The inverter in question is the one being utilized in conjunction with 
the powerwall, ats, solar array. All nicely done and reliable and wired 
in already and with proper capacity.

Being able to call for and get more DC power on demand would make this a 
true uninterruptible solution.

Running a gen to support the battery means the gen size does not need to 
correlate at all with the peaks and surges of demand and can run at 
maximum efficiency and we can avoid unbalanced leg problems and other 
voltage variation issues that can happen with portable gens.

Programming comes into play for automated monthly testing, capacity 
prediction, even spot costing of utility power. Between the grid, the 
solar array, time of day, season, weather, battery level, generator 
input, load characteristics, outage duration, grid costs/stresses there 
can be a lot of factors that might need a bit more balancing and 
programming than you might typically expect available from any half 
decent battery inverter, but might find a nice place in a truly fully 
integrated home UPS solution.

Integrate it enough and perhaps the gen/rectifier components would even 
fit into typical residential facilities spaces and this sort of setup 
could be all the more typical and standard.
