        Beware of the power required

        I've withdrawn my previous comment as I'm not really happy with it any more.
        The inverter works very well if you have equipment that consumes little connected to it.
        Generally speaking, it runs well without any problems and in the event of a power cut, it takes over and beeps to warn you (I still haven't worked out how to stop the beeping that goes on for 30 minutes and it's really annoying).
        But the problem I encountered was linked to the power of the device.
        The specifications of the device indicate the power in watts, which I thought was for the "battery" mode. But no, it's for general use. As a result, I have a powerful PC and sometimes need a lot of power to carry out my tasks (video compilation, 3D, etc.), but apparently the device restricts this and keeps beeping to indicate a fault. It's very annoying and I don't really need it...
        If you plug in something that doesn't consume much, it's fine, but if you plug in devices whose consumption fluctuates and may exceed the maximum power of the inverter, then it's not fine. Especially as the limiting power is indicated "offline" on the description.
        I regret this purchase and not having had this information beforehand, hence this detailed review, in the hope that others won't be fooled.

        a sure thing

        The whole company is equipped, and they've already saved our bacon more than once between micro outages and longer interruptions. Highly recommended!

        Purchase of 2 inverters

        Because I was satisfied. The delivery took a little while, the parcel stayed 6 days at Chronoposte.

        Good value for money.

        As usual, there's no surprise here - the quality is spot on. This inverter does the job silently, perfect for a PC and a monitor.
        As for the transport, I had to collect the parcel from another location further away.
        There are always problems with the post, which is why I'm not giving it 5 stars.

        Perfect

        Contrary to what the documentation and Eaton's technical service say, this UPS is fully compatible with Ubuntu (22.04) and can be managed with IPP.

        Shared. Violent storm, my computer shut down, So I wonder...

        Shared. Severe storm, my computer shut down, so I'm wondering... Was it really too strong, or did the inverter fail?

        Effective product

        The first device I received was defective. It was exchanged by Eaton's after-sales service without any problems and without long discussions. The new inverter works without any problem

        Perfect

        Second model I've bought, still very satisfied. I've had the first one for 5 years (GEN 1 black) with my box and NAS plugged into it, and it has withstood one hour outages without a problem. I've had a lot of micro outages on my network, so my devices are protected. On the new one I have a gas boiler connected to it so I still have heating and hot water in case of power failure!

        Lasted 4 months...

        It lasted 4 months before the battery finally died...so I can't plug my PC into it anymore, it doesn't work unless I go through the ct without a battery.for the price really sucks.

        effective

        The EATON 3S 550 FR has already recovered several times from power cuts in these cold weather conditions, just what I needed to avoid damaging the computer

        Satisfied

        I have been using it for a few weeks now and it has protected my box from frequent power outages lately. I've had it for a few weeks now and it has protected my box well against the frequent and untimely power cuts of late. The inverter is a bit oversized for this function. Who can do more can do less.

        Eaton 3S 550 EN (Gen 2)

        I ordered this inverter to replace an Eaton Protection Station 500 which stopped working after 7 years of service, I took back an inverter of the same brand having had no problems with the previous one.

        I would like to thank you for your excellent service and for your excellent product. I have been very pleased with the service and the quality of the product and the service provided.

        Perfect!

        Easy to install, configure and use. I plugged it into my Synology DS216 NAS, without a problem, it was instantly recognized. After a few tests, it works perfectly! I recommend it.

        does the job

        Good service/price ratio.
        Power outage tested with 2 NAS on the UPS, the announced time on battery is kept. The UPS is recognised by the USB-connected SYNOLOGY and the second NAS is informed of the power status by the first.
        I am satisfied.
