When Wallbe is turned off or power limited in PV mode, overcurrent detection is used to disable wallbe. Using overcurrent detection, Wallbe will go into error mode (state E). When EV is disconnected in this mode, Wallbox will remain in state E, thus not detecting car being disconnected (A).
Furthermore, since Connected() API will return true even in error state, polling of SoC will continue, potentially exhausting communication limit.

Solution is to switch from overcharge-limiting the Wallbe to using Dip 10 for enabling register-based control via modbus. See https://www.goingelectric.de/forum/viewtopic.php?f=34&t=13270&hilit=Register+Enable+Charging&start=20 for related discussion.
