UPS functionality good enough for IT equipment? - does ESS mode influence UPS quality?

Two (possibly simple) questions:

Is the UPS functionality good / quick enough for using a Victron system (3x Quattro 8k) as an uninterruptible power supply for IT equipment?


Does using ESS have effect on this UPS function? (good or bad)

I've never had IT equipment suffer any ill effect of grid failure. MultiPlus has performed this function just fine ESS or no ESS, no difference for me.

We have an issue with a MK2 3kVA on a server rack. We have never - not on one site - seen changeover slow enough that it affects electronic equipment like servers etc but on this critical installation the equipment has gone down twice now. The client IT Manager is understandably angry and wants us to pull it all out.

Thinking about it, the main difference between a normal UPS and a Victron MultiPlus is that a UPS is “in line” and doesn’t just pass through. Ie. It will rectify the AC input until it goes away and then within a few ms (2?) it will invert from battery of grid goes away.

Could we safely replace this functionally by removing the MultiPlus and putting in a Phoenix and a Battery Charger or are we on a fools errand trying to use Victron for a UPS.

I agreed to this job on the basis that the box says “Telecommunication” and my own personal experience is that I’ve never seen an issue during changeover.

I have a lot of servers on multi's working just fine in ups mode.

I don't think ESS has effect on the switching @ power failure.

I live in kenya and work in IT and we have regular grid outages.

I have used multiplus 1200 and multiples 1600 in standalone mode and also a pair of 1600 in parallel.

for most cases with inverters in standalone mode IT gear (dell and hp servers, pcs, network switches and routers) doesn’t notice the switch over.

with the inverters in parallel it’s a different story. The change over seems slower and some gear doesn’t like this. dlink switches in particular.

I ended up putting small ups units (Mecer 2kw rack mounted) in front of the paralleled inverters and everything was fine.

Ymmv.
