    • Perfect for my 12 volt solar setup
Size: 300 Watt Style: Wave Inverter
Review Image by EarthLaunch EarthLaunch
Review Image by EarthLaunch EarthLaunch
I have a 12-volt solar panel system installed in my car, including batteries. Roof space for panels is limited, so efficiency is important; MPPT charge controller, thick gauge wiring, and this inverter. From this inverter I run a long extension cord to my tent where I power my work gear; monitors, laptop, and cell phone, totaling between 30-200 watts. I also use it for a small electric blanket (150 watt) if I'm up late in the cold. It works perfectly, and being pure sine is safe for my computer stuff. Note that I usually do not ground this system and it works fine (not that I'm recommending this). Inverters have a peak efficiency which is at around 50% load. If you look at the specifications of this on their site, it says peak efficiency is 90% at 50% load. You can also Google "inverter efficiency curve" to see how it works. Generally you want to be between 40-80% load. That's why to get a smaller inverter. I chose 300 watt because it fits my average usage profile perfectly. At about 100 watts average draw, this inverter's fan doesn't even need to run, which is exactly what I wanted. It's pretty quiet and cool. Pictures are of the inverter wired into my setup. Edit: I got my car stuck in 4 feet of snow (oops) and, in a rush to evacuate all my solar gear, I tore off the flat end of this inverter's included battery cable. I emailed Samlex, this is almost a year after purchase, asking if they could send a replacement cable. The next business day they had sent me one for free. I'm impressed and will be targeting Samlex for future purchases like this. 2024 edit: This thing is an absolute beast, it's still chugging along a decade later. I've used it on two vehicles and a boat. In one application, I was drawing 350-400 watts regularly, and this handled above-capacity just fine. One time, I did something to fry it, and I learned that it has standard, easy to replace fuses inside, which I easily replaced on the road. Amazing. As I said in my review, I've bought a bunch of other Samlex stuff like the EVO-1212F, and it all performs this well and handles tons of abuse. ... show more

    • Samlex 12 volt 300W with 120 volts continuous pure sine output
This pure sine inverter is quiet and only makes a peep when turning the switch on. Be sure to fire up any inverter a few seconds before plugging any load into it, that way you will avoid potential damage. We have run a 91 rated watts Bernina sewing machine with built in sewing light and a swing arm 40 watt incandescent light at the same time. There was no sound from the inverter as the fan didn't need to come on. The Samlex operators manual says to use AWG #8 for a 12v 3ft power input cable, #6 for a 6ft run and #4 for a 10ft run. Standard procedure with inverters is to limit voltage drop at 2% from battery bank to inverter input. This will give the 300 watt inverter safe input operating voltage and long life especially at full output or during the occasional short duration surge demand event. Included cable with battery clamps are for medium use, while the cable for the 12 volt lighter socket is probably good for approximately 100 watts of ac output, depending on vehicle wire and fuse size feeding the outlet. To be sure of powering a laptop computer, the inverter 12v input should be hard wired with the recommended copper cable, as some laptops may draw in excess of 100 watts. We plan to use this inverter in our travel trailer where it will power a 250 watt crock pot when we are driving down the road. This is a very good inverter, and that is why we bought it. For the microwave etc., we plan to eventually add a 2000 watt pure sine wave unit combined with built in battery charger. It is good to have two, as the smaller one can be portable, while a larger one should be more permanently installed. Our first inverter, & very happy with this Samlex. ... show more

    • Solid unit inspires confidence
Size: 300 Watt Style: Wave Inverter
I've just finished a permanent install of the PST-300-12 pure sine wave inverter, in my camper van. I'll say a few words about the install... will comment on function in the future, if anything unexpected comes up. I think the unit is well made. One design problem is that the screw slots in the mounting base do not extend far enough to the sides... which means that, when you go to screw the unit down, you'll have a hard time turning the screws with a screwdriver... and, when you do, the screwdriver will abrade the paint finish of the case. The cable terminals on the rear are unusual. You can use the provided cables (12 and 14 AWG, with clamp and 12v socket ends) to run up to 150 watt equipment. Those cables have blade terminals, which are available for cable as large as 10 AWG. If you do a permanent install, and want to use the full 300 watts available, you have to use 4, 6, or 8 AWG cable, depending on distance of inverter from battery. Those larger cable sizes require pin terminals, which are hard to find! I was pretty bummed, so, I contacted Samlex customer support. Customer support provided a link to FerrulesDirect, where one would have to buy 25 or 50 pin terminals in the larger cable sizes. The Samlex support guy also offered to send me a couple of the pin terminals I would need for 6 AWG. Huzzah! That's good support. Which it ought to be, since they chose such oddball connectors for their product. The pin terminals I received are actually PTNB10-12, for 8 AWG, shown on the FerrulesDirect page. They did just fit 6 AWG. That's good, because I note from the specs that the pin terminals for 6 AWG and 4 AWG show them to be too fat to fit into the 5mm receptacles on the inverter. I'm not sure what one would do to connect 4 AWG... it may be possible to use the terminals made for 6 AWG, and file down the 5.5mm pins, so they would fit the receptacles. The preferred solution would be to keep distance from battery to inverter at no more than 6 feet, so that 4 AWG would not be needed. The Samlex manual is very detailed, and not too difficult to read. Like the overall build, the manual inspires confidence in the product, and, I expect that this inverter will serve me well. ... show more

    • Can easily Fail. Buy a better rated inverter.
Size: 300 Watt Style: Wave Inverter
A complete failure. Left the unit seeing 1 or 2 watts, went on vacation for 2 months; returned to a completely DEAD 300 watt pure Sign Inverter. Unfortunately out of warantee.
