I am wondering what you guys are trying to run on an UPS and why.
Here is my thinking.
For a 1-8 hour power outage all it seems you really need to care about is circulation. In my 150 I tackle that two ways - 2 penn plax battery operated air pumps that come on automatically when the power goes out and a mj 1200 on a mvt wavemaker on a small UPS. The air pumps will actually run for 2-4 days before the batteries run out, and are sufficient to keep the tank in O2 and circulation. The mj on the wavemaker and UPS will run for at least 8 hours as well. The combo is cheap and more than enough for your usual california power outage - heat is generally fine, and a tank can go for days without lighting. If there is a bigger outage either I won't care about the tank because something very bad happened or I can fire up the inverter or the used generator I have, both of which give me power for other things in the house as well.
I guess what I am getting at is, although neat, I am not sure what the recent draw to big UPS's is. If I were going to spend money on backup, I would be looking at just circulation and it seems the best bang for that buck might be a vortech with the 30 hour back up battery that needs nothing special in the way of maintainance except for sending it back for inexpensive, ecologicaly sound replacement every 5 years.
Why are people going with big UPS's?
