I have experienced a problem with a customer's ESS system. Multiplus and Fronius inverters are connected in parallel to the grid. There is a TOPzS batteries installed. ET112 meter and BMV700 is installed too.

I called my Victron Seller in order to request them to write to level3support mail. But I have no news and no technical explanations.
