  I have 40 acres of Juniper out in the middle of nowhere completely off the electric grid. I run stuff with my own small solar system. I have had a Samlex 2kwe inverter for more that 10 years and it is starting to trip off under light load when it gets warm. I purchased this inverter to replace the current one. It is quite a bit bigger and heavier than my Samlex and, so far, works really well.

  The Good:

  1. Arrived quickly and well packaged

  2. I have tested it at 900 watts load and it holds that at 120v easily

  3. The fan is quiet and doesn't run that often especially under light loads

  4. Comes with a nice set of cables to connect to the battery bank. The listing doesn't mention the cables and I was surprised and glad to get them. A good cable set alone is $30.

  The Not So Good:

  1. The inverter comes with a meter that tells you when it is running and the state of charge of the battery it is connected to. You can also use the meter to turn the inverter on and off. If you are connecting this to a LiFePO4 battery the meter always tells you the battery is good because Lithium batteries don't have a voltage fall off like lead/acid batteries. Since I am using lithium batteries and it is just as easy to turn the inverter on at the inverter I don't use the meter. A meter that read output power either in watts or amps would be much more useful.

  The Not Verified - Longevity. I have only used this for a couple of weeks. It has been perfect since I installed it but how long it will last is unknown. I did not deduct a star for this. If I have an issue with the life of the inverter I will update this review.

  This has been updated after having for a few months for the 1,500W pure sine inverter. I have done some digging to try to get a better understanding of the nuances of this inverter. This in the USA market.

  Something to point out when I asked the brand label about using a bonding plug with this inverter is they recommend against it, claiming it could cause damage and be dangerous, instead referring to using a GFCI inverter. However, now I have spent some time in the NEC codes and ran some tests and the answer I have is this is a "floating neutral" "power generator". In the NEC code a "separately derived" generator must have a ground bonded neutral. For an inverter like this, you can do this via a bonding plug. It works. Now with the bonding plug the inverter is NEC compliant. The only reason you would not bond an inverter like this is if you are using it with a transfer switch (or other setup) where you know there is already a bonded ground neutral connection. All NEC compliant setups only have one bonding point, not zero, not two. So in the case of say mounting this in a car, it is a "separately derived" generator and thus must have the ground and neutral bonded in order to be NEC compliant. Another way to put it in simple terms is the manufacturer recommendation is more dangerous than conforming to NEC codes as you cannot clear a ground fault state without a ground-neutral bond, and this is why it is confusing to talk to them because they are telling you the wrong things. They don't actually understand how their products work and they certainly don't understand electrical codes in the USA. I have done some reading and have done some tests and the brand label for this inverter is just plain wrong. At least whoever engineered this inverter knew what they were doing and designed something that conforms to norms, at least for products coming out of China. It is just the brand label selling this inverter never talked to the engineer, so they have no idea what is going on. (If it generates AC power and is coming out of China, it is probably a "floating neutral" generator unless otherwise stated. Even if it claims to be bonded, you still have to hook an AC outlet tester to it to see if they lied to you.)

  One of my big goals with this inverter is to drive single phase AC motors. This works fine with this inverter, no buzzing. (MST inverters will cause motors to buzz and get super hot, so thus why pure sine is important.) Actually, you don't really use the whole 1,500W most of the time for this use case because most of this extra inverter capability is to just get one of these motors started and then handle the electrical noise from one of these rather primitive motors. An inverter closer to the rated power of one of these motors will get overwhelmed by the starting load and then electrical noise while in operation and shed the load. This inverter is doing the job without shedding the load, so success.

  So far it works like it should. Easy to install, and looks like it will last for a few years. It has 2 plugs and a terminal that allows for the addition of a larger 20 amp plug if needed.

  Everything is well thought out on this inverter and fits nicely in my work truck under my back seat. It allows me to charge my tool batteries without having to fire up my gas generator.

  So far the inverter fans have yet to turn on, perhaps in the summer time they will. However from my limited time with this inverter, it would appear that this inverter is fairly efficient.

  I'll update my review if it fails prematurely.

  This inverter seemed like a great inverter at first. It powers all my electronics in my 5th wheel until I turn on the microwave. Once it hits around 1500-1600 watts, it will turn off. It powers my coffee maker, TV, radio, lights, phone chargers, CPAP and computer just fine (Not all at once). It is super quiet and comes with some good wires and a super easy to use remote power button. I know Voltworks has great products but I suspect I received one of the few with a problem. Their customer service has been wonderful and timely with getting this problem resolved.

  I ran it for 3 days with a LIFEPO4 battery, with a small load(laptop/lights), and worked as expected. Barely warm. No fan noise as I did not put enough load on it. The remote gauge works but is not accurate. As soon as one green bar turns off, you would expect that you have 75% battery usage left, but wrong. You are it the last 10-20% of reserve (@~11 volts). No big deal but good to understand. Also, it allowed the battery voltage to drop too low, and my BMS kicked in, turning off the battery. Had to wait for the battery BMS to reset before I could but a charge on it. It was my choice to pay less and buy an inverter without a built-in gauge. And with a price reduction for father's day weekend, I ordered. I also tested with a 5 amps drill, on and off, and no issues with the sudden power demand ( was trying to simulate my cube freezer or frigo starting up). This inverter does not advertise if it can startup a large appliance or tools. I did not try any. Other inverters state they have a higher peak/surge capacity for inductive loads, which is a condition with a motor, A/C, or large power tool. Something to consider, or read up other comments in case folks have tried. Mine is the 1500W model.

