UPS recomendation

[Igor Gorjanc]

What UPS do you recommend?

 

Requirements:

- rack mounted

- support for Windows Server graceful shutdown before battery is empty

- line-interactive or online (NOT standby)

- 15-30 min at 500-1000W

APC (Schneider) is basically the standard here. With the understanding that you'd need to replace the batteries, you can find used ones on ebay et all for not too much money.

What's your budget? 30min at 1kW from a "standard" UPS will probably set you off 2.5-3 grand or so...

 

There are power stations that could do it for way less but then you lose the rack mountability and online/line interactive requirements...

We use mostly Eaton at work.  Personally, for my stuff at home I stopped using UPSs and moved to power stations.  The cheap lead acid batteries are so fragile.  I'd have to pay several thousand for a good LifePO4 model and that would annoy the crap out of me at home with the fans.

 

EDIT: I actually have 10kw in the garage on an inverter feeding 2x20amp circuits (one just has a fridge and garage door on it), one going to the office.  It is fed/charged by a  120v30a outlet.  I had them put it in when they did my 240v50a line for the car.

And most of the ones I've seen require 240V

I haven't seen a UPS without NUT support in nearly a decade so unless you're planning to roll your own this shouldn't be an issue

We have 240V 50Hz, so this is not a problem.
