Larry. I have used a 600 VAC transfer switch from Sq. D I never had needed for 
it to be DC; however the insides are similar to the 600 VAC-VDC, it snaps open 
and snaps closed in both positions.  I will ask my SQ D supplier, he is usually 
good. 
 
BTW Nice idea, thanks.

With 4800 watts and HV input, it seems to me that a simple battery backup can 
be formed from an existing PV grid tie system. Block diagram attached. Where 
can one find a 600 volt rated DC transfer switch?
