KNX gateway for SolarEdge Inverters

The KNX gateway for SolarEdge 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 Gateway for solar inverters
  • KNX Interface for SolarEdge 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

DESCRIPTION

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

This gateway is intended to be used with a SolarEdge inverter compatible with the 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.

INV-KNX gateway connection

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 an external powermeter, this 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.
