Powering LED TV during load shedding

That should be built into the inverter, I'd be very surprised if not.
So my initial estimate was actually right, just hit 100% from 50% draw down. So that was 2 days an 10 hours. Voltage will be 13.4V and currently reading 13.3V so may have a little to go still.
Would something like this help to speed up the charging time?

I bought 1 like this (Auto Gear branded) to charge my bike battery after I had not used it for 3 months.

A bit more expensive: But the RCT 3000GT has ports for external batteries.
It comes standard with 6X 12V/9Ah batteries, however it has an 8A charger and external port for batteries.
Take note though that that battery pack runs at 72VDC (Charging @ 82.1VDC)
EDIT: For reference:
RCT1000: 2X 12V/9Ah : 24VDC
RCT2000: 4X 12V/9Ah : 48VDC
RCT3000: 6X 12V/9Ah : 72VDC

And if you live in a flat?
It should, just not 100% what happens when you have 2 chargers on the same battery.

Read the spec sheet for both and see for yourself.

Guys, why reinvent the wheel? They've been selling suitable Inverter/Battery Units for years already. Many co-ops and Electronic suppliers have them. Even Tedelex were selling one. Usually they consist of a fully automatic Unit that will switch over to standby without a hick-up and then charge the battery as soon as the power comes back on. They come in wooden boxes on wheels and two sizes, 1kva with one 100AH battery or a 2kva with two 100AH batteries. Prices these days around R6 000 and R8 500 respectively. When calculating power requirements for a TV, don't forget the decoder which takes more than the TV does. I did one myself a couple of years ago, consisting of an Omni-M1000 Auto inverter, think I got it at Sinetech in Kent in Randburg, hooked up to 2 100AH batteries, same thing essentially. It runs the TV combination, couple of lights, my laptop and cells etc. for somewhere around 10 hours. Takes about the same time to recharge the batteries again. Easy enough to get more time by just adding batteries. Got a 2kva recently and will wire it into my DB with a change over switch on selected circuit breakers. By the way I've got it backed up with a generator (outside) to keep it all going indefinitely. We had a 4 day power outage last month and that at least kept all the Comms going.

Looking at the specs from this site:
http://www.voltronicpower.com/oCart2/index.php?route=product/product&path=37&product_id=52
looks like the only main difference (besides the LED's) is the maximum load they can handle.
I think I'm gonna go with the 1000VA model, as I just wanna power my LCD tv and USB powered drive, as well as 2 x 10w LED bulbs.
I'm glad I bought myself a 2 plate gas stove and 9kg gas bottle.

Spec sheet doest say what size current charger is built in . So better find that out before you doing battery mods. But of course its built in with up to 9Ah batteries which take 4-6 hours to charge to 90% , imagine charging a 100Ah to 90% ? how long would that take ? 2-3 days ?
Also Price?

Yeah that is something to consider as well. The 1000VA is R892 at Takealot and the 2000VA is R1499 so that's a difference of R600.

Kind of off-topic here, but I have an RCT2000 (rated as 1200W) powering a Samsung Plasma TV (2011/12 model), and an AVR. The TV is said to draw 300W and the AVR a max of 600W.
One thing I noticed over the weekend, is when the load shedding began, the AVR remained on perfectly but the TV turned off and then on again. This is bad for a plasma TV when this on-off happens (I was told by a plasma-repair shop), so is there anyway short of buying a different UPS to solve this?

Does the tv do that if the AVR is off when it switches to battery power?

Haven't tried it, but will see if I can replicate the problem, then check what it does with the AVR off...

It takes 10-14ms to change over on UPS I think, not really much you can do about that. If TV cant handle it you're stuck, because I dont think you're going to get a much better switch over time.
