EM24 RS485 on 120/240V split phase loses its settings

We set the EM24 meter to mode E (application E?), split phase 120/240V. ESS mode operates fine (i.e. the inverters feed power upstream without feeding power into the grid), but the meter loses its settings, but after a few seconds, it looks as if the Venus changes the settings of the EM24 to three phase and the system starts to behave erratically.

Let me rephrase the question. It seems that the Venus is changing the settings of the EM24. What happens if we disconnect the transmit line between the Venus and the EM24?

Better yet, what do we need to do in order to have en EM24 with RS485 operate on an ESS system?
