Using the inverter as a 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.

The WLAN bridge is activated automatically when the inverter is working as a WLAN client and is connected to a WLAN gateway, a LAN cable on the inverter is plugged into other devices and the Automatically acquire IPv4 address function has been activated under the LAN interface.

INFO

WLAN bridge cannot be activated

The WLAN bridge can only be activated automatically if no other DHCP server is detected in the network. All other devices may only be connected via a LAN connection to the inverter, which serves as a WLAN bridge.

This means that no device that is connected via LAN to another router/gateway and obtains its network data via another DHCP server may be connected to the inverter that is to be used as the WLAN bridge.

Connecting other devices to the WLAN bridge

DANGER

Risk of death due to electrical shock and discharge!

• De-energise device and secure against being switched on again.

INFO

A Category 5 Ethernet cable (Cat 5e, FTP) or better with a max. length of 100 m is required to connect other devices.

1. Switch the DC switch on the inverter to OFF.
2. De-energise the inverter and secure it against being switched back on.
3. Guide the Ethernet cable into the inverter.
4. Seal with sealing ring and union nut. Tighten union nut to the prescribed torque. Tightening torque: 8 Nm (M25).
5. Connect the Ethernet cable to the LAN interface of the external device, e.g. inverter, energy meter or battery.
6. Connect other devices via Ethernet cable.

1. The external devices are connected. After initial commissioning, the WLAN interface still has to be configured in the inverter.