  Been performing very well so far. Only been 2 weeks installed in my Semi. This is the 2000 watt version, which, realistically, is 1K more than I need. Fans can be a bit loud, but, so far they've only kicked on a few times and only ran 15-30 seconds. Use heavier cable than they provide, tho, their cables are way too small to handle this much power.

  Hardwired and works great in my motorhome

  I have the 2000-watt inverter, and it's great to have it hardwired into my primary 110v circuit on my Class C motorhome (with dual batteries and a 100-watt solar panel). Most of my 110-v outlets are therefore "live" when the inverter is on, allowing me to run electronic appliances without the generator while driving or boondocking. No problems with it yet, and it operated my 1100-watt coffee maker just fine while camping. As we crossed I-70 from Ohio to Utah, it was nice to have a couple of fans to blowing in the faces of the passengers sitting at the dinette. My wife even used her foot massager as we rambled on the interstate hour after hour. Such nice conveniences, and since the engine was charging the batteries as we drove, there's no issue with using up the batteries.

  I must compliment the Voltworks Customer Service Dept on their incredible service. Before I bought it, I sent them several questions by e-mail, and always got prompt and helpful responses. Once I received it, my questions increased because I was planning to install it myself. Always prompt responses. I ended up having a professional install it and hardwire it, but I still had questions about using it, and they continue to respond to all my questions.

  I am glad it has so many safeguards built in. The installers added a fuse between the battery source and inverter. It's located in a compartment under the bed with other electronics, so the installers added vents since the inverter can generate heat and needs to disperse it. Because it is hidden away, I don't have the advantage of seeing the display on the top of the unit, but I do have a battery voltage display on my solar controller panel.

  Keep in mind that this inverter is large and heavy -- 16" long, 8" wide, and 4" tall, and weighs almost 9 lbs. My installers had to beef up the wood panel where it was installed. The supplied 5AWG battery cables were okay for me since the distance to the power source was just 18" or so, but for longer runs, you will need heavier-duty cables.

  The remote on/off switch is convenient, and gives a general indication of battery status. With more experience, I plan to try higher-wattage appliances when necessary and learn how much the inverter can handle.

  This is a solid inverter and will fit my needs well in my motorhome. I am glad that whatever question arises, they fully answer me right away.

  No/non-functional safety features, shoddy construction, incredibly predatory warranty.

  Dear fellow review junkie, please listen to my tale of woe and learn from my mistakes: Don't cheap out on your inverter, get one from a -real- brand.

  I got the 3000 watt version. If you don't want to read this entire review, just know that I took this apart after it broke, and looked at the components inside. If you actually did try to run this at 3000 watts you will probably melt and/or vaporize something, and I'd be amazed if you didn't burn your house/shed/RV down.

  I practically never write reviews, but this company has, bar none, the most predatory "warranty return" policy I have ever seen, and that is what made me indignant enough to write out this novel. Steer very, very clear of anything this company makes unless you like living dangerously with no recourse in exchange for saving a couple hundred bucks.

  I got this inverter for my equipment shed, along with panels, a controller, and battery (fortunately not from this brand). The most I ever had running at one time was around 1000 watts, and mostly it was maybe 80 to run some lights. A lot of the time I just had the system shut off completely.

  Everything seemed fine for about 4 months, then last weekend I was working at the shed, only running the lights, and the inverter suddenly started sparking and smoking. I have no idea what specifically broke, but when I opened the case to see what I could see, the internal components are way, way too small for its claimed rating. 3000 watts at 12 volts is 250 amps. I don't know what gauge the wires are inside, but they absolutely are not even close to 4/0 AWG. I'd be surprised if they were even 8 gauge.

  I'm really happy I was there when it broke because even though it was visibly arcing and smoking, the unit apparently does not have any sort of monitoring since it did not shut itself off, and I had to turn it off myself. Several times previously I had left it on overnight to run a trickle charger - I can only imagine what would have happened if it had broken then.

  Voltworks' return policy is the most atrociously predatory thing I have ever seen, and I've bought a lot of stuff from a lot of dodgy resellers like this one. If you try to do a warranty return, and they "determine" that the problem was not their fault, not only will you have to eat the cost of shipping it back to them, they will also attempt to ship the broken unit back to you and charge you to do it! So you'd be out 50 bucks (per FedEx's calculator) to ship it to them, and then they'd try to fleece you for another 50 bucks when they inevitably decide that their inadequate construction was your fault.

  I know it's cliché to say this, but I'd rate this zero stars if I could. I think it's justified given that it did its level best to burn down my shed and the expensive equipment inside (and I know this is partially on me for not appreciating the potential consequences - lesson definitely learned there). Blatantly false advertising on its capacity, shoddy construction, no safety features whatsoever on a high-power electrical component, and a stupidly predatory return policy. It's hard to overstate just how unbelievably bad this is.

  If you're going to try and cheap out on your solar power setup, you really, really don't want to do it with the inverter. I got a new one delivered just today from a REAL brand, and even though it's only rated for 2000 watts, it weighs noticeably more than Voltworks' "3000 watt" one. That's all you need to know.
