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

DESCRIPTION

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.
