Trying to replace a dead Schneider with a Victron system. Current wiring has AC IN and AC OUT of the dead inverter connected through a set of 60a breakers into the 200a residential panel (split phase 120/230) and it was set up to feed power to the grid in addition to taking some of the local load. Power source is 48v battery with dc coupled solar charging (non-victron). I understand I can use an autotransformer to convert a single 120vac or 230vac inverter into split 120/230 L1/N/L2 as needed to connect to the existing breakers/wiring. But I need to confirm a) that Victron inverters can be used to feed power to the grid (nothing to do with grid-tie from solar on AC OUT), b) what the wiring should be for this -- i.e. use the same set of breakers that connect AC IN & OUT, or do I only need to connect the multiplus/quattro AC IN to the grid and done.
So in essence, does the multiplus or quattro inverters have the ability to feed power synchronously to a grid over the AC IN connection -- will it work if I feed the inverter 48v DC and have it generate power to the grid over the AC IN connection only, or does AC OUT have to be tied to the grid in some way (which seems dangerous, and not sure why the Schneider was wired that way).
I understand that I will need to set up the inverter with ESS helpers for it to successfully feed power to the grid and take up some of the local load without having a 100a subpanel to run the loads through (I'm not going to rewire his panel). I'm just needing confirmation on selecting the correct inverter, and how to wire it, and confirmation that this is even possible. I'm preferring to use a single inverter and autotransformer rather than two inverter across the split due to cost, but if there are reasons to avoid the autotransformer for this situation let me know.
