Tripp Lite SMART1500LCD 1500VA Rack Mount UPS Battery Backup, 900W, 8 Outlets, PWM Sine Wave, Short Depth 2U Rackmount UPS, AVR, LCD Screen

Huge. I will update in a few months. I received today and wanted to share my experience and provide tips.First, I did not notice ANY odor upon opening the box.Second, It is huge in comparison to APC units I have bought in the past. I was an APC fan until the unit internal systems broke down and would not work with new batteries. I Wanted to try different and narrowed this down to Tripp-Lite and Cyber-Power 1500.Tripp-Lite is 900 watts. I am running:-Intel I-7 core processor-power supply is dynamic 850 WATTS-32 GBs Ram-Windows 10-DELL 24 inch LED monitor-Yamaha Quad speaker with subwooferOutput is at 10%Out Watts 90, which is minimalEstimate backup is roughly 56-60 minutes, which is plenty, given I have a Kohler 20RES 20,000 K (with 200 watt entire house transformer) Generator. I live in Ohio in the country and my local company just randomly tested power and disconnected several homes without warning. I was on the computer when everything when dark. Not good. Then recently, our transform caught on fire. again without warning, and yes, I was computer. I am lucky my computer works at all, hence, reason for generator and buying this unit.Tips:-I recommend before installing, to look at batteries. just unscrew bottom and gingerly pull the front cover off but not too far because wires are connected. You will noticed TWO batteries are required. The support page for Tripp Lite will suggest (as well as in the manual), RBC 51 (two batteries). I suggest you search for RBC 5 battery set. Much cheaper (less than a single RBC 51). Also, I recommend you attempt to pull out batteries to experience the difficulty to replace these batteries. Not bad, but a little tricky.-the surge/battery protect outlets are on the right side (if you are facing the back side of unit), the non-battery outlets with surge protection only are on left side of unit.-Inside the box, the Smart 1500 comes with power (3 prong ground non-brick) cord, a 6 foot USB communication Port cord which needs to be longer (like 8-10 foot). Also, I attempted to use the existing USB port cord from my old APC unit and the computer did not recognize the Trip-Lite unit. This could have been fluke but when I used the 6 foot USB Port cord, it worked and showed in tool bar right side icon, charging. Keep in mind it also would show red x as though battery was not recognized. There is no software and no warranty card in English (it was Española).-when you test the unit, it will drop to 86% battery after testing. Just hold the test button for two seconds. Use mute button to cycle screen like output voltage, output load percent, Etc. when you unit test itself, it automatically will show estimated runtime. It will take about 8 hours to fully restore battery after plugged in so no worries.-Instead of installing software, use Windows, Linux, Mac power manager. Go to Control Panel or equivalent, go to hardware, go to power options go to ;change plan;. Look close and find: Change Advance Power Settings.; Now, scroll all the way to bottom until you see battery;. Click on the plus sign and make sure you set critical battery warning or equivalent if using other operating systems, to &shut down.The battery will charge in about 8-10 hours after you plug in. I will update when the next outage occurs and I will update in terms of when the batteries need replaced (supposedly not for 3 years).I hope this helps for now.Update: 6/19/20. I bought the Tripp lite UPS almost 5 years ago. I replaced the batteries once after about 3 years. The unit recently died. I was downloading Windows V2004 when everything shut off. I freaked out. The unit showed it had full battery charge but the unit would not turn on. So I unplugged everything and plug the PC and Accessories into a surge. Windows, thank God, kept downloading the huge update. I am grateful it did not shut off during install. OMG. I called Tripp*Lite and talked to a human being, which is nice. He was very helpful. He said the unit died and replacement of batteries would not help. So I purchased another 1500 LCDT. This unit works great during power outage. I mean i have had others that did not switch over fast enough. This unit has worked like a charm for 5 years. I have had several power outages and it just works. I know this is expensive but worth it. When I called the company I talked to a human being who was quite helpful. I love Tripp-Lite!

I run a small business doing photo/video/audio restoration/up-scaling/conversion. Time is a premium and having capable, speedy hardware is a must. So I run an Intel Core i7-13700K, 32GB-DDR5-6400, three SSDs, ASUS TUF Gaming RTX4080 16GB GPU, SSL2 audio interface, Blackmagic Design Intensity Pro 4K, etc, etc, etc... all running on an amazing Super Flower PSU; plus two monitors and a large 65" flat panel TV. Every one of these things is plugged into this Tripp Lite UPS, specifically in the outlets connected to the battery. I mention this differentiation, because there are an equal number of outlets that do not use the battery - they are only surge-protected.So this unit has an LCD screen on the front panel with multiple readouts providing various bits of info - so you know what the unit is doing, and how much you're demanding from the unit. (Very handy feature, by the way!) One of those indicators is a 5-bars readout that lets me know how much power I'm drawing from the unit at any given time.At rest, under 0% computer load (meaning everything is powered on, but nothing major is processing at the time), the LCD readout on the UPS shows 1-bar in use. Impressive considering all the hardware I mentioned is all powered on and running (especially since the PSU is 850W alone).Incredible, however, is the fact that when the system is rendering video it draws significant amounts of power - pretty much every component in the computer is demanding 95-100% power draw - and this UPS LCD readout only shows three bars lit, with the 4th bar occasionally blipping every now and then.Amazing. This computer pulls considerable power under heavy loads like that (demanding pretty much all 850W from the PSU), and this battery backup has handled every instance with incredible ease, and plenty of room to spare. Color me impressed. WELL worth the money, as it has saved me from more than one power outage during this year's stormy season.If you've got devices that require significant power draws but also need the safety net of a capable battery backup, I'd recommend this UPS all day long.Kudos to Tripp Lite for another excellent, capable, quality product. Cheers!
