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 ?
