At home I have 3 MPs+EM540 and 1x Wallbox+EM340. Both have separate RS-485 bus. The ESS is enabled for battery of 16kWh with sun energy (PV inverters)
I have discovered that the Wallbox EV charger with dynamic load balancing will not charge my EV when there is enough sun energy. Meanwhile the battery is being charged with sun energy. So the Wallbox is too late to get green energy. It will stay at 0 kW power consumption.
If I have disabled the battery charging by setting menu Multiplus->Switch from 'On' to 'Inverter', then the Wallbox is able to get green energy.
It is related to a reaction time of both systems ESS and Wallbox. ESS is very fast with trying to achieve 0W on the grid. Is there a better solution to make Wallbox as highest priority?
