New firmware version 3.0 is now available for the SMART CONNECT KNX e-charge II!

With the update to version 3.0, the SMART CONNECT KNX e-charge II becomes the new centrepiece of your smart energy management. We have enhanced the device with key features that take the integration of solar power, energy storage and electric mobility to a whole new level.
The new energy monitor
Experience how simple smart energy can be: from photovoltaics and storage to wallboxes and heat pumps, generators and consumers are displayed clearly and visually in real time. You can immediately see how much power is being generated, stored or consumed and how much is currently being drawn from the grid (spoiler: maybe it's even zero?). The energy monitor not only makes energy visible, but also tangible – for maximum transparency in the smart home.
Thanks to modern building automation, you can see immediately:
- Is electricity from the PV system currently being used?
- How much power is the storage system supplying?
- Which devices are currently consuming energy?
- And how high is the grid consumption – or is it perhaps even zero?
And all this can be embedded in your favourite visualisation. See it where you need it!
§ 14a EnWG
Who enjoys reading legal texts? The new Section 14a of the German Energy Industry Act (EnWG) is a shining exception, as it directly benefits your wallet. Households and businesses benefit from significantly reduced grid fees if they use controllable devices such as wall boxes in a grid-friendly manner. In this way, you can actively contribute to the energy transition and, at the same time, ensure a more stable power grid.
It becomes particularly smart when the SMART CONNECT KNX e-charge II takes over as conductor. Especially with multiple consumers or your own PV system, it ensures that all components work together ideally and load peaks are reduced. In accordance with legal requirements, it enables the grid operator to actively control power consumption when necessary in order to avoid bottlenecks. Even in such situations, the SMART CONNECT KNX e-charge II offers maximum benefit, full control and secure energy management – which simply pays off.
Peak load management
The integrated peak load management system effectively prevents unnecessary peak loads and the associated surges in electricity rates. This saves on energy costs!
Even more freedom when choosing your device
We have expanded the list of supported hardware:
- Support for new charging points: Mennekes 4You500, Keba company car wallbox, Veton ONE/TWO/WALL and phase switching for Alfen wallboxes.
-
IIntegration of new inverters: KOSTAL Plenticore G3, Huawei 2000 KTL-L1/M1
Did you know? The e-charge can now also be used without charging points to provide ONLY information about the solar storage unit or inverter in the KNX.
