@Nic The home battery market...

1. I think Tesla's play is more on how to re-purpose used automotive batteries, which is still a good thing. The Powerwall is a great step forward for the Grid, but there are a lot barriers to make this an attractive market outside of California and Hawaii.

2. Prosumer market is a tough one. More consumers are shifting to laptops, and far less dependent on peripherals like printers or dedicated monitors these days. That brings to mind the question, why need a battery for basic home use? For people running dedicated servers at home, we certainly have the technology at the right price to keep you up and running. I think the prosumer market has been moving away from battery backup for a while and will continue to do so as technology advances.

@gjacobse

We have ABM, an advanced method or charging batteries. It does an automatic self check every 30 days. It also turns the charger off when it is not needed so you keep your batteries cool and prolong their lifespan.

@MattSpeller - My take:

Lithium based technologies are great, but who knows how soon they'll come down in price. They're still expensive, many lithium technologies are flammable, and transportation and shipping are becoming more difficult.

There are many 10-year outlooks ahead. The good news is that batteries and energy storage have global research focus from both industry and governments. This should mean the industry will see some major changes in the years to come.

We're really proud of our Intelligent Power Manager (IPM) software. It continues to change the game about how power interacts with IT. We're the first to integrate with virtualization platforms to help manage the virtualization space rather than the physical server alone. We've loved the response from users in the community using these powerful tools and we will continue to provide more benefits in the months to come. Eaton.com/virtualization

The core of our business isn't necessarily power supplies, but power management, a true statement whether it's fuel deliver systems for airplanes, superchargers for top vehicle performance, or UPSs and distribution for datacenters and IT closets. ATX, pro-sumer power supplies are a little out of our focus. We want to position ourselves with products that can improve functionality and interaction for companies that make business happen.

Two easy ways, one hard way.

Easy

1. Add all your IT load wattages together. Done

2. For 120V loads, add all your currents per each "segment" and multiply them all by 120V. If you have three phases, the process is the same: take all the currents, add together, multiply by 120V. Done!

3. For 208V loads, avoid the physics lessons. Take the current on each "segment" and multiply by 208V * SQRT(3). Done!

For those math nerds out there SQRT of three is based off of 120deg phase angle from your unit circle. OK. There are great resources out there on three phase power, but don't make it too complicated. The above equations can get you there.

@art_of_shred @coliver

Yes! These can be somewhat inexpensive. We usually see IT equipment running at 60% or less of nameplate rating. The challenge we have when sizing a UPS or PDU, and you will have too, is that generic rules always bite you at some point. If you are the exception, you risk taking down everything.

Keep in mind that sizing a UPS or PDU at less than 80% or 100% utilization is a good thing. UPSs and PDUs are like the breakers feeding your Christmas tree lights - Once you add too much, the lights go off!

@MattSpeller that picture is going to be their new ad!

Why wouldn't we use it! So gorgeous. I almost cried a little...

@nadnerB - Joseph Eaton started making truck axles and founded our company in 1911!

Maybe just post a new thread!

I meant if there was an instance to include someone from Eaton for question in future threads, who should we ping?

@mdecamp, @windso, or @JColeKen would be your first options

@dafyre , good point, I edit the wording. See above. Really I mean current on each phase. Poorly worded. Sorry!

Are you using SCVMM?

No

Well nuts. I HATE giving this answer, but it depends on what you want to accomplish. Page 3 of our HyperV manual covers the details of what is possible and how. Without SCVMM a lot of the advanced functionality is not possible.

The problem with the 5S1500 for a sever is simply how long the server takes to shutdown versus how long the power will stay running.

under my current load (pretty close to full test yesterday) my two APC 3000XL units (server each have one power cord to each) and one APC 3000 (switches and phone system) all last about 40 mins.

The Eaton 5PX would be the comparable model, specifically the 5PX3000RT. I'd stick to a 5PX1500RT if you need the runtime. The 5PX allows you to use external batteries and extend the runtime form the base unit.

By the way - kudos to the engineer who designed the rack mount EBU's so that you can pull the batteries out, rack it, stuff them back in. My back thanks you.

You bet. Quite a team effort in reality.
