Understanding ECCO behaviour when switching on/off grid with AC coupling
I've got an on grid Ecco setup and an Ioniq 5 with V2L (a electric car that can act as an AC outlet). That V2L is 230v 50hz 16A, which is nice! It does not synchronis phase with the grid which stops it being V2G. Currently I plug the V2L into a mini consumer unit with seperate circuit in my house and run heavy loads like washing machine/drier off the car, it works great but is a little limited.
What I've seen some others do is plumb the V2L into the aux port of their inverter (configured as a microinverter) in an off grid setup. The Ecco can then sync to the V2L's AC phase and get the combined output of the car & their inveter. Sounds great. Would be somethign like this:
Downside is we can't charge the house batteries from the grid or top up power should we need more power than the two inverters can handle.
From what I understand if you just pointed the V2L inverter at the AUX port while connected to the grid it would be the wrong phase and AUX port would remain off but the V2L would keep doing its own thing indipendantly.
Is this assumption correct? (That the Sunsynk Ecco will just turn off the AUX port in this senario).
If I then lost the gird or isolated it in some other way the Sunsynk Ecco then automatically turns off the grid side, will it now automatically sync with the new AC source and turn on the AUX port (allowing the house batteries to charge and backup loads to get a boost).
Enquiring minds want to know! :)
