Using BMS to disconnect ac supply from Multiplus using a relay

Is it possible to just use a relay to cut off ac consumer circuits exiting from the Multiplus inverter. As in a low voltage/soc situation. Seems cheaper than a giant contactor to cut dc supply to inverter. Am I missing something? Just looking at simple bms at the moment with no can bus comms. Or can I use simple relay to change mode remotely?

The inverter already has a low soc and low voltage cut off that is programmable.

And an ac out that is programmable for load soc conditions.

There is a two signal bms assistant as well. A few threads on the forum dicuss it's uses in controlling the inverter. So the product is already capable.
