Where does one get one of these cabinets? Got a 2 year old with a sense of adventure!

Don't quote me on 2 batteries. The smaller one looks to have room for one battery.

The ones on site are different. You can email them for a quote loveness@cps-africa.com

Got about 4 hours in evening after it was running whole day (18w for internet only) and then 1x50" tv, 2x 23" monitors and desktop (350w total). Get over 6-8 hours with computer and 2x screens.

Do you know what % your battery was at after all that? Are you trying to avoid discharging below a certain point?

Nope, no interface. Look APC if you want stats with a UPS. I run flat when needed(not too often but just to test cause its new)

Nope, just the unit itself makes a bit of buzzing. Pure sine wave



Its the kind of unit you plug TV's/random stuff into that you want on always. Worst case you could run a genny 12h per day for charging and 12h on battery

Thanks, what Deep Cycle battery and inverter brands are you using?

Looking at a Deltec Varta 105 Ah battery, not sure for inverter.

Will get an 8A charger, which should enough to charge in 20 hours by the next loadshed (Stage 2 and 3 becomes more tricky though lol).

Pricing on that Deltec Varta 105Ah..?

You guys realise those RCT's are only going to power you for max 30 mins right. So you're looking for a shutdown solution not a bridging one.

There's lots of talk about chucking a battery on them, but the charger will need alot more than 24 hours to fully charge a battery big enough to bridge the 2-3 hours for a load shed.

Bought a RCT 2000VA on Takealot. I can confirm the following: It comes with 2 x 12v 9ah batteries. They are connected in series and NOT parralel. This is to give 24V needed to run this size of an UPS. I also picked up 2 x 105ah 12v deep cycle batteries at Echo 4x4 centre on Durban Rd, Durbanville for R1500 each. I've chucked out the old batteries and added the new deep cycle batteries to the ups in series. Batteries was on 65% at 11:45, at 17:15 they were charged to 85% by the ups alone!

Its able to power 3 x HP mikroservers, i7 Laptop, VDSL router, 2 x Mikrotik SXT's , RB-951, RB-911, RB-912, 50" led tv, DSTV explora, Xbox one and a few energy saving lamps without a hitch so far...

I will report back how long it can run these things for on battery when load shedding finally happens again :p

From the review section:

Very happy with this UPS. I am using it to keep my ADSL Modem, A 23" LCD screen and a landline online . So far it works great and has lasted through the load shedding. It has a few bonuses like ethernet and phone line surge protection. The software is quite nice and gives a good view of what is happening to the UPS. I even tested it out on a DSTV decoder and a 55" LCD tv and it lasted really well.

Yeah, I have one sitting right next to me attached to my work PC. So I've tested first hand (650VAC), that lasts about 30mins. The 2000VAC does have slightly more battery capacity though and because its 2 batteries vs 1 battery that also has a positive effect.

That guy in the review is only running a monitor and modem - will be a low draw. The 55" wont last 2 hours though, you're looking at 140-160W there.

Well I'd have to test this for myself, but the maths doesn't work out.

Based on the 6 hour charge to 90% of the standard unit (RCT2000VAC) it suggest a 2 to 3 Amp Charger, which shouldn't be enough to load 2x105Ah batteries in 22 hours.

But hey, !@#^ the math, if it works, it works.

Check the rest of the thread, you'll see some more reports of run time and loads it can handle.
The charging rate of the internal batteries cannot be used to determine the rate for the larger external ones as you do not know the control mechanism used on the charging circuit.

The RCT2000 uses two batteries in a 24V config, so it changes things a bit. Lower current for the same power output.

And the RCT2000 is OUT OF STOCK again...

lol, This is how electrical fires start.

I'll give it a try and see, at the end of the day I don't get load shed anyway haha, 'Touch Wood'. I'm helping my mates in the less fortunate areas.
