New repeater WS-12-250-DC ?

[jg0007]

Hello I am planning to mount a repeater with 8 rocket ac PRISM an airfiber 5X

All this connected to a WS-12-250-DC unit


I need to calculate my battery bank for about 2 days of work assuming I do not have solar power for 2 days could they help me at that point


So far I have thought working with a bank of 24V DC

According to the question, what would be your recommendation, Amps, voltage?
