I have a CentOS-5.6 remote server in a house in Italy, where there are occasional thunder-storms. There was one yesterday, when the electricity went off 3 times, for a second or so on each occasion. My server, an HP MicroServer, came back (re-booted) on 2 of the 3 occasions, but not on the third. I assume that the problem arises because the machine does not close down properly. (Although it is

...are not designed to be run 24/7, this one is. * Two 12V 200Ah Renology AGM deep cycle batteries wired in parallel. Got a deal on these. I decided I was ok with 75%-80% DoD even though these are lead acid. This gives me about 3.5kWh of usable AC capacity. * Batteries and charger are wired up with 4AWG, the inverter is something smaller, I think 6AWG? What I have built is a double conversion online system. The inverter is powering the AC load all the time. There's no transfer switch. There's lower efficiency when power is on because the normal power path is always AC->DC->AC. I di...
