15 customers mention "Power requirement"10 positive5 negative

Customers have mixed opinions about the power requirement of the uninterruptible power supply. Some mention it has plenty of power, a good stable voltage, and provides power during power outages. However, others say it runs down its battery even though everything is not running. The downside is that it won't accommodate the power requirements of all your home theater components and the runtime must be limited.

I originally bought the APC Back-UPS XS BX1000G 1000VA Tower UPS ($125) to protect and provide emergency power for our pellet stove. Once I got it I determined with APC Tech Support help it would not be good for this purpose. So they recommended this one instead because it can handle AC Motor loads and does not change the sinewave that can damage AC Motors. This one though is a great deal more expensive and heavier. However I watched for a "Warehouse Deal" and got this for only $160.00 almost 1/2 of retail plus it included shipping. Hooked it up and it works perfect, "plug and play".

For those that do not know - a pellet stove requires an exhaust fan to run in order to extract smoke to the outside. If your pellet stove is in the burn cycle and the power goes out, chances are smoke will backup in to the house. With this connected it works flawlessly and allows me to shut down the stove and not have any smoke problems. If the power outage is short term it can run the pellet stove for about 40 minutes without AC Power. There are specific systems out there that will run much longer but they are 4-5 times the money and will not power the auto igniter. With this one you don't even know it switched over... I would highly recommend it. Also if you are in a place with long term power outages you can use a generator to provide constant power to the UPS which in turn will smooth out the current and provide exactly what the stove needs. Generators have such a fluctuating current and voltage they can damage the electronics in a pellet stove (as well as any other sensitive electronics). This stops damage from happening.

Also on a side note - for one money we now have our computers protected and will be protecting our TV and related electronics as well.... all around a great piece of equipment for little money!

I have been searching for some time to find a class of UPS's that will "behave" well with my whole home generator. My experience has been that most of the lower end units constantly move on & off line when working on generator power. This quickly depletes the battery & shuts the system down. I worked with technical support of both CyberPower & TrippLite and both were of the opinion that I needed to by an "on-line" unit; despite the feedback on Amazon that these units are not only expensive but also are not designed for "home" use. After taking a look at this class of UPS I thought I would give it a try. The UPS can be configured to accept the "low quality" power from a generator to prevent it from going on & off battery power. I have just completed a generator test with the newly installed unit and the UPS worked flawlessly with my back-up generator. When I tripped the master breaker, the unit went on battery till the generator came on line, after the generator was on line, the unit never went back to battery under various fluctuating load situations. I highly recommend this UPS if one has a back-up generator!
11-17-17 Update-
I just bought my second unit to protect my primary home entertainment equipment (TV, DVR, etc.) because the inexpensive UPS I had hooked up to this equipment would shut down after being on generator after just a short time; it could not handle the minor power fluctuations from my generator. Anyone interested in a UPS to run with a back-up generator should consider this line of UPS...

About two hours before leaving for a long holiday weekend, this UPS started sparking. We rushed it out of the building and it burst into flames! I cannot imagine what would have happened had no one been here.

After the fire burned itself out, we plugged it in again to see if the problem would continue. Sure enough, the sparks started flying and the flames came back. Unbelievable! Goes to show it would have just kept burning worse and worse if we hadn't been there to get it out of the office. APC came a couple hours away from burning down our office building. When we called to report the problem, they couldn't care less. They offered to send a replacement (how could we trust it?!) and weren't even interesting in getting the unit back to see what went wrong. They did tell us if we wanted to send it back, we could, at our cost. Always thought APC was a leader in the UPS industry. Now we're replacing all their products.

I've had what I thought were decent low-cost UPSs like Back-ups 1300/1500, but this is a step above.
My use case is with a small server in my home. I have very infrequent brown-outs and black-outs but had problems with my previous 1300/1500 units (UPS units for some reason occasionally wouldn't respond quickly enough and my server would reboot, etc. Hard drive damage occurred once, prompting me to search for a better UPS option).
The SMT750 seems much more reliable and provides cleaner power (pure sine instead of stepped like my previous low-cost models). The SMT750 has been running reliably for about a year and has handled all power events without any issues.
The built-in interface is more sophisticated than the cheaper models as well-- very nice.
I highly recommend this (SMT750) pure sine unit over the cheaper stepped sine models. If you need more wattage, there are higher power versions available, but I'd say the price is worth it (even with infrequent outages, just one that does damage will make you wish you bought the better unit).
