LDLC: Delivered very quickly. Additional one-year warranty at no extra cost. Repair possible in case. Precise information on the phone and reactivity on email.
Product: Efficient. Quiet. I liked the setting options for managing secondary sockets and the control screen had everything I needed.
Nothing to complain about apart from the postage costs, which I would have appreciated being lower.
Purchased to protect and power a fixed PC in the event of a power cut. There are 4 power sockets, so it's perfect for connecting the CPU, two monitors and speakers.
Too noisy for a quiet personal office, this device generates a continuous noise of about 40db with peaks every 5 seconds at about 45db; even with about -10Db at a distance of one meter this remains excessive in a quiet personal office; not sure for this reason to want to keep this equipment.
The battery supplied was not recognized, it was necessary to pass by the service guarantee of the manufacturer, which did not make difficulty to deliver a complete equipment in replacement, with nevertheless with the final ten days of unavailability.
I was a little disappointed by the fact that the management of the device requires a USB connection, which when the main protected equipment is a NAS does not allow the use of the control software supplied with the UPS; I was probably naively expecting an SNMP type function allowing it to be done via the network.
Note that out of the 6 sockets only 3 are protected by the battery, the other 3 are only protected against power surges; and that the power saving function when the master is switched off only makes sense in the case of use with a computer as master, and not with a NAS.
Advertised capacity 900 VA
Verified capacity 56 VA (power supply for a server consuming 24VA, battery empty after 2h and 20 min)
I would like an exchange of the product or a replacement of the battery, apparently defective
I ordered this inverter, which seems to be of good quality, the display is nice, but contrary to what I read, it buzzes at 50hz with a little click every 5 seconds. It's not very loud, but you can't help but hear it in a quiet room like an office, and after a day I couldn't get used to it.
It is made in the Philippines
I gave it 5 stars despite a malfunction with the first UPS I received (it happens). My DS1621+ NAS takes control of the UPS without a problem.
I am reassured now that the UPS is working especially with so much data on the NAS!
Also 5 stars to LDLC and thank you for the excellent service that made me a standard exchange :)
The APC Back-UPS Pro 900G does its job perfectly. Simple installation and flawless operation.
I received it on time (fast), good packaging. The product was just what I expected and extremely quiet compared to my Eaton. I'm very pleased with the quality of the product and the service.
Received correctly, box in very good condition.
Installed 15 minutes ago.
No worries then it starts to emit small clicks, several sparks appear on the top of the casing then a very strong smell of burning.
The inverter is outside, "cooling down" before burning down my house...
The whole city centre was cut off !!! in total almost one hour ...
I had plenty of time to shut down my server with two disk clusters ...
It lasted 30 minutes ...
Big blade server ....
Used to protect my audio equipment (pro studio), it will have lasted until 6 months after the end of the warranty, that is to say two and a half years... that's not much!
To replace the too old UPS of my backup NAS at my mother's house,
I'm looking at the current inverters, and I'm surprised to see that this 900G PRO still exists: it's the one that has been protecting my main NAS for 6 years... ^_^
6 years without worries, does the job perfectly (with 1 computer + 2 monitors + 1 NAS 4 HDD + Switch + Box)...
On the other hand, I withdraw half a star, because in March 2014, I bought it 160€ at LDLC, and 240€ in May 2020! 150% increase in 6 years!
I take off another half star, for the packaging: no over-packaging, just the original, super thin cardboard box; with inevitably the handles ripped off by the carrier when he uses them to pull such a thin and heavy box...
I received my package this morning, as expected, installed and well supported by my iMac under Catalina, without the software that came with it.
Already my second UPS-PRO 900G.
Very easy to use, quiet and temperature correct.
One for multimedia and the other for an aquarium.
I already had the same inverter and was very happy with the services it provided. I bought a second one to protect a PC, a video projector, a home cinema amplifier and a games console. It does its job perfectly...
The UPS was received in perfect condition
I'm going to live in Spain where in the region the variations and cuts are quite frequent despite the optical fibre.
