KNX gateway for SMA Inverters
The KNX gateway for SMA inverters provides a simple solution to transfer all relevant data from inverters to KNX. It allows integrators to take advantage of a fully integrated solar panel inverter, the data can be used to optimize energy consumption, monitoring, trending or to trigger specific action in the KNX installation.
- KNX Interface for SMA SUNNY BOY / TRIPOWER inverter serie
- Monitoring of Energy, Power, current, voltage, frequency, temperature,…
- Connected to the inverter over Ethernet
- Galvanic insulation from the KNX bus
- Configurable refresh rate of inverter data
- DIN rail mounted
- Auxiliary power supply 12-30VDC
- Advanced Logic functions including weekly calendar, sequences, math, logic gates and triggers.
DESCRIPTION
The KNX interface module INV-KNX is a KNX gateway for the SMA inverters. It provides KNX group object for all relevant values from the inverter. See below for the complete list of objects.
This gateway is intended to be used with an SMA inverter compatible with the SMA SunSpec modbus interface definition. The inverter is connected to the ethernet network on the same router as the KNX gateway.
CONNECTION
Elausys INV-KNX module is supplied from an external 12-30VDC power supply. An Ethernet RJ45 connector and a KNX connector provide access to the KNX bus and to the ethernet network. No additional component or wiring is required.
SOFTWARE
The KNX application software includes the following group objects. All group object are refreshed at a cyclic rate defined by an ETS parameters.
When the inverter is equipped with batteries, these information are also available on the KNX gateway.
Depending on the inverter model, not all of these objects may be available. See user manual for more details. In case your inverter model is not yet supported, please contact us to see the compatibility or possibility to include it.

Customer feedback
Gateway für Fronius Gen 24 und BYD HVS
Nicolas hat mich bei der Installation und bei der Funktionserweiterung unterstützt, er bietet einen super Support !
Danke nochmals an dieser Stelle. Gateway funktioniert einwandfrei !
Perfect Remote-Support to solve my problem
At the beginning there were difficulties with the Modbus communication between the Elausys Gateway and the SMA inverter.
All my attempts to find and solution for this problem failed. When I got stuck, i called the Elausys-Support-Team.
They connected to my site remotely. Luckily they was able to solve the challenge.
The SMA expects a special UnitID for communication with my SunSpec Profile (+123).
Again – thank you very much for your support!
Support for Battery integration
Hi,
i am More then happy with the great support of Nicolas. He implement me the Battery Status for my Solar Edge Battery within 1 hour!
Great product, great support.
thanks 🙂
Working very well and great support !
I use this module since 2 years (with a SE7K inverter), without any issues: well working and really stable !
And the support is very fast !
Thanks a lot for that !
Gateway for Solar Edge
works very good out of the box!
I like it !
Klasse Teil
Das Gerät hat vom ersten Programmieren an funktioniert. Einfach zu programmieren, einfach klasse 🙂
Great device and great support!
I bought the gateway for our SolarEdge SE10K. I had some problems during the installation and emailed ELAUSYS. After a TeamViewer session, all problems could be solved. The problem was with the inverter… The support was really fast, competent and friendly. Now everything works fine.
Gateway for Solar Edge inverters
INV-KNX- Gateway for Solar Edge inverters can translate between TCP modbus and KNX via ethernet connection. The Integrator has the ability to use almost 40 communication objects for monitoring and status.
Great - it works from first second.

Also very good support if you need (its simple).
