My setup is as follows on-grid:
Victron Quattro 48V 10KVA 120V, (two AC -IN, two AC out, one for critical load and another without it breaking power when power fails) the inverter is using a Victron AutoTransformer 32A feeding house's main panel split phase L1/L2 with 120V each leg, also I have a grid tied inverter Fronius Primo 6.0 with 7Kw Solar panels on the roof. When the grid fails Victron inverter engages providing power , but I loose the power provided from fronius solar panels which is disconnected from the grid.
What is the proper wiring in order to use AC coupled option with Fronius Victron Transformer harnessing the solar roof power.
Thanks in advance.