For my Synology 2 bays it is almost indispensable.
The APC quality is not to be faulted.
I recommend
Conforms to the detailed features. Tested with a rather unstable mains supply (one surge per day on average with significant voltage fluctuation). In addition, its status variables can be read via the NUT protocol under Linux (USB usbhid-ups driver and nut program stack. see https://www.piapplications.eu/fr/articles/doc-0071.html). The NUT protocol also makes it possible to monitor its status from another machine with a suitable "client". It is therefore not reserved only for 'Windows' if one is satisfied with the knowledge of its state in operation.
Reliable, powerful enough for a computer, a server or a 3D printer (my case) and above all very intuitive in the settings.
Very good value for money. Does its job very well.
In short, nothing surprising for APC :) I highly recommend this UPS.
The only drawback is the delivery. I received it with the original box (no film to protect it or cardboard) with two holes as big as the dot. The inverter works perfectly despite this, which proves its resistance.
LDLC packaging is non-existent, so the box arrived with rough corners (the first package disappeared).
Good inverter and good quality construction.
Indications on the front panel very practical.
The software settings are quite complete.
The downsides:
- Noise of tranfo and quite annoying when it is in full OFF position but connected to 220v, I just had to unplug it from the socket to solve this problem.
- The 3 buttons remain lit but in the standby position, which is annoying if the inverter is in a room.
I have to say that I am very pleased with the quality of the product and the quality of the service. I am very pleased with the quality of the product and the quality of the service and the quality of the service.

I'm not sure if it's a good one or not.
I'm not sure if it's a good one or not.
Purchased to replace a very old APC smart-UPS 750, which had broken down after 10 years with no problems.
Easy and quick installation. It works perfectly as soon as it is plugged into the mains, and its screen allows you to quickly see the different parameters. Very practical.
The device was received in the manufacturer's packaging and suffered during transport. The device was received in the manufacturer's packaging and was damaged during transport, so a more robust protection would be welcome.
I'm very pleased with the quality of the product and the service.
No difficulty to install, an explanatory note is provided. The small software, not necessarily essential, informs about the consumption of the machines connected to the inverter and allows some basic settings.
Interesting product that does its job and is very well suited to a high consumption Gamers computer (370W in game).
The software does not seem to display power outages.
I have been using this product for some time now and it has been a great help to me. I am very pleased with the quality of the product and the quality of the service.
The mac was plugged into the right socket on the back up and the usb cable to the imac and that was it.
The Imac said ok I saw a new icon at the top, it's taken into account, it works.
900w for an imac 24 4 external hard drives a box a gigaset wireless phone: back up load at 30%.
280w, the evening with the indicator of consumption in watts I realized that the fact of turning off the screen it was 50w less.
Satisfied
perfect inverter for my use; easy to install
I've been using it for a while now, but it's a great tool for me to use.
I've been using it for a while now and I'm very pleased with the quality of the product. I'm very pleased with the quality of the product.
It replaces an old BR-800, and I must admit that its display is very practical.
No noise, even in battery mode.
2 NAS plugged into it, and a freebox, can be maintained for 35 minutes in standby.
I've just received this product and it's still excellent (yes, it's Chrono, but next day delivery is a must have! :) )
I've been using it for a while now, but it's a great product, I've been able to connect my 3 Syno NAS + my gaming PC and it's still going strong, it gives me 10-13 minutes of autonomy, plenty of time to turn off all my stuff.
I'm disappointed that the APC software still doesn't have the possibility of launching an external script in the event of a switch on the UPS so that the machines can be shut down automatically, I had to search the net to find something to do my shutdown by myself.
This inverter meets my needs perfectly.
Having several servers at home, it has become vital to avoid problems related to power outages.
This UPS has 6 outlets in total, each one is protected against surges so I have connected all my sensitive installation on it.
Of these 6 outlets only 3 are backed up by the battery.
Concerning the switchover time, it is largely bearable for all the IT. After several simulations, none of my equipment felt the switchover to the battery, each remained active without any difference.
