recommendations for home UPS...use for AV?

[ShaQ.Blogs]

We are exploring the option of getting a ups for entire home.

1. Can I connect my amplifier and plasma tv to the home ups...or do I need a different kind of ups for such equipments?
2. Are home ups reliable/recommended for sensitive AV equipments?
3. Any specific model/type that I should explode? We were looking at sukam.
4. What ups rating should I go with?

Peak load could be like,
(a). 4 fans, 8 cfl light, 1crt, 1 wireless modem, 1 set top box, 2 desktop pc's. (About 1000W)
(b). 1 receiver, 1 plasma tv, 1amplifier (500W to 800W? )

Considering the power requirements of (b), I am thinking of not connecting them to the home ups, but connect to a 15 amps line and continue using it with my current 1.5kv backup apc ups. So if power, I need to switch them off.

I will be interested in following this thread too. What I believe that stuff like AV equipments, including desktops & laptops, and fans should ideally be fed with sine wave. Look for sine wave inverters to start with. What I know, Sukam is among the best. APC should be the best.

My setup has a sukam 800va ups for the top floor with backup power to most sockets, fans and lights...

I ve connected my ht setup to a 2kva ups, which is connected to a socket having ups backup..

However since the load of the ht setup is low, (less than 10% capacity of stabilizer, as shown in stabilizer display), and since the other load is low, just one or two fans and two led lights, am able to run the ht setup in backup power without any problems.

Regarding ups, go for pure sine wave ups. Sukam should be fine.

Not sure about wattage though.

P. S: it is said to avoid running ht setup in ups power, in multiple threads here and elsewhere. I don't know the reason, but i try to avoid when i can...

Hope that helps.

I have been running all my AV gear on Online UPS for the last one month, I haven't found any difference but that's me.

Bump....anyone?

Understand that your ordinary household load can easily be powered by an inverter that costs significantly less than an online UPS which gives a pure sine wave signal, so consider if you can invest in two units one for expensive sensitive equipment and another for fans lights TV etc. I have two units, and APC online UPS and a Sukam inverter.

George, does that mean the so called sine wave inverters do not give pure sine wave output??

+1.
I had the same Q. I read in some threads here where sinewave inverters from sukam was recommended.
What's the difference?

There is a difference between online and offline, the former is more sophisticated and considerably more expensive than the latter(most home inverters are the latter). Generally the online ones certainly the better ones give you sine wave, which is coming through the batteries and is clean power. I see that Sukam claims they have different products with differing specs worth checking which is which before you buy.

If I could refresh my long forgotten graduation subjects, only the ideal transformers (theoretical) could replicate the same input wave forms, identically in their outputs.

Even if the input is fed with a perfect square-wave, the output will not be a perfect square-wave mainly due to (infinite) harmonics, inductive behavior,magnetic reluctance etc etc and solely depends on the characteristics of the particular transformer.

Matter of fact, even the so called Square-Wave is not perfect, and is distorted and expected to follow the Fourier series. The below gif explains how distorted the square wave is... No wonder Deep Purple made that album Nobody's Perfect
