Why sure you can.. just that the wiring (no doubt measured in cmil, not 
AWG) alone from battery to inverter will weigh more than the rest of the 
entire shack. (let's see, probably something like 16kW from the battery, so 
it's only a bit more than 1000 Amps.. probably need some of those really 
big Anderson PowerPoles as connectors.. make sure you carry that big wrench 
for tightening the bolts)

But realistically, if you're using a switching power supply (which should 
be the trend of the future for HV power supplies), 12VDC in or 340VDC, all 
that really changes is the efficiency (and the weight of the primary windings).