This UPS has a beep that warns us during routine operations (switching to battery, battery status. This beep can be disabled.
It has a screen that indicates the mains voltage and the voltage produced by the battery in the event of a mains failure.
There is also a charge indicator to know if your equipment is drawing too much or not.
As far as the noise level is concerned, there is a slight transformer noise when starting up, but this disappears after 20 seconds.
Really great. No negative remarks
Silent, reactive, discreet: in fact, if not to have an eye on the beautiful display on a blue background, one would end up forgetting it, a guarantee of efficiency. The information is useful, we no longer fear the storm ... always provide a ratio of 0.6 (or less: 0.55, 0.50, depending on the inverter): 900 va = 540 w max. It will be 3 years in november, always the same battery (the pc is never stopped)...A must in this matter
Very good inverter, it can also protect the telephone line and the RJ45 network.
There is a usb output to connect to the PC, recognised by Windows as a battery, a bit like a laptop.
The software provided is not really essential, it replaces the Windows power manager without really bringing anything new except the possibility to cut the power of the equipment automatically when the PC is stopped for example.
In my case, it protects a server with several backup disks as well as the box + switch without any problems.
I received the device very quickly but without any over-wrapping (packaging has always been LDLC's BIG flaw), very disappointed as soon as I plugged it in because of the noise it made (noise of an electric transformer that I could hear at more than 10m at night from another room).
After a few exchanges with APC support, they sent me a new device.
The after sales service is very efficient.
However, this new inverter is still not silent!
It is much quieter than the first model I had, but it is not totally silent (as for example the ES 550 model I also own). In terms of volume, to give an idea, it makes as much noise as a 2.5" hard drive when it is running slowly.
In the end, placed under a desk, I ended up forgetting about it.
The manual does not even explain the different displays that the screen can provide.
And it's a pity about the outage counter that the inverter integrates. It just displays the number of outages, but nothing else.
If you think that the software part can get around this problem, well no.
At best, if your PC is on, it will be turned off by the UPS, but in the evening when you get home, you will see "1" on the UPS, but how long did the outage last? 5min? 8hrs? impossible to tell by the UPS. (It's my NAS that gives me this info with the time it turns back on)
Last problem: the life of the batteries, it is indicated for 3 to 6 years only (my Cyberfort 500 UPS which is 15 years old still works perfectly well!)
Moreover, the 1st model I received was manufactured in August 2015 and the 2nd in April 2015, so the battery is already 1 year old before I even used it...
The finish is not "professional" at all, it's cheap plastic and there are even small pieces of plastic cut between the LCD screen and the glass.
We'll have to see how it ages over time.
Quiet inverter (I only hear my PC at the foot of my bed), the LCD (display of various information) is extremely appreciated, possible to see: the consumption in instantaneous, the percentage of use, the autonomy available, ...
the inverter is amply sufficient for my use. The MASTER plug is very efficient. I recommend it even if a more complete user manual would have been appreciated.
I bought this UPS to connect to my Synology NAS with 4 hard drives.
Well, it's way overkill! In standby the NAS draws 3% of the UPS capacity.
Very good integration with DSM, we are informed of any power cuts directly in the interface. In addition, the buttons and the screen are very practical to see the history and the live performance.
Very good product.
Used with a workstation (tower screen printer scanner etc) plus a synology server, two routers and the landline phone which gives me 30 minutes of autonomy at full load (I took it oversized on purpose)
The good points :
The price, which remains affordable for work at home;
Quiet;
Very simple battery replacement procedure;
Connected to the PC to trigger automatic procedures just in case;
And the auto shutdown of the slave sockets when the main equipment is switched off on the master socket: so simple, so useful .... A really good idea!
Indispensable on fluctuating electrical networks like those in the countryside
Product arrived damaged (internal part disconnected and housing damaged). I'm not sure if I'm going to be able to get the product to the shop, but I'm sure I'll be able to get the product to the store. I'm not sure I'll be able to get the product to the store, but I'm not sure I'll be able to get the product to the store.
Waiting for a reply from the after sales service...
