Tripp Lite 1500W Compact Pure Sine Wave Power Inverter, 3 Outlets, 1 USB + 1 USB-C Charging Ports, Remote Control via RJ12 Telephone Cable, Included Mounting Brackets, 2-Year Warranty (PINV1500SW-120)

EDIT! Update as of November 28, 2014I have been using this for 4 years so far and it has helped me tons during power failures (even giant storms that knock out the power for days). I normally use this for computers mostly, but in case a huge storm knocks out power (hurricanes, durachios, etc.) I can at least keep all my food frozen solid (although defrosting it and eating it becomes a problem). With a large enough battery I was able to run it for about 2-3 days along with other rotary cooling devices. During longer power failures I would suggest attaching solar panels and a charge controller to the battery to help out, but NEVER when the AC comes back on.Also, when I had this temporarily attached to a gasoline generator (bad idea) the UPS works quite well for its intended function in AC mode. What I mean by this is that in AC mode it will correct the output waveform so it is consistent (120V) as the UPS conditions the line. So if you are powering the UPS off very bad AC power (generators, bad power companies, etc.) you may notice that the battery does not even charge at all because the UPS keeps conditioning the power. In that event, the only way to charge it is when nothing is attached to it (nothing plugged in to get power).Also, when I attached this to a Kill-a-Watt the PF is almost nearly 1.0 at around 0.90-0.95 or so, but the Kill-a-Watt is a cheap measuring device so it might not be that accurate.And another note that if this is attached to any GFCI plug, the GFCI will trip. However, all my other UPSes trip GFCIs anyway.EDIT! Old Review: March 17, 2011; Edit 1: May 10, 2011As of May 10, 2011, the unit still works properly.I have had this unit for 6 months and despite probably being hooked up improperly still works as it should. After a massive day long powerfailure with a bunch of powerfailures before I got tired of the electrical setup where I was and just decided to get a UPS. Since I had it setup, there have been a bunch of micro power failures, voltage dips, and such. I bought a gigantic battery, but my load is currently 130W so this is probably overkill for what I use on average, but if I ever need to pull a larger load I will not have to worry about that. However with such a large battery and a small load you can keep whatever's plugged into it on for a long time hopefully, I hope the better part of 2 days. << DO NOT DO THIS >> The holes where you plug the cables into are small, so I just screwed the screw like things up into the battery loops, which might not be the safest thing to do. Not sure about that however. It does work and has worked with 300W loads just fine. If anyone has a link to a much better cable, that would be very appreciated so I could get a proper setup. A small adapter thing would work also so I can just latch my existing cable onto them. << DO NOT DO THIS >> << DO THIS >> Make sure AC is unplugged, the battery is not connected yet and the unit is switched off! I bought the  Power Bright 2-AWG3 2 AWG Gauge 3-Foot Professional Series Inverter Cables  along this UPS originally and I still use them. However, what I did last month (April) was that I cut off one end of each of the cables and exposed about 1 to 2 inches of the cable. I then pushed the exposed portion of the cable into the UPS power holes and used an L wrench to tighten the cable as much as possible to the point where it no longer moves at all. This way the cable is secure and shouldn't fall out and is fully contacted in the UPS. Once done do not bother to remove it at all. Also if you look inside of the unit with a flashlight, you can see the same thing being done on the far end. So to recap, make sure you push the exposed copper cable in as far as it goes (should touch the far end) then tighten as far as it can go. << DO THIS >>The unit lacks the other dip switches so you may or may not be OK in your situation. So when the manual mentions the optional switches, sulk knowing you have no control and no way of knowing what the unit is doing, despite that, you could assume it uses the default settings.When the battery is fully charged and not inverting, it's pretty quiet although it makes a slight electrical hum noise. When the inverter is on, the unit buzzes quite loudly. When it's charging the fan turns on full blast and is noisy. it also clicks alot, sometimes at random.The "traffic light" interface is good. It works for the battery charge so you have an estimate of how much you got while the other indicators work well whether it's charging or inverting. The plug you see there is a standard RJ45 8P8C T568 (Ethernet cable) but do not plug it into your network otherwise you will fry the entire network. The plug is used for the "remote control" module, which varies depending on it's usefulness in your situation.But overall, the unit has performed well never being turned off for 6 months with no maintenence so far.However, here are some important tips:*) CAREFUL WHEN HOOKING UP THE BATTERIES, THE SPARKS FLY FAR!*) BE SURE THE CONNECTIONS ARE AS TIGHT AS YOU CAN MAKE IT, BECAUSE THE TERMINALS CAN GET HOT DUE TO LOOSE CONNECTIONS.*) USE LOWER NUMBERED AWG CABLES, THEY ARE THICKER AND ARE MUCH BETTER. ALTHOUGH THEY ARE EXPENSIVE, THEY PROBABLY WON'T INSTANTLY FRY.

