Running a Nano on a UPS

[yeldarbj]

Roger,

I am looking into getting a UPS battery backup as hurricane season approaches. I want to run a Tunze Nano 6045 on the UPS, nothing else, just to provide emergency flow until the weather settles enough to get out the generator. I think with the low power draw of the nano, I should get many hours of run time from a decent sized UPS (~400-500W). From what I've read, people recommend using a UPS that generates a true sine wave output to run pumps. Does the Tunze Nano require a true sine wave or will it work just fine on a modified sine wave?

Thanks

Good question, tagging along.

I found this thread where it is discussed somewhat, even someone saying that a Nano did not run on a UPS, but doesn't state what UPS. I would like Roger's input on this. Seems like the UPS's produce square waves, modified square/sine waves, or true sine waves, depending on how high end the UPS is.

For the Nano it is very critical that the power be a clean sine wave and a steady 100-130V. I would expect it would run otherwise but may chatter periodically and start backwards. The 6055, 6000 and 6100 do not need the clean sine wave as they are DC.

Thanks. That's exactly what I needed to know.

So using this http://www.xantrex.com/web/id/22/p/66/pt/8/product.asp

with a big deep cycle battery would not be ideal???
I have one

Well I just tried it and my 6025 would not start on the inverter with a fully charged battery. I think I'm going to bite the bullet and buy one of these: http://www.refurbups.com/APC-Smart-UPS-1400-Black
which has a true sine-wave. A small investment, I would rather have generator but I can't.

Since you already have the deep cycle battery, you could probably find a true sine wave inverter for it. Like this:

I think the deep cycle battery will last a lot longer than what you get in most UPS's.

Have you tried running any other pumps/powerheads on your current inverter?

Thanks man, I should have looked into that. Sounds like a better idea.

I had 2 x 6045 and 2 x 6025 running on my UPS model 150 I think, there was no problem.
