I wouldn't be feeding the loads through the victron. Ie loads wouldn't be on ac out.It's not ESS but power assist. Are you looking at the Mp2 model? I just checked the spec sheet and looks like you're good as the 48/5000 Mp2 shows 95a transfer switch unlike the others that are only 50a. Also shows the aux output is 48a instead of 32a.
You can only have so much power come into and come out of the device.
I'll have the victron in parallel with the grid- victron would be pushing power to main panel via the ac input.
