Power Inverter 1500Watt Pure Sine Wave Inverter 12V to 110V 120V AC with UL Fuses Compatible with Lithium Battery for Home RV Truck Off-Grid Solar with 15FT Battery Level Monitor Remote by VOLTWORKS

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 packaged2. I have tested it at 900 watts load and it holds that at 120v easily3. The fan is quiet and doesn't run that often especially under light loads4. 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.

Connected this 1500-watt (max run wattage) inverter to starting battery on Chev truck to provide AC power to small fridge and portable AC during power outage. Tested: inverter auto shut-off when battery dropped to low - but still enough power in battery to start the truck (nice). Ran inverter for couple of hours with truck running without issue. No problems with anything connected to inverter AC side - due to the pure sine wave output. Display on the inverter shows input and output power usage. Comes with a remote on/off with long connector cable that I did not test (used power switch on the inverter itself). Includes a good instruction manual and power cables to connect directly to a battery. Inverter's internal cooling fan not very loud when running. All in all, this inverter did very well and answered the call when needed.

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 I had this Inverter since June of 2023. It worked perfectly before. I only use this mainly for our overland truck and not using it heavily but just this month it stopped working. When I turn it on it just giving me continuous beeps. Thought it was over voltage from the battery but not. I tried draining my battery but still giving me continuous beeps. So I contacted Voltworks to see if my unit is under warranty and they said it already passed it but they're kind enough to send me a replacement. Huge thanks to Alice for an awesome customer service. Thank you so very much Alice!
