I installed 3x 10kVa Victron Quatto's units on an installation, but not 3-phase synced (3 units run independantly on 48V battery banks). Requirement was not 3 phase synced, but rather 3 independant lines run separately. But client wants to be able to monitor all three units. I installed A single Venus GX, as the supplier confimed it can work. Is he correct?
