Samlex SSW-1500-12A SSW Series Pure Sine Wave Inverter - 1500 Watt

This is my second time I've purchased this inverter. My first purchase was for my last RV camper which we just sold.I really enjoyed having the ability to use my microwave, TV, and other items at night while camping without having to run the generator.However, I did not enjoy the fact that this inverter would run the fans continuously even with a 25 watt TV load!I resolved to fix this problem with my second purchase for my new camper and here is how I did it.Steps: (1) Purchase 2 thermostat switch for each fan (a) Switch 1 turns on at 100 deg F and turns off at 85 deg F If you use the following switch, you'll need to flatten the terminals parallel to the heat sink. http://www.amazon.com/Thermostat-Switch-Circuit-100%C2%B0F-Flange/dp/B0026RYU4W/ref=sr_1_2?ie=UTF8&qid=1365826213&sr=8-2&keywords=thermo+switch (b) Switch 2 turns on at 120 deg F and turns off at 105 deg F http://www.amazon.com/Thermostat-Switch-Circuit-120%C2%B0F-Flange/dp/B0026RTEZC/ref=sr_1_6?ie=UTF8&qid=1365826213&sr=8-6&keywords=thermo+switch (2) Dissassmble inverter (there are 4 sheet metal screws on the front faceplat and 4 on rear faceplate) (a) remove ground wire to bottom slide panel of inverter (b) remove ground wire to side of upper box panel of inverter (c) Slide everything apart (3) Using sheet metal screws or threaded screws with washers and nuts, mount one thermoswitch on each side of heat sink. There is plenty of room for the thermoswitches but test fit to make sure you can put things back together. (4) Cut/Splice the red wire from each double wire running to each fan to a lug of its respectively installed thermoswitch and solder. Use a hot glue gun to support the thin wire soldered to each thermoswitch lug. (5) Heat shrink, glue, tape, ziptie wiring as necessary to secure it. Ensure wire "heat shield tubing" is still protecting run of wire to each thermostwitch. (6) Reinstall ensuring nothing gets pinched or shorted. Don't forget to reinstall the two ground wires to the bottom and top (side) case components. (7) Marvel at your work and enjoy a nice quiet inverter whose fans don't turn on with small loads such an LCD tv in your RV camper without having to hear two fans running continuously!Options: With things apart, replace fans with quiet units. The fans dont bother me when they are running when needed. They move air and moving air makes noise. However, a 1500 watt inverter won't get hot when you are running loads less than 200 watts and having two fans run at this power output level are unnecessary in my opinion. If you want, you can only install a thermocouple for one fan if you need an extra buffer of "safety"Enjoy and I hope this tip helps others. Contact me if you wish for me to do this modification for you or need help.

I've had this inverter in service on my Freightliner 18 wheeler for about a month now. Overall I'm quite pleased; it handles my small refrigerator/freezer on the truck, and also a small 700 Watt Sharp microwave. I have no abnormal operations with any items I've plugged into it, which is as I hoped, and why I spent the extra money for the full sine wave inverter.My company insists on installing inverters on the trucks (if a driver buys one). The problem is that they have a one-size-fits-all approach to installing inverters. In my case they under-spec'd the wiring from the batteries to the inverter, with a 10 foot run of 4-gauge wire. Spec calls for no more than 4 feet of 2-gauge if I recall. Happy to say it is doing just fine with the setup as is.

This seems like a pretty good inverter. It had it's trial by fire about two weeks ago when there was a "blue sky outage" at my place. It ran my chest freezer and refrigerator with no problem at all. The fans are pretty loud as others have said, but I can live with it. It ran my appliances for about 2.5 hours before I got a low battery alarm. I hadn't charged those batteries in a few weeks, so maybe it will go longer with the charge topped off. I'm going to run a test with an oscilloscope at work to see exactly what the output voltage waveform looks like. I will post a "scope shot" here once I have it. The only minor complaint is that the input power studs are a strange size. They are 9mm metric. I can't find spare nuts that size anywhere, not even online. If you loose the hex nuts from the input terminals, you're screwed. You'll probably have to order them from the company at what I sure will be a significant mark-up.

So far it has performed great, i have it on my emergency solar box an needed it twice for power outages in the last month im not looking to test it to the max, but it easily ran my 48 in flat screen, a pair of 60 watt lights, two amps for my antenna and my wireless router, for three hours, all low wattage stuff, the only thing is when the second fan kicks on its pretty loud, not bad but louder than most I've had, sounds like it moves lots of cooling air

PROS:- Seems well made- Control panel is handyCONS:- The user guide mentioned the inverter could not be connected to circuits where neutral is connected or shared with ground. Even after isolating a circuit with separate hot, neutral, and ground connections the GFCI outlet trips if connected to an AC panel. An old MSW inverter did not shut off, this one does (and I know how to connect it)- The fans are really LOUD, uncertain of the power drain they cause but there are two 80mm fans- the fans turn on at 50w (in my basement in late winter, chassis and air temp is cold, about 55-60deg)- The unit I just received has a mfr date of 1/2011 (14 months old before even using it, perhaps it is a slow seller)VIDEO of fan noise:[...]

I have been using this for about a year. I currently use it to power my outside lighting which is comprised of LED lighting.I have use a modified inverter; however, the modified inverter causes a flicker in certain brands of LED bulbs. This pure sign wave inverter does not make any of my LED bulbs flicker.I would have given it five stars; however, the cost was about $350 which seemed high, and the fan seems noisy and comes on with only 30 watts of load or so.

It gave about 4-5 yrs good of service before negative wire touched case, which burnt it out. Hard connect heavy duty (thick 2/0) wire to posts.

Junk. First unit failed before any load was put on it. A real pain to return as company in in Vancouver, BC and customs forms need to be found and filled out. Shipping there seemed to take forever. Second unit would not even turn on, Not worth the time to try to get money back as I would have had to go through the whole customs and long wait time till they even got it.