I installed this as part of a solar electric system that powers some lights and freezers. It works great for that. Obviously not all the bells and whistles of a solar inverter and this is only modified sine wave not full sine. It works well for most things though. A couple of important points if someone was planning on using it for that purpose.1. This is modified sine wave. It will run motors and lights and smaller electrical appliances and older televisions even. It wont run newer TVs (I don't know what the cutoff age or technology is - it runs an old CRT type fine. It causes buzzing on a newer LED TV). It wont run UPSes, though it will run some computers and charge laptop batteries.2. It gives precedence to line power, not batteries. This is easily dealt with if you get a battery monitoring device (or if your charge controller can do it) that can send 12 volts to an auxiliary connection. Then get a solid state relay. You will either need normally open or normally closed. With an Outback 80 it has to be normally closed. Then you can set up an event that opens the relay, which is connected to your line input, when the battery's charge falls below a setpoint. You might be able to start a generator in the same way. I am going to try that soon.3. At the time I purchased this, Tripplite does not have the battery temperature sensor cable available for purchase. They advertise the functionality but you cant buy the cable. They assure me that it is due for release very soon but this inverter has been available for years so why would they not have the cable? Not major but not insignificant either...4. The documentation that comes with the inverter is pretty sparse. In particular, there is a low-amp charge setting and a high-amp charge setting. How may amps on each setting is not specified and the documentation on the web is inconsistent. I tested it and got 25 amps on low and 100 amps on high (DC amps). This concurs with SOME of the documentation on the web and what is now in the description here on Amazon.For 25% of the cost of the least expensive solar inverter, this will do the trick - at least until I upgrade to 24 volt battery banks and then I will likely spring for a higher watt Magnum or Outback inverter. I would recommend it if you need to cut some cost of a solar power system, at least based on how it has worked so far. Time will tell and I will update if there are early failures.

I have owned 3 of these TripLite inverters for over 8 years. They have been in continuous operation all that time. I am using them for a storm safety room, additionally powering my house security system and all the internet network. I have had actual power outages where these units have performed exactly as planned.

the unit performs well, but the fan is always on, even if no load or very little load is drawn. if the unit even just has a basic on/off function for the fan to keep it off when the unit is could i would have given it 4 stars. with an rpm controlled fan i would have given it 5 stars. it's just sad that they felt a need to save the 50 cents on the components necessary for a thermal fan control.

Compré el inversor con UPS para respaldo de equipo de video vigilancia de un fraccionamiento tengo conectado 3 DVR unas 25 cámaras, internet y una pantalla todo funciono bien llevo con el un mes y lo he probado 3 veces y sin ningún problema no se apagan el monitor ni los grabadores cuando se activa el UPS es robusto le conecte una batería de gel y recomiendo leer bien el instructivo para no tener problemas ya que tiene varias configuraciones.El nobreak solo me daba de 15 minutos las baterías se dañaban constantemente y ahora tengo 3 hrs de respaldo sin el monitor prendido. El único pero que le vi es que su onda senoidal no es pura.

Easy to set up. The plug space in the right could be wider and have more room for bigger plugs...I had to cut part of plastic side to make my plug fit. Works great! I wish I would of found this product sooner!

I paired this with a Marine (deep-cycle) AGM battery with a 92 AH capacity. Since I only need to keep my primary server and cable modem running during a power outage, this should give me about 3 hours+ of runtime. That should be more than enough to keep my domains available. There are some very expensive long-run UPS units out there, running into the thousands of dollars. There are relatively inexpensive units for the SOHO (small office/home office) market. But this unit represents a customizable and affordable solution for people like me. It also provides me the option to add more batteries (of the same type, of course) in parallel for even longer run times. So while the price might seem steep, it's actually an economical investment. After all, when you compare ten or twenty minutes of backup power to three hours plus...It's solidly-built and the manufacturer has a stellar reputation, well-earned. Very highly recommended!
