Need A New UPS�Which One WON�T Burn Down The House

You might look at CyberPower if you haven't already.

I suspect the batteries are probably from one or two manufactures and rebranded though. I could be wrong in that assumption but that seems to be way things are these days.

Good luck and keep a smoke alarm and a fire extinguisher handy. (Actually I do that).

I typically just deal with the big APC stuff like the 6k series and such...

However, I recently put together a prototype job box mobile workstation for construction sites and put in a 1U rackmount Cyberpower unit. Its out at Tesla right now. No issues with it or anything. Its been there for 6 months or so now.

Come to think of it I am pretty sure the brick that runs my home server stuff is a Cyberpower. I know for a fact I've replaced the batteries at least once because I swiped them from work since they are the same raw batteries once you strip them out of the assembled modules. I bought that back in 2012 if I remember correctly.

I have three Cyberpower UPS, one 1500 VA and two 1000 VA units. All three are over 10 years old. I had to do was replace the SLA batteries two years ago because the old ones were worn out. That is to be expected after having them for so long. The new cells are 9 AH which is a nice upgrade over the old 7 AH batteries. I tested it and they did last about 25% longer than the old batteries were calculated to run. A set of four cells was just $75.

Reliability wise, I find Cyberpower and APC to be about on par. However, the interface software for Cyberpower is always giving me grief, at least the current version. Now granted my experience are with older units from both company and I haven't bought any of the newer APC UPS so I can't say how prevalent these fire hazard failures are currently.

Cyberpower supposedly can’t do hot-swaps, so it’s off the list.

Thats not true

Thats the one I put into the job box.

Is this for your house or a workplace?

Thats the one I put into the job box.

Doesn’t say anywhere on that page that it can hot-swap. Multiple reviews state there is a cutoff switch inside the battery box that shuts the units down when the cover is removed.

Also this:

Our patented Bypass Design allows current to bypass the transformer and automatic voltage regulation (AVR) when utility power is normal, thus reducing energy consumption and associated costs. Because utility power functions normally most of the time, the bypass design allows for substantial energy savings. This technology also reduces heat generation, an important factor in decreasing operating costs.

Sorry, but a cutover-UPS is not line interactive, no matter how much they try to spin it.

Compared to the 22-y/o APC this is near worthless.

Is this for your house or a workplace?

My house is my workplace. I have a small server room.

Here are the specs for the old unit:

They have a direct replacement, but at 2U, and not able to be stood on its side, along with the reduction in APC quality, I’m looking elsewhere.

I’m trying to get more info on this unit, to see if it can hot-swap cells:

Click on the specifications tab. It specifically says hot swappable: yes

Heres a screencap



This is a small model. They have bigger ones.

I'm not tied to the brand or anything. I just got it because the specs were what we needed for a specific project and I could get it next day or whatever. But you should still have accurate information to base your decision on.

Also researching Battery Backup Power, Inc. devices.

It’s a CA company, but can’t determine if their UPSs are made here or in Asia. Likely the latter.

Pros:

• Online double conversion with isolation transformers. This is the highest level of protection you can achieve for line conditioning, and usually requires separate components.

• Models with optional LiFePO4 batteries, with 3, 5 or 10 year lifespans (batteries), depending on use case.

• Up to 5 battery chassis can be added, daisy chained, so up to 10 KVA for their 2u bricks, depending on model (1hr runtime at max load, with 5 packs).

• They mainly seem to support the scientific laboratory community, that often has very sensitive power needs, so quality seems decent.

• Certain models have breakout PDU boxes for multiple plug types and voltage / amperage. 3-phase is available.

Cons:

• Expensive. 1-2K per KVA for the models with the features listed. They do have smaller, less-functional units, for cheaper.
