The Xantrex isnít a Hybrid inverter like the Victron if that matters to you. It wonít supplement an external power source, like a small generator, with battery power.
More to the point, Iíve had issues in the past with the current requirements of big inverters with the stock batteries. You may find the voltage sags excessively. That may force you down the Lithium rabbit hole if it doesnít work out. AGMís might work or two parallel 12v
batteries. Also be aware the cables from the battery to the battery may need to be upgraded.
Xantrex is a quality company so I would imagine that inverter is fine as far as that goes.
