Hello everybody, I have an issue updating the config of my MultiPlus-II. I would like to add ESS feature to the MultiPlus-II. But I get already some basic errors doing just download and upload. My system is new and is very basic. 1 x MultiPlus-II 48/5000/70-48 with firmware 552 1 x Gateway Cerbo GX MK2 wih firmware v3.52 2 x Pylontech battery BMS VRM instance 512 1 x EM24 grid energy meter firmware 1.8.3 Used Remote VEConfigure to download the MultiPlus-II 48/5000/70-50 (com.victronenergy.vebus.ttyS4) config file. Uploading the unchanged file again works. Just opening the config file with VEConfigure3 (Version 90.04.239 and saving the file without changing something results in the error mk2vsc-46. Do not know how to solve this. Some options are : 1. downgrading firmware MultiPlus-II 2. Buy a serial device for the upgrade 3. Keep searching in forums! Anybody any suggestions on what to do? Thanks, Hans ---

Issue is solved by playing around with several VE Config files. Think, but am not sure, that the (modified) uploaded filename should stay the same as the downloaded file! ---
