Is there not one software that can be used to set-up the Multplus 2 using a Cerbo GX? This has become a nightmare.
It’s a basic installation to charge batteries and the supplement the utility power when I decide then recharge the batteries at night.
You can program through VRM if your Cerbo is connected to the internet. There’s lots of talk out there on it. Its also in the MP manual. Its a little more complicated than just plugging in a MK3 and using VictronConnect but can be done.
