Communication

The inverter provides various interfaces for communication purposes. These establish a connection to other inverters, sensors, energy meters, batteries or a link to the Internet.

• LAN
  LAN connects the inverter to the local home network, through which it can then access the Internet and solar portal. In addition, there is a second LAN interface on the inverter's communication board to which another device (e.g. inverter) can be connected.
• Wifi
  Via Wifi, the inverter can be connected to a Wifi router located in the local home network, giving it access to the Internet and the solar portal.
• Wifi access point
  The inverter offers a Wifi access point for initial commissioning. This can then be used to connect to a smartphone or PC and carry out the initial commissioning via the web-based installation wizard.
• WLAN bridge
  If there are several KOSTAL inverters in a system, the inverter can be used as a WLAN bridge to the WLAN router. Other inverters, energy meters or battery storage units can be connected via LAN cable to the inverter serving as a WLAN bridge to establish a connection to the local home network and beyond.
• RS485/Modbus (RTU)
  Energy meters are connected to the Modbus interface and record the flow of energy within the house.
