There was some discussion here maybe a year ago about similar things. Try 'inverter, whole-house, room, circuit' - those kinds of things were discussed. Someone had some brand recommendations.
You mean this thread? http://article.gmane.org/gmane.org.user-groups.linux.gnhlug/1307 That was mainly about surge protectors. It never got into UPSes, other than to say "UPSes are good to have, too".
I seem to remember someone saying the efficiency of the always-inverting type was very poor, increasing heat and power costs noticeably.
You definitely take an efficiency hit. However, in this case (extremely dirty power and extremely expensive and sensitive equipment), I believe we don't have much choice. We need something that can handle frequent severe sags as well as all sorts of distortions. A stand-by UPS will be tripping on and off battery all day long, and be dead within a month or two. That's inefficient, too. :-) -- Ben _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
