Wow!  That is a lot of current. I guess you are looking at a car 
battery?  You are going to have to use some very big x-section 
conductors to avoid loosing too much power. A better option would be 
to aim for 24V -at- 200A or even 48V -at- 100A. The TC itself is no problem. 
Just look for any designs around running at 4.8kW. The inverter will 
need careful attention to avoid smoking some expensive silicon. 
Sorry, no design off the cuff for that power supply. Apologies.

Malcolm
