Inverter or UPS in a rack?

Question

Do it yourself

Friends, I thought about installing an inverter and batteries in a server rack instead of a classic UPS. 6kv comes to the rack.
I'm looking at a similar solution and several batteries. The choice fell on this a-electronica.ru/progress-48-6000-hybrid-inverter-...
What could be the pitfalls? In general, if you have experience using such equipment, please tell me. All you need is a consultation. The price of the final solution is very captivating, compared to the same UPS for 6kv. Perhaps there are alternative ways and options?

Answer 1

I have a previous version of this UPS + 8 in my rack (it has 8 and not 6, as in the current one) 42Ah external batteries. The same type of economy option - just batteries on the shelf, and not native external battery packs.
The main difference between UPS and Inverter is the availability of software for interacting with computers.
When the batteries run out, the inverter will simply turn off, the servers will be de-energized. UPS will give a command in advance and the servers will shut down normally. Then the UPS will turn off. Power will appear - the UPS will turn on, the servers will turn on themselves when power is applied.
