Tripp Lite OMNI1500LCDT 1500VA UPS Battery Back Up AVR LCD Display 10 Outlets 120V 810W Tel & Coax Protection USB, 3 Year Warranty & $250,000 Insurance, Black

Very Good
Perfect. After suffering through 4-5 CyberPower units, which are pure, unreliable garbage, this unit is terrific! It power conditions and maintains power even if the voltage dips.

Working fine for five years now (replaced batteries at 3 year mark)
Batteries died pretty much exactly at the three year mark (expected lifetime is 3-5 years, I believe). I was worried that maybe the unit itself died, but once I replaced the batteries it worked perfectly fine, and has been going for two more years now.

Off to a rocky start – Listed dimensions are WRONG
Listed dimensions are WRONGTurned unit “off” thinking I was turning it “on”.Details of what happened below.Instructions from the quick installation guide on page 3 :STEP 1: Plug the UPS into a properly grounded outlet.After plugging the UPS into a wall outlet, press and hold the POWER BUTTON for onesecond to turn on the UPS (See Basic Operation Section).Notes :• The UPS will not turn on automatically in the presence of live utility power.—————————————Really? Notes say “UPS will not turn on automatically”? This is What actually happened below.I plugged it in and the unit turned itself on, as in, all the way on. The online icon was lit, but I was not sure because it says push on button and a beep will sound indicating it is on, this is on page 4 it says when turning the unit on it will beep once.So I pushed the button and it turned off with a beep. So I thought I “turned it on” because in the instructions it does not say the “online icon” will show indication the “unit is on”.Second page of instructions same thing.Then down in a section called “optional installation” on the quick installation page 3 it does say something about the online icon indicated the unit is on.Really? Did I just turn this unit off? Thinking I turned it on? Seems so.In all the instructions on any page it says NOTHING about push “on” button and the “online icon” will show the unit is on “in the same sentence”, it just says push on button and the unit will beep once.So when you plug it in, as I did, and it comes on all the way, like me you might not realize when you push the on button and it beeps you are actually “turning it off”, because it beeps when turning off and turning on via the on button.Well upon further investigation etc, I realized the “online icon” indicated the unit is “ON” as that is kind of obvious it should says that when the unit is all the way on.I think most people will figure this out or with most units when you first plug it in maybe the unit does not turn itself on, actually on with the online icon lit like mine did???If you buy one of these watch to see if, when initially plugged in, it comes on, or, goes all the way on with the online icon lit like mine did.I do wish the instruction where more clear and said:To turn unit on, Push/hold center on/off button, hear short beep and see the online icon come on confirming the unit is now “ON”. all in once sentence just like that.Next: To turn unit off push/hold center on/off button here short beep and the online icon will go off confirming the unit is now “OFF”—————————————-Second gripe: Dimensions stated in the amazon description are WRONG as of august 2022 when I purchased my unit.Hopefully some one at TRIPP LITE will read this or an amazon person will see this and fix it.Amazon description says: Item Dimensions LxWxH 19.29 x 9 x 11 inches. Upon further research I found this is the unit “box” dimensions.Actual dimensions as stated in the PDF info page: UPS Power Module Dimensions (hwd, in.) 8 x 5.75 x 15.6 – this was confirmed by me with a tape measure.When I measured the actual unit I thought I was cheated and sent a smaller unit so I began checking. The box it came in, and, it did indeed say unit size: 8 x 5.75 x 15.6. also, box did show correct part number for what I ordered.Online research did confirm, yes, 8 x 5.75 x 15.6 are the actual unit dimensions.—I clicked on the report incorrect product information link, nothing happens, no way to report this dimensional “disinformation”.So off to a some what confusing and rocky start with this unit. Really hope things do not go “down hill” from here.I will report back later with updates if needed.Note: I have extensive IT and UPS experience. I have been using these things since the mid 1990’s and have bought a lot of them, mostly APC brand. I have had them go bad quickly and others last literally for ever with many battery replacements.I am hoping to have a good experience with the Tripp lite brand. Aside from the confusing instructions I can not fault the unit at all so far. Though just unpacked it and plugged it in….

Honor their Word
Tripplite is awesome. I have been twice hit by lightning (Florida) and both times they have not only replaced all their devices and/or upgraded them promptly and without argument, but also sent me checks to cover all devices plugged in as per their promised insurance meaning, to date, I have been given far more than they cost. For this reason, I have everything in the house connected to their devices. Our power fluctuates, these devices handle that issue and serve as great backups when needed. The woman I worked with there Yvonne was there for the first strike, gave me her personal contact number and helped me with the second strike as well. If you are having issues, give their support a try – somewhere there hopefully are still the same great values that helped me.

Disclosure and confession: I spent two decades reviewing UPS systems for several of the largest computer magazines, almost on a yearly basis, and got to know the players in the field quite well, along with their advantages and disadvantages. In almost all the reviews, Tripp-Lite would end up at or near the top of the list of products for their superb engineering, rugged design, and support. Over the years, I’ve bought quite a few UPSs for personal use, and the vast majority have been Tripp Lites.So, after buying another high-end computer with all-SSD storage, and suffering through five power glitches in a week of bad weather, it was time to buy another UPS. It was, quite frankly, a no-brainer. This was the unit I chose, based on several facts: I like to have extra capacity in the output, so I wanted at least a 1200VA model, the construction was extremely solid, and the price was competitive. I have not been disappointed. The UPS arrived next day (despite not paying for next-day shipment!), got plugged in, and went to work immediately.These are not the world’s most attractive UPSs, but they are not ugly either, and they are designed to minimize heat and noise. The documentation is still (twenty years later!) mediocre at best, but all you need to know is on one or two pages, and the software (if you want to connect the UPS to your computer) needs to be downloaded and is, at best, acceptable. Other vendors have nicer designs, better-written manuals, and better software, but after comparing this Tripp Lite with older Tripp Lites and some other manufacturers’ units already in my house, I still strongly believe the Tripp Lite is the best built and best designed unit. A very good friend is a protection engineer, and she took the unit apart and pronounced the engineering “excellent”.If you want a space-age design and fancy software, then look elsewhere. If you want a UPS that is solid, rugged, reliable, and will be trouble-free for years, then this is one of your best choices. I have some Tripp Lites that have lasted close to a decade on the same battery, and have never seen one of their units fail (unlike some of the other UPS vendors). Extremely solid unit, and strongly recommended.

it’s perfect , now my home theater is secure

The unit seems to be working but it emits a very noticeable buzzing sound. Don’t notice it until evening or morning when there is no other noise. I don’t think I’d get another one based on that.
