[RE-wrenches] Large lithium chargers

[Jay]

I got a call from a colleague that is designing a very large roughly 90-100 kWh lithium battery at 48v. 

He’s looking for large AC chargers to charge this bank. The reason is total elimination of switch over delay from inverter to generator and back. 

One technique is to use inverters for this, but pretty pricey. 

Any recommendations as to equipment, brands etc?  

It would be a 208 3 phase AC side powered by a generator. 

Thx
