Issues with Multiplus II GX Firmware v2.84 and ESS

Hello,

I'm using a Multiplus II 24/3000 GX with ESS in Mode 3.The device is controlled via modbus TCP from our own control system. I have updated the device up to latest firmware version v2.84 and sent the ESS settings via VEConfig. After that I always get a Modbus error and the ESS settings in the remote console are no longer displayed. Any ideas where the problem is?

Update the multiplus II to 494 Firmware - you currently have only updated the GX unit inside and not the inverter
