I dont know about the grid tie capabilities, but it cannot supplement with battery power.
What I do know the LV6548 does (and I don't know why the LVX6048 wouldnt) is if you have it in line mode (where it is bypassing from the grid) it will supplement with PV power, so if you are drawing 8kw of power, and you have 4kw of PV available, it will put in 4kw of PV and 4kw from the Grid. But it won't do it from the battery.
Also keep in mind these units cannot bypass a ton of power. If I remember correctly it is only 40amps they can bypass. Keep that in mind.
