Dynamic Load management –
Stand-alone mode (DLM)
The TurboConnect Charge Station has a local, dynamic load
management stand-alone function. Here, one smart meter
per Charge station is connected to the wall box via a router or
DHCP switch.
This communication makes use of the Modbus TCP protocol
via the RJ45 port. A connection between the wall box and
router can also be made using Wi-Fi, but this setup is not
recommended when using a smart meter on account of the
potentially unstable connection.
A list of compatible smart meters can be found at
https://www.evsolutions.com/ev-charging-product-resources.
The DLM communication protocol for the TurboConnect
Charge Station can be enabled in the Setup app
https://www.evsolutions.com/ev-charging-product-resources or
via the integrated WebUI chapter 8, "WebUI" on page 16.
Alternatively, the TurboConnect Charge Station can be
connected to the smart meter directly using an Ethernet cable.
However, this type of connection is not recommended as both
devices require a static IP address.
NOTE
Assign a static IP address to all Webasto TurboConnect
Charge Stations using the settings on your Internet
router.
Webasto TurboConnect
There are two possible locations for the smart meter in the house:
1. Smart meter is located at the hub of the central electricity
grid panel.
2. Smart meter is located after Charge Station in the dedicated
circuit.

Home Energy Management System
(HEMS)
The TurboConnect Charge Station can be integrated into a
range of energy management systems (EMS). Here, the external
EMS module is connected to the wall box via a router or DHCP
switch. This communication makes use of the Modbus TCP
protocol via the RJ45 port. A connection between the wall box
and router can also be made using Wi-Fi, but this setup is not
recommended when using an EMS system on account of the
potentially unstable connection.
A list of compatible EMS modules can be found at
https://www.evsolutions.com/ev-charging-product-resources.
Depending on the EMS selected, functions such as
photovoltaics (PV) excess charge or dynamic load management
with multiple wall boxes (cluster) are possible. The EMS
communication protocol for the Webasto TurboConnect
Charge Station can be enabled in the Setup app
https://www.evsolutions.com/ev-charging-product-resources or
via the integrated WebUI chapter 8, "WebUI" on page 16.
Alternatively, the TurboConnect Charge Station can be
connected to the EMS module directly using an Ethernet cable.
However, this type of connection is not recommended as both
devices require a static IP address.
NOTE
Assign a static IP address to all Webasto TurboConnect
Charge Stations using the settings on your Internet
router.
