EVCC begrenzt den Strom nicht auf den zulässigen Maximalwert, daher bitte den maximalen Strom in EVCC entsprechend konfigurieren.

- Bernecker Engineering MPM3PM (template: mpm3pm) with ID 5 or ID 6 for the Duo's second connector.

- Be aware of the limitations of the openWB SE HW regarding maximum allowed currents, see https://wiki.openwb.de/doku.php?id=openwb:technische-daten:openwb_se.
EVCC does not limit the current to the allowed maximum, so please configure the maximum current in EVCC accordingly.
