KNX gateway for Huawei Inverters

The KNX gateway for Huawei SUN2000 inverters provides a simple solution to transfer all relevant data from Huawei 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 Gateway for solar inverters
  • KNX Interface for Huawei SUN2000 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


The KNX interface module INV-KNX is a KNX gateway for the Huawei SUN2000 inverters. It provides KNX group object for all relevant values from the inverter. See below for the complete list of objects. 

This interface is intended to be used with a SUN2000 inverter. The inverter must be connected to the local WIFI network.

Huawei 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.

INV-KNX gateway connection


The KNX application software includes the following group objects. All group object are refreshed at a cyclic rate defined by an ETS parameters.

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.
