Powering LED TV during load shedding

[viceroy]

I have an Ellies 2kVA (1.2kW) 24v modified sinewave battery backup system.
Bought it from Builders Express in December 2014 for R6500.
Runs my Samsung 46" LED smart TV, Xbox One, AV Receiver, Sub-woofer, speakers, DSL and a few lights for about 6 hours.
Can also run my PC with the above setup but then duration drops to about 4 hours.

Switch over is seemless and no issues with it being modified sinewave.

Ok, so I can confirm that The RCT 650 VA UPS with a 100Ah battery attached is definitely enough to power TV and DSTV. I ran it for 4 hours and used 30% of the battery, now I'm testing the part I'm skeptical about, the charging.

I have a 46" Samsung 5 Series and a PVR Dual view decoder.

Cost of the setup was about R2000:
Battery (Stride Deep Cycle 100Ah from www.Solarsolved.co.za) - R1254
UPS (RCT 650VA/360W from www.Takealot.com) - R482
Cables (2m of 5 Gauge from Sound Match) - R100
Lugs, nuts and bolts (also from Sound Match) - R30
Power Cable (Same cable that goes into PC Power Supply) - R80

They don't include the Power cable with the UPS, so you need to get it somewhere else. Unless you're planning on putting it inline with your PC then you can use your current cable because it has 2 male to female PC Power Supply cables and 2 female docks on the back of the unit.

Hi Shard
Saw your setup above and it looks ideal for me a pensioner who is looking for a less expensive fix. I only want to run a 42" (160W) TV for about 2 1/2 hours every 48hrs.
Did you connect the 100 AH battery in series with the installed UPS battery, or did you replace the original battery with the 100AH battery? A sketch or explanation of your wiring setup would be greatly appreciated!!

You must replace the original battery.

You must replace the original battery.

Thanks Mike, for confirming this.

Instead of modding the UPS with bigger batteries, thus losing the warranty. Just buy the complete system.
An 2000VA ups = +/- R1400. 102AH battery = +/- R1600 (and you need 2 for 24vdc). Maybe add in R300 for the wiring and connections and more R's for battery boxes. Instead just buy the complete sets with everything for something like R6k+.
Obviously its for the "modified sinewave" sets. The pure sinewave will be more expensive.
And it will run for more than 4 hours depending on load.
www.geewiz.co.za has some nice prices for it.

Just my two cents

I recently purchased a new pure sine wave inverter, 600W and 30A charger, with a load display (handy) + 1 Dixon 105Ah battery for R3,600.

Got this specifically for my bedroom 42", soundbar, wifi, Roku and switch.
Powers this setup through a 3.5 hour shed with ease.

Very pricey actually.
Bought individually it works out to R2800 and that's retail prices.

Wow. Thats a lot cheaper ! And that's for 2x 102ah batteries + 2000va ups + extras ?

 

[kahoel117]

With these UPS systems, can one connect it to an solar panel + charge controller ? To charge the batteries atleast instead of being charged by the UPS. I take it, it would still cost some money just to charge the batteries to its original state from Eskom power.

Where do you get those prices?

What charger for 100+ah?

Most of the newest modified sinewave converters do not cause any visual interference like snow/static anymore. It does however cause resonance in the power unit of the TV, leading to a buzzing sound. I normally use a wireless headphone connected to my amp, so this does not bother me. Without the headset the buzz is audible, but it does not take long before you do "not hear it anymore".

I have a 1000W Modified Sinewave Inverter and a 100Ah deep cycle battery and it runs my 48" plasma, WD TV Live, DSTV decoder and Amp for 3 hours easily.

Also had to buy a charger, electrical cables etc. All in: R 4 500

I turn everything off few minutes before load shedding starts. Plug my multi plug with all my media stuff into lead going to inverter and turn everything on again. When power comes on I turn it off and immediately put the battery on charge.

Hope this helps.

Hi there,

what charger do you use? I want to do something similar but not sure about the charger.. Will a normal car battery charger work or would one rather go for something like this: http://optimate-battery-charger.co.za/shop/accumate-pro-12v-24v/ ?

I would really like to keep the costs down and this charger is quite expensive..

Thanks!
