Any difference between RCT 2000VA and Mecer 2000VA Line Interactive UPS

Battery Capacity

Correct.

Its easier to do the battery calculations using Wh. Then you dont have to worry about 24V vs 12V. So if you have two 12V 9Ah batteries, whether they are in series or parallel, each can give 9A for 1 hour. 9A at 12V is 108W for 1 hour, so that is 108Wh. so if you have two of these, that will be a total capacity of 216Wh. And then if you want to prevent it discharging too much, you half it and get back to 108Wh. so if you appliances are using 100W of juice, you can run it safely for an hour (ignoring UPS efficiency, if someone can tell us roughly what that is then we can work it out even better)

Hope that helps
 
I know the RCT has a fan which already means it'll deal better with extending the battery or running for a longer time.

Not sure about the Mecer.

bought it and it has a fan :)
from all the descriptions i see on MYBB it looks like they pretty much the same unit with different branding.
Once i have the courage to open it up ill advise on the inside
 
Just buy the Mecer 1200VA invertor, 2 cables and a 105AH deep cycle battery (and plastic Addis bin to keep the battery tidily stowed in). Works like a champ. The invertor has built in charger and acts exactly like a UPS. I run 55" LED TV, ADSL router, 2 x9W led lamps, decoder, plus another router for 2hrs only using about 50% of the total battery charge. Takes the invertor about 12 hrs to fully recharge the battery when set to 10A charging (Mecer has selectable 10/20A charge switch).
I couldn't be happier. Plus the setup looks pretty cool with the Mecers blue fluorescent display panel.
Oh and the Mecer has 3 standard SA plug sockets built into the top panel as well. I know most ups's come with kettle plug outlets which requires you to mod a multiplug to use it for anything other than a pc.

Hey bud. What is the cost of your setup? Looking at getting the exact setup as you. Any help with prices and where i can get them will help.
 
Is this basic plug and play?

Have both. Has seen the inside of both. Exactly the same unit. Different face plate / branding but same unit.

Well prices are pretty much dependant on the cost of the main components ie. invertor & battery. The invertor is about R1500 (here's an example: http://m.bidorbuy.co.za/item/193826...h_LCD_Display_and_Socket_for_Solar_Power.html) and a 105AH deep cycle battery can be bought for about R1600 - R2500 depending on brand, model & where you buy it from. Plastic Addis box is about R80. I got my battery leads with the kit so not sure but probably costs about R100 or so. That's all you'll need. Drilled about 5 holes on each side of the Addis box near the top edge for ventilation. So about R3k - R3500 total cost.

Yep, nothing to setup or configure. You connect the battery to the invertor using the battery leads, plug the invertor power plug into a wall socket, push the power button on the front panel of the invertor, and and it will start to charge the battery. Plug your load (TV/lights/multiplug) into the invertor output power sockets and your ready for load shedding.

Thanks for the help bud. Will look into this during the week.
 
Guys, This may sound dumb but I have limited knowledge in this department. I searched for info but could not find anything. Can this device work off 1 battery? if not why?
 
isie said:
depends whats the voltage.
if 12V one battery if 24V 2 batteries and so on.

Ok makes sense now. I basically need a ups/inverter to power my lcd tv, dstv and adsl modem for 2 hours during loadshedding. So whats will suit my needs?

What's you budget and I just need the wattage of the devices.
My rough calculations - I am probably over estimating
LCD TV - 100W
DSTV - 80W
ADLS - 20W
Total 200W=
At 24 V - 9 Amps
At 12 V - 17 Amps
If you buying the UPS i mentioned in my OP it's a 24V with a 9AH Battery - you will only barely get an hour out of it (30 minutes to be safe)
On Samans suggestion thats a 12V on 105AH Battery +/- 6 Hours - (3 Hours to be safe)

My to be safe is you don't want the batteries to be drained more than 50%

Ok, will check my devices and let you know. I'm just trying to avoid buying 2 x 105ah battery if I don't really need that much. If its going to benefit me in the long run with running other devices then I don't mind.

If you only using for the things you mentioned maybe this:
300W Inverter + 102Ah Battery Kit
Its not very Big and should suit your needs?

Prices isn't Bad just R245 Delivery is a bit steep (but considering what it weighs :whistle: )

I actually got about 3 Hours out of mine - Stock Standard - unfortunately load shedding in my area then goes into fault at substation so lasts longer than 4 hours - so had to upgrade.

On the RCT or the Mecer?

My old UPS has shot batteries and doesn't support USB (to turn the bloody alarm off) so I figured I might as well buy a new one.

All I want to run on it is 2 x Routers + HP Microserver and possibly a long LED strip light in the future.

So if a 55-inch TV runs for 2 hours I should be good to go.
