    Hi, I have a server room with 6 24x7 running servers, and 3 switches, 2 routers and 1 server rack monitor.

    So, what kind of backup do I need ?

    I was thinking to get a 1400VA sinewave inverter and 4 batteries, 180Amp each.
    And then power it with 2 solar panels, 300W each.

    Is it enough to serve the server room for like 20-24 hours ?

    I would go with a UPS for each server and maybe 1 or 2 for the switches, routers and monitor. That way you're not relying on just one UPS to do all the heavy lifting in a power outage. If one UPS + server gets shutdown, you can rely on the other UPS's to power the servers.

    It all depends on how much $$$ you want to spend and how much up time you want.

    You mean one UPS for each server ?
    Each server has 2 cables, means 2 PSU.
    What kind of power and UPS would it required to serve for 15 hours or so.

    Yeah, one UPS per server. You could hook up one of the PSUs to a UPS and the other to mains. The two PSUs in the server is for redundancy; if one fails the other will still keep it on.

    Have a look at the specs of the PSUs in the servers. Should try to get a UPS equal to or greater than the PSU. For it to run for 15+ hours, a butt load of batteries.
