MENNEKES AMTRON® 4You 300

The brand new charging station AMTRON® 4You 300 uses Modbus RTU to interact with the Loxone system (Loxone Modbus RTU extension needed).

Here you can find further information about the supported AMTRON® charging stations:

- AMTRON® 4You 300

Please be sure to have the latest software update installed on your wallbox:

- use the MENNEKES configuration cable together with the latest version of the MENNEKES configuration tool (v2.2) - supported version of the wallbox software for the charging station: at least v2.0 (03/2024), current version v2.2 (07/2025)

To use the charging station as a solar controlled modbus satellite, set the DIPs 4,5 and 7 of bank S1 to "ON" and restart the wallbox.

For dynamic phase switch (automatic switch between 1- and 3-phase charging) it is necessary to have the option "dynamic phase switch" activated via the MENNEKES configuration tool (https://www.mennekes.de/emobility/produkt-details/mennekes-konfigurationskabel-18625/).

MENNEKES Modbus RTU uses the following communication parameters per default:

- Baudrate 57600 bit/s - 8 Data bits - 2 Stop bits - modbus address of the wallbox: 50 - It is also possible to adjust the Modbus settings regarding your needs (baudrate, data format, modbus address). - >>> For more details regarding the modbus specification: check the attached description.

The minimal registers needed to control your AMTRON® 4You 300 are:

- Heartbeat: 21930 (cyclic, at least every 10s) - Charging Current: 6...16/32A - Charging Release: 0=prevent charging, 1=allow charging

You can also use the attached template including the usage of the phase switching option for the AMTRON® with 11kW. Just replace the "PV Power" with your own live value.
