliant energy system.
Functions such as "intelligent battery utilisation" make it possible to charge energy storage systems at favourable tariffs. The "Time Mode" of the KOSTAL Wallbox ensures that e-cars are automatically charged at low prices. Thanks to automatic software updates, all components remain technically up to date.
This reduces electricity costs, increases independence from the energy market - and actively supports the energy transition. KOSTAL thus provides an economical and technically sophisticated solution for the requirements of tomorrow.
