I am considering 2 MultiPlus-II 12/3000/120-50 2x120V models. I need to support 5.5kw 220 at 29amp and am not sure if a transformer is necessary (https://www.victronenergy.com/upload/documents/Datasheet-Autotransformer-32A-and-100A-EN.pdf) or if I could stack the two 120v inverters to support both 120 and 220 loads simultaneously . Your advice is greatly appreciated,
Superbedankt!
