UPS or ??? (Load Shedding) Solution.

[Mr L]

Hi guys,

So I know we all love load Shedding and we all want to live in the dark but my wife is not a fan, who knew🤣

Okey joking aside, my wife needs to be able to use her computer during load Shedding but I'm not sure if a UPS or generator is the best solution. I'm not sure if a generator is good for a PC. (Not sure if this is clean energy, if that makes sense🤔Have had a few people tell me not to run a PC on a generator so not sure how true this is)

If someone can maybe give me some suggestions or solutions for her to be able to power her PC for at least 2-3 hours please let me know.

Her PC specs will be below and she is a animator/editor so lots of rendering so PC will be utilized during this time.

Specs:

i7 9700K (stock)
16GB RAM
NVME + HDD
Corsair R750x PSU(gold)
RTX 2060
2x Monitors 1080p

Please let me know if you guys need more info.

I'm running a Mecer 2400va with 2 x 100ah gel batteries.
Running the TV, signal booster, 2 x routers, 2 lights.
Just tested for an hour mining with 2 pcs.
3080, 3070 and 3060ti. Drops the batteries to 50% in an hour though...
I'd say you'd be fine with this setup.
Just make sure its Gel batteries

Thanks Glen,

Can I ask what this cost you? Do you maybe have links to the gel batteries you use?

Do you ever mine off the batteries or was this just a test?

Hey bud, If you get a decent generator with an avr built in, running a pc is fine. Be careful of all these dud batteries on the market. Too many guys selling batteries that won't last a year. What the gentleman above said about his inverter with his 2x gel batteries and mecer inverter will work for you I'm sure.

Does this system do an immediate switch-over? Like no power drop before it goes on?
Also it says dont connect motors, but I wonder if some fish tank pumps are fine.

Yes there's an entire thread about this device: Mecer 2400VA Inverter (Community Support)

It does immediate switchover (UPS style) and yes don't connect motors since it's modified sine wave which fucks with AC based motors. If the tank pumps are DC they'd be fine

Total cost was R6799.
Got the batteries at R2300ea and the Mecer
R99 was for the cable to link both batteries in series, inverter from PC link for R2000

 

[Glen26]

Was just testing the system out.
It would mine 2 cards comfortably, the 3080 power draw is to much to run all 3 at the same time.

That and conversion efficiency would make the effective cost of electricity quite a lot higher

I got the batteries from Battery man in Hillcrest KZN, the brand is Aokly 100ah gel

Which batteries and where'd ya get the cable made?

I’m also running this set up, we’re getting another one for the lights of the house on the DV board.

We run 2 PCs, 2 switches, a router, fibre converter, POE switch with an AP, a 100in tv, a decoder, Apple TV, laptop charger and a monitor off of it and it easily lasts 4-6 hours. Doesn’t lose a lot of charge so it keeps up with 3/4 sheddings per day. If only it could take solar panels…

Is there a solar option? I also have this inverter but I’d love some solar panels

These are not designed to run to the DB board and it can take solar, just get a controller + panels and you're sorted

Also, your batteries are gonna be toast in a year.

How come they’ll be toast? On the inverter we’re running at roughly 380-500W of the 1440W, basically a 1/3 of whats is available. We’re not over using in fact we’re far more than under using what’s available.

Suggestions for controllers?

How come it can’t run a DB board? What about its own dedicated DB?

Yeah, my work sells them. Pop me a message if you need.

You do get an attachment to add solar to this. It basically is a pwm solar charge controller that connects to to the batteries. Nothing to do with the inverter, really

someone said it is better to go with an MPPT charger?

a reason for the PWM in this situation?

 

[pikolec]

MPPT is much more efficient than PWM, especially if the panel voltage and storage (battery) voltages don't match. PWM will work fine, and is cheaper. Check the 'minister of finance' for guidance This field isn't complex, but there are loads of lessons and tips and tricks. It really does pay to do the research and possibly consult with someone with experience. IAMASE (I am not a solar expert)

 

[Confucius]

For 2 x 100ah batteries in series you would typically want to charge at 0.2C which comes to around 20A. 20A x 24V = 480w. So you don’t need much panels for such a small system.

Yes, mppt is a lot more efficient but also fairly more expensive than pwm and for such a small system not worth it in my opinion unless you have really no space. You would ideally want to get panels with a Vmp in the high 20s or low 30s as anything about that is basically wasted with a pwm charger.
