DC power system -48V Help needed.

[Smart]

Rectifier and inverter design configuration to serve AC and DC loads. The system is to have a -48 V DC battery string that will be connected to a -48 V DC Power Plant with rectifiers. From the power plant an inverter system will be connected that will serve the AC load. The 120/208 Volt AC power supply will be connected to the DC power plant that will serve to charge the battery string. During an outage, the battery string will be able to support both the AC and DC loads.

The AC load is 80.87 kVA and DC loads is 14.65 kW. Sizing of the rectifier & inverter modules is necessary. How do I determine the rectifier and inverter size. Is there any layout design and/or electrical configuration that shows the wiring of the units?

Interesting set up, what will it be supplying? This is not a set up I have come across before.
