[ARC5] 28 volt high-current supplies?

[Charles]

Looking for ideas on 24-28 volt supplies that won't break the bank. 
Shipping on big iron is REALLY expensive these days even if a suitably 
sized transformer can be found... Switching supplies from China aren't 
too bad. Two big batteries and a smaller charger to keep them up when 
not operating seems to be about the best compromise.

I'd like to be able to make 100 amps DC (which needs a 240 volt outlet, 
of course).

Any thoughts? thanks
