    5.0 out of 5 stars Very Good 1,500 Watt Pure Sine Wave Power Inverter for the Price, But Remember That They Do Not Have Much Surge Power Capacity!

    I own three of these Samlex PST-150S-12A 1500 watt pure sine wave (PSW) inverters, and two have been in continual 24-hour-per-day use in an off-grid battery backup power system for at least 4 years, while one remains in reserve as a spare/swap-out backup unit.

    BTW, as of sometime in 2015 or early 2016, this Samlex PST-150S-12A model has apparently been recently discontinued by Samlex, and replaced with a very-similar but slightly upgraded version with a model number of PST-1500-12. My current review, of course, is for the earlier/original Samlex PST-150S-12A model.

    Briefly, I love these inverters. I purchased them with full knowledge that they do not offer much reserve power / surge power capability beyond the 1,500 watt rated output (the surge power rating is stated as 3,000 watts surge, but for less than one second, which is not very forgiving...), and the two that are in 24-hour-per-day service perform perfectly, bearing in mind, of course, the earlier-mentioned fact that they are not designed to handle large load power surges. They even regularly provide power to heavy-duty power tools that draw 13 amps (at 120 VAC), and they handle these temporary heavy loads just fine.

    I have found these units to be very hardy and robust, with no failures of any kind. They are both in use in very rough and demanding service, in a sheltered but unheated control room where temperatures can range from -15 degrees F in winter to as high as 105 degrees F in summer, and with very high humidity levels at times, and they perform perfectly, each producing AC power 24 hours per day.

    The few times that I have accidentally tried to draw much more than the rated 1,500 watts of 120 VAC power from the inverter output, the inverter simply shuts down due to is overload-detection feature and sounds and audible alarm, at which point I walk out to the backup power control room and reset the unit by cycling the power switch.

    For the price, these are excellent pure sine wave inverters. Very tough and robust.

    I have had several inverters over the years, and the Samlex PST- 150S -12A 1500 Watt DC/AC Pure Sine Wave Inverter takes the cake. Not only was it economical for a 1500W pure sinewave inverter, but I have used it heavily every day for a year (It hasn't been turned off at all in fact) using 15A powertools, charging everything I can get my hands on, 52" Sony TV with subwoofer and surround sound, Nintendo Wi, large refridgerator and freezer for several hours a day, 1500W oil filled space heater, lights, 2 laptops, toaster, 1400W microwave, blender etc. In fact I am writing this review using solar power via the Samlex inverter.

    Important to know-

    *The inverter fan is quite noisy, but I went my first 2 months never hearing it. It seems to only kick-in when you run a product that consumes more than 600W for more than 30 minutes, even then its intermittent.

    *The positive and negative connection points from the battery are smaller than I would expect. They appear to support up to a 2 AWG wire, but not bigger than that. This shouldn't be a problem however since 2 AWG should be big enough for the maximum amperage this product can supply without turning off.

    *Some "Pure-Sine" inverters produce a buzzing noise or interference when used with certain products with tv or radio signals, interfere with cell phone signals, or cause brushed tools to run "funny" this one doesn't. In my opinion, it is the purest power you can get, probably better than the electrical grid supplies.

    I would recommend this inverter to my friends and family (And have several times)

    Update 4-29-13

    I have now had this unit for 3 years and it is still going strong. Still no problems, no signs of weakness, and unless its abused I can't see this ever refusing to do what you ask it to do. The list of things I have now used this for are endless. In conjunction with my 410w of solar and 4 deep cycle batteries it has done everything from provide power to my daily uses like run my laptop and tv, to run my coffee maker and everything else during 2 day power outages.

    In short, I have asked this 1500W inverter to do more than most people would ask it to do over the past 3 years and it has yet to fail me or show any signs of weakness. It still produces clean, reliable power... All at what still appears to be quite a bit cheaper than the competitors... I had never heard of Samlex prior to this purchase and due to my experience with this unit, they have my product loyalty which is a hard thing to achieve.
