UPS recommendation for the following wattage of usage.

[quovadis]

I think you may be living in your own reality.

There’s an entire industry dedicated to providing exactly what he’s looking for. Goal zero, Jackery, eco flow, OmniCharge etc
They all provide the usual outputs in terms of usb etc but also 230v AC outputs.

Sorry I forgot to mention price in the equation and that the products that do the job he won’t want to pay for.

But out of interest can any of them survive a full load shed? And then can they recover quick enough to survive another in the same 24h period?

****

Omnicharge’s cheapest product is $2000 and can charge a laptop once with a peak of 100W AC Output so it’s not going to do this job to start with and not through a load shedding.

The one at almost double the price doesn’t appear to do much more, just has more battery in reserve.

For $2000 (R29,000) you could run your entire (small) house off an inverter and batteries connected to your DB board.

The specifications of the various manufacturers all cater for this scenario - they are essentially prepackaged pure sine wave inverters with integrated batteries and dc input or ac mains charging with a variety of outputs. There are even lifepo4 versions from some although most are lithiumion with guaranteed cycles.

@Thor - You’re an ideal candidate for what is referred to probably incorrectly as a solar generator or portable power station. Something like an appropriately sized Jackery would meet your requirements. Obviously they’re at a slightly premium price because they’re all in one but they’re convenient in terms of size and portability.

Edit: one of these for the tv corner would probably provide 3-4hrs :

They have a smaller one which would be overkill for the network side but would be fine.

Very interesting product.

But can it charge and run at the same time?

The entire sales pitch seems to suggest it would be one or the other and that you wouldn’t have able to “passthrough” with this device inline?

Seems more like a mobile needs-based kind of solution?

Yeah I went to have a look at Omnicharge quickly but it doesn’t seem to be able to do the job required here and is also stupidly priced.

Which would be non-sensical if you could do all the devices in your house for the same money over just a few in one location.

 

[maumau]

I want for simplicity, just plug the multi plug into the UPS device.

Same with the network rack, I don't want to mess with the Synology so also just want to plug the multi plug into the UPS.

(Plug 'n Play Style)

Are you taking orders for when you've built it

As long as your demand is less than the charging capacity it would work fine and no less effectively as a ups than any general solar inverter. The omnis are very much premium products but you’re paying for aesthetic design, size etc.

Just to add: these are very much targeted as convenience items for domestic use where power source is not reliable or you have adhoc power.

I think you may be living in your own reality.

A thing doesn’t exist in that size or capacity or thermal requirements (or price range) because it’s simply not possible.

If it’s the size you want it won’t be able to provide the capacity you want.

If it’s the capacity you want it will be too big.

And if it’s in the place you want in both capacity and size then it will likely overheat.

(And when it does all fit and ticks all the boxes you won’t want to pay for it, although that will still likely be cheaper than trying to do it yourself)

Hence why you do it at the DB board where it’s out of sight and the space and noise issue isn’t such a consequence.

They actually aren’t very bulky at all while also being portable. Best solution for your needs.

Also why do you have a camera pointed at yourself while watching TV? Moonlighting on Onlyfans?

I need 7ah for the network corner


The TV is about 16ah

That's a couple of Vape batteries and a buck converter with a bridge rectifier.

The size is definitely possible.

I thought you wanted plug and play AC?

 

[Mr Scratch]

can i invest? i need a reliable solution to run my washing machine during loadshedding (I cannot afford the 2.five hour downtime!!)

 

[Progenix Oj101]

I have nothing to add, but +1 for the YouTube channel (Technology Connections).

I do, I'm just saying this form factor is most definitely possible and exist.

I still want to build my own that runs via lithium ion, but in the mean time.

I want a UPS to power the Synology and Internet (this is called the Network Corner) and consumes up to 35 watts

I also want a seperate UPS to power the TV and Soundbar, this is called TV corner and uses up to 160 watts.

I do not want a UPS that makes a sound. (primary reason for wanting to build my own, lithium is smaller and I can use LEDs instead of buzzers.

I want the TV corner to be able to run for 2 hours.

I want the network corner to run for up to 4 hours (worst case Eskom scenario).

This calculator says you need about 100 AH @ 12V



So I would say get at least Mercer 720 + 1 x 12V Lead Acid Battery. (Looking around R1600 + R2500)
Or You can go for a simple 650W generator @ R1900 with a 1000VA UPS (R600) as well <- the cheaper option but needs manual connection/Switch over & more maintenance than 1st option.

Nice find!
For the router it seems normal UPS with 2 x 7Ah will work, I just need to remove the buzzer or get a APC which can use software to turn it off.

We need to get those Lithium Ion UPSes going.
A car battery is too much effort on the eye for the TV

Just remember to add your device efficiancy ratio as well.

UPS = 85% so add 15% = 35AH

After reading entire thread I would second the 720 Mercer option and buy LI batteries as you need. UPS consumes 2 much power just for itself and charging a 35+ AH battery will take you forever on a UPS. For example my Mercer takes 9 hours to put 100AH back into the battery and is waaay beefier than a simple UPS.

As for worried about noise next to TV. I have one of the new Mercer 1440 + 2 x 105AH 12V batteries that supply 382W for 4.5 hours right next to mine and we have no complaints:

Do you think that Meccer can work with the LiFePO4 batteries from Blue Nova, because this battery and that inverter I can both put in the drawer, out of sight.

Mercer has to breath, cause heat, esp when running in DC mode. (In fact all inverters needs air)

I know the Mercer can work with Lith-ion and Lead acid, no idea about LifePO4, I'll leave that one to experts.

Lithium-ion ? For real?

Because then it would simplify a lot, If I just buy this inverter and then build my own battery pack like I wanted to do in that other thread using 18650 cells.
