I don't think so.

You could have a complete parallel DC system in the house
powering lights ?, special DC immersion heater and then an
inverter for local 230VAC stuff but not mains connected.

That or a meaty UPS setup of some sort.

This defeats the main purpose of domestic PV panels though which is
to milk the subsidies and you need to be on the grid to do that.

They either are more stupid than they seem or its just cost cutting.
