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 existing WLAN router. Additional inverters, energy meters or battery storage can be connected to this inverter using LAN cables to establish the connection to the local home network and the Internet.
• RS485/Modbus (RTU)
  Energy meters are connected to the Modbus interface and record the flow of energy within the house.
