Clariion FC4500 PSU Voltage Q

[lesconnally]

I think I understnad, but on the Clariion FC4500 Battery PSU, the OUTPUTs (?) say 220 V and /!\ so I am supossing the /!\ next to the INPUTs is also 220 V.. er.. yes? They tried to be visual but just made it all vague and non-specific.

So, to run it on 110, I just cant use the PSU battery component, correct ? (there are always USPs available.)

Ok, the PSU is actually caled a SPS

Standby Power Supply, although what it is, is a UPS (uninterruptable power supply)

The SPS has a input of 100-240V, and output of 220V

Although with most SPS's the actual Management portions of the UPS dont function with a 110V input. i.e. The Array wont be able to communicate with the SPS. Without this communication, the Array doesn't actually know it's plugged in to a UPS, and therefore will not allow you to enable Write Cache.... Write Cache is nice

But, in a worse case scenario, (i.e. home residence) where 220V is not an option, you can use a pair of SPS's to power your array with a 110V input.
