    A great replacement for APC-abandoned UPS

    I am a long-time APC UPS user. Both of my quite old 1500 KVA UPSs needed replacement batteries, which I bought from a 3rd party vendor as APC no longer supported them. Once replaced, I found that the control panel on each had also failed and could not be replaced. I was out $150 for the batteries and the devices were surpluses. I bought a pair of CyberPower LX1500GU3 UPSs. They work beautifully. The PowerPanel-Personal (PPP) software does a good job of logging and reporting the condition of a UPS. One important point, however, is that this software only supports a single UPS attached to a computer. Thus, to monitor two UPSs, I must quit PPP, switch the input (I bought a simple USB 2-in, 1-out switch) and restart the app. This works, but there are two issues. (1) you only can a log of the device currently only and not the other, and (2) when you install PPP, you enter the SN which is then permanent. Thus, the log for both devices indicates the same SN. The LX1500GU3 does not have the necessary board to allow it to connect to a network, so the PowerPanel-Management version of the software cannot be used to track two UPS with a single computer as was suggested by one tech support person, but shown not to be possible by another. I have suggested to Tech Support that a simple mod of PPP in which the software displays a list of UPSs attached to the computer is presented, from which the user chooses one UPS. The software then picks up the model and serial number of that device and provides logging exactly as at present. One could then execute a second instance of the program which could pick up the info for the second UPS. In fact, if done more generally, the idea would allow launching "n" instances to track a number of UPS. This would be a real benefit to small home users. In terms of device performance, these are supper UPSs and the tech support via chat is excellent.

    We have been having brownouts where I live. I didn’t want my Roomba to fail because of the grids fluctuating electricity. So I bought this ups to protect my investment. I bought a second one from the same company through Best Buy that is sine wave for my network to avoid damage to my mesh system and have plenty of room to add a TV and security systems hard drive.

    Look, I have three of these that I've been using for 3-4 yrs and all have served their purpose without fail. Reading through negative reviews makes me wonder if they aren't just competitor "paid bashers". That's actually a thing.

    Easy to set up and customize depending upon how your house current fluctuates if at all. Software downloads fast for automated shutdown of your cpu and accessories. I love knowing a true sinewave (60hz) is produced, allowing sensitive electronics to have a longer life cycle. With self checks, voltage customization, USB/C and easy setup, it works for this house.

    Excellent at what it does. I live in a building with power fluctuations, so the AVR is essential and the battery backup has given me plenty of time to save my work and shut down normally when the power goes out. I used the previous model for over a decade so when the time came to replace it there was no question.

    I would be giving this 5 stars but I've yet to see it in operation (our power has been stable since I got it). Love the fact that I can power and protect my computer, 3 monitors, internet modem and wifi transmitter. Plus charge my phone, et al.

    This is a less fancy version of UPS. It does the job well. Setup was easy. It has USB A and C type of charging port on the front side, which can be handy to use. Enough power to drive a water cooled PC system with powerful graphic card.
