They're doing the right thing.  They just need to vent that room a lot better.  Keeping batteries buttoned up on a small closet like that is a recipe for disaster.  They out-gas, and you do NOT want that bottled up.

 

Actually in the moving vlogs they say there is high power ventilation system in that room. don't remember which one has him talking about it but you can see it in this shot @5:17

Good deal.  That'll prevent the badness.

How long will that UPS power your smartphone?

 

Will it offer all day battery life for a single smartphone or laptop?

 

You should do a mod where you reduce it to 1 power module and fill the rest of the slots with batteries, then wire in a switching buck regulator for a 5V output, then create the ultimate "portable" (it has wheels) USB power bank for your smart phone.

Why didn't they show it turned on?

They probably need an electrician to wire it in.

Ya this whole time they actually ran out of video ideas so now there making fake videos. Lol.

It's starting to feel like these holy $hit videos are just the old unboxing/first look format but with the price in the title and the what the product is dumbed down to get more clicks.

[Zodiark1593]

Well Linus, apparently half-decent minds think alike, albeit, on vastly different scales. Due to the frequent power outages I've been having lately, I bit the bullet myself yesterday and grabbed a UPS. This is quite funny for some odd reason.

 

Slogan for UPS: They say lightning never strikes twice, but UPS users know even once is too many.

Does anybody else feel that the server room is not adequate enough? Its just a wood and drywall closet... Does not seem to be very fireproof to me. The disconnect breaker also should have a lot more room around the front of it. 100 amps is nothing to play around with. 

You do realize that drywall itself is a fire resistant material right? And you also do realize that if there were to be a fire, the cost of "fire proofing" a room would be pretty high? That's what insurance and backups are for.

 

While 100 amps "is nothing to play around with", you do realize that your home electrical panel most likely has a 200 amp breaker in it too, right? There are clearance requirements for electrical panels though.

Excellent choice, I negotiated Eaton UPS products for our data centres for years replacing APC's a very long time ago.  Fantastic products, not 1 bad thing to say about them.

[Curufinwe_wins]

You know I really like the holy shit line of videos, but you guys really should slow them down a bit. You won't have cool shit to show off after a few more weeks like these last two.

 

It's more like something I'd like to see weekly.

Drywall in itself doesn't give much of a fire rating probably 30 minutes tops. You need to stack them up if you want a decent fire rating. Using mineral/rock wool insulation also bolsters your fire rating. Then seal all penetrations with intumescent sealant and use radiation dampers on all ventilation openings. Then you can get a proper 1 hour+ rating easily.

Except in a power outage the HVAC air handler will shut down and the room could be without ventilation in the middle of summer for an hour with 5000W of equipment running. (It will get boiling hot in there) Just plug a thermostatically controlled blower to the power outlet on the UPS so it comes on if the room temp gets too high.

Nice little box, did you put in a maintenance wrap around in case you need to do work on it?  I used to work for Eaton doing the startup and repairs on the big ones.  That picture is a 4 unit parallel 9390 at 160kVA each.

So do you need a UPS for a small home NAS?

If your using a raid array and have a write cache enabled (for best performance) yes you should have a small UPS that has a USB connection to shut the NAS down properly.

So would it be For 6 HDD's or the riad card?

Well both actually. Especially if your using a hardware raid card and its write cache. The main thing is that you need to gracefully shut down otherwise there is a risk that either the raid card won't flush or the OS will corrupt something in the hard shut down. 

 

Generally speaking unless you disable all write caching even on a regular PC you should have a UPS or you risk data corruption on a power failure. A NAS just has more important data so you really don't want it getting corrupted on a power failure. A raid card is even more vulnerable to a sudden power cut as they can have large DRAM buffers that take some time to flush to the disks.

Why no go with a standby generator? Like this one: 25000w Standby Generator

 

Can run continuously till it runs out of fuel? Also can be non power interrupting? and use the power backups that you already have? 

You would still need a UPS this size to carry the load till the generator can start up after a power failure. And almost always there is an extra delay added after power loss before starting the generator since most outages are short and starting the gens to run for a minute is not a good idea.

 

A UPS is the first step: Keep the load running long enough for a safe shutdown.

 

A generator is the next step: Keep the load running 24/7/365. This is typically not something most need unless power outages are expected frequently.

If the data is important and you already have a backup system in place for it (like an offline external HDDs everything is cloned to periodically then stored somewhere safe), and if you have the budget for it (around $120), then a small UPS would not be a bad idea.

If you have a desktop that is important (like for work), then a single UPS for the both would good.

 

For things like this, you should try a cost-benefit analysis/thought experiment. Example, If my workstation looses power while I'm in the middle of a project and if that causes lose of work that could result in costly delay to recover, or worse, complete lost back to last backup; is this greater than the cost of something that could mitigate this risk?

There is also a stabilization time for the generator itself as well and you generally don't want to suddenly apply all loads to the generator (going from idle to 150% inrush surge could cause a voltage sag, generator trip) Basically you probably want at least 20-30 minutes of backup time to cover any problems like say the automatic starter failing to automatically start.

 

A generator hooked to natural gas can also make fuelling easy (although in a super catastrophic disaster the gas main could be damaged). Having large fuel tanks is a pain due to the chance it might leak.

Generators are usually tested regularly with the load they are to run along with the UPS. I don't think inrush isn't really a factor here as the load is already running normally and the gen will be brought up to level to carry that, the UPS system will manage the transfer of the source from battery to gen once ready.

My experience here is limited, I had a big gen at my first/last job, but I was an entry level part-timer working extra hours for summer at the main office. The only involvement I had in that project was on-site location, unpackaging, and initial base installation of the UPS system for the electricians to complete later after I was back at my at usual campus for fall when the generator would arrive. (I missed all the fun!)

 

You'd size the battery capacity to something like [time to full shutdown] + [generator startup] + [startup delay] + [% safety fudge] < [expected battery capacity after 3 years]. Once runtime gets close [time to full shutdown] without mains returning or backup power online, it should start the automatic shutdown of the load.

 

I live in California, every generator I've seen or dealt with as been natural gas.

Main issue with fuel tanked types is that you have to worry about old fuel. The storage life of diesel is 6-12 months. Liquid propane or similar would be much longer, but with higher setup costs.

I visited this "UPS" last week in Oregon. Capable of powering a city (1.25 mega-watt-hours) of ~160,000 people for 15-20 mins. EATON makes some cool stuff. This is what $25mill can buy you for back up power.

Strange are those yellow wires going to the lithium batteries look like Ethernet cables are they being used for balancing or a pack level monitoring boards.

Yes that is part of the "CAS" system (I think is what they called it because there is no ground). Each battery has a chip in it and they can monitor voltage, temperature and many more. All those go into that rack at the end of the aisle then to the main system.
