Help with short term load shedding solution

TheChamp said:
I get you 100%, buying components and assembling them is most of the time cheaper, I still cannot reconcile myself with the fact that some people believe connecting clearly marked and colour coded cables to clearly marked positive and negative terminals is too much effort for them, but that's just how it is.

Problem is the usage he mentions is going outside the realm of PnP/portability and entering the pro mounted world.

Staying portable would move into 1 unit per PC solutions, which is truly a waste of $$$

I think his usage is fine and I have no beef with the Axpert trolley he found, the only problem is that it will come with cheap batteries if only he could find one that's keenly priced and source his own batteries, I like the fact that lithium batteries can just be added at a later stage.

That Axpert is only good for 1 PC. <--- hence the problem
 
Thanks guys this has been very helpful. Going to start with measuring usage I think I am grossly over estimating it. However seems like if I want it to last its not going to be OK for the 2 pics so I think I'll just get to cover one

Should I get pure sine if its just going to be for the pc and monitors and router

Yes, it looked to me like you had the budget, the Axpert PSW gives you more options for future improvement of the system, that inverter can be mounted and integrated to your DB, solar can be added to assist with the run time and you can connect lithium batteries when your lead acid gives up.

As someone suggested ask Geewiz to put in better batteries not the standard ones, it will push the price slightly up but it's worth it.

Haibo? All 2400 worth of watts for one PC?

100AH X 24V = 2400WH on paper sure
but excludes the 50% rule for lead acid or 60% AGM also power factor(Efficiency)

You looking at 1100WH which doesn't need a masters degree to tell you that 900W of use per hour wont handle for 2 hours never mind 3 ;)

So yes 1 per PC to cover 2 hours and close to 3 hours to make dipping once in a while not dangerous.

Pure sine only matters when you use direct AC like some HiFi Amp's, or things that use motor's

When you have stuff that run on DC power it makes no difference as the device convert whatever AC into DC for use so the modified vs Pure doesn't touch the components.

PC's, monitors or anything that use a transformer does so by converting AC to DC.

TLDR: Does Not matter for the usage you specify.

I've run my PC for just over an hour on the Mecer with 2 105ah batteries. It's a Ryzen 2600, 2060 Super, lots of storage, probably about 300 to 400W. I don't have a killawat used to use a buddies who is now over in Abu Dhabi.

That is why I said get true reading on usage. My gaming rig is a 550W PSU with Nvidia 1060 and i5 bla bla bla.....

I idel at 110W/160W with excel, max performance game I reach about 380W. Destiny 2 for example zaps 240W, so power consumption us usage linked.

OP said average 350W which I doubt, but if true makes 1 trolly is not enough to drive 2 of them.

Also remember power is not a flat line example: My usage yesterday (58" TV + Xbox + 3x10W LEDs and network)

I think Modified Sine is perfectly fine for a PC, specially if you on a tight budget. Personally it is always nice to have a Pure Sine if you can afford it. But I guess there are other factors to consider as well.
 
Currently I am running

2 x PC's,
HP server,
2 routers and ONT,
5 Monitors (1 Dell P 27 and 4 SE 24's),
Ethernet HUB
Speakers

My PC - Doing general tasks and Archicad Teamwork Project. So no Rendering work on GPU.

Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz 4.01 GHz
16 GB RAM
GTX 1070 OC
SSD
HDD

Other PC - Ancient - Power Hog.

Total 350W.


However, when that GPU starts working you can easily add another 150W. I leave GPU intensive work for after Loadshedding.

It’s not the instantaneous power needed, but the fact that the batteries won’t last long enough.

It's not the Axpert that is the problem but the battery, we are in full agreement there.

Yep the 3000W inverter will have no problem supplying 900W, in fact even a 1000W should work fine, the 2400W batteries will be an issue as its not truly 2400.

Again I highly doubt that is his usage...
