Hello
Does anyone know what happens if I make two ESS systems in parallel, on L1 or one on L1 and the other on L2 and set them to Total on all phases. In a three-phase system. The reason for this is two different battery banks, one with lead batteries and one with lithium.
Will they work together or will they discharge each other?
No, they need a common bank. Docs freely available:

You can have 2 separate ESS systems on diffrent phases with Different battery banks. You will need 2 GX's tho.
The next problem you will face is sharing the meter. This will require some custom software to work correctly, this can be done in the large version of the GX firmware using NodeRed relatively easily.
