1500W Pure Sine Wave Inverter 12V DC to 120V AC Converter with LCD Remote

I am used to expensive marine grade inverters that produce a real pure sine wave. So i was not expecting a huge amount from these, as the price is 1/10th of the units i am used to. The units i am used to have been working away 24/7 for over 20 years with no issues, a tough act to follow. I got 3 of these for a house project, all 3 arrived properly packed. I unpacked and tested all 3, they all worked perfectly, no issues. Setup is easy, as would be expected, the hardwire connections are not really industrial grade, but they are adequate (barely). The remote is nice, easy to read in daylight or night. The battery percentage is not calibrated for LiFePo4 batteries, so do not use it to give you an accurate SOC status. But in truth you should never use the inverter to give you that data, you must get it from the battery itself, as the inverter will measure line voltage including the drop due to its own load. Use a Victron battery monitor or similar. I ramped up testing on each unit, from light loads to full bore, in incremental steps. Up to about 1200w it produces 120VAC from 1200 to 3800w it produces a clean and steady 118VAC 60hz. I have seen reviews where there were complaints that the voltage dropped below 110VAC on medium to high loads. My units worked as expected, but you must use suitable DC cables to power the unit. I tossed the DC cables that were provided in the box, they were worthless. I used properly made short run 2/0 AWG marine cables to power them, If the run was longer (>6ft) i would use 4/0 cables instead. The fan is fairly noisy, only has 2 speeds on and off. A variable speed fan would be a much better solution and would have added about 10 cents to the build cost. The fan came on around 1500w for my tests, but it would depend on the ambient temp for each case. As i planned to have these in a separate equipment room, the fan noise is not an issue. There is a slight delay ramping up the output power, but nothing i tested (heaters, induction cooktops, hair drier, tools, etc) complained or failed to work correctly. The delay you see on is just in the display updates, rather than the power itself. I put an oscilloscope on one of the output ports when it was producing 3000w of power, the sine wave is still clean. As someone else mentioned there is a tiny amount of top wave clipping, but the waveform is sufficiently clean to power everything i tested. I do not plan on using these for computers etc, for that i installed a Xantrex Prosine2.0, cost far more than all 3 of these, but i know they are totally clean waveforms. The waveform on these inverters is actually better than the Honda EU2000/EU2200/EU3000 generators. I cannot speak to the longevity of these inverters. If i find failures or issues down the road, i will update this review accordingly. So far i am very happy with them.

I don’t write reviews often This inverter and I have had a great first impression O yea it switched from city to back up and back seamlessly for my (back up battery for pellet stove diy project) Yes it is pure sign wave Yes it switches fast with out interference and yes it had a neutral to ground bond auto switching relay so no floating neutral This review is based on temporary test to see if unit would work After full installation and some real life scenarios I will update

I can't say enough good things about this 48v Zetawale inverter. I bought two so that I can supply a 220v panel and added a Victron 48v charge controller. All three units worked the first time I turned them on! Now I have a 220v panel with 2500 watts on each leg. Each unit has a screen to tell the battery charge and usage. If you are thinking eg4, skip the headache and buy this Zetawale inverter. I can't say how long it will last but it sure is good to have a system work the day you install it.

Purchased the 1.5kw to replace a 1kw inverter that ran just about everything in my RV EXCEPT the 900w microwave. The remote control is the only issue I have with it it's quite thick for mounting in the relatively thin RV walls. I may gut it and make a flatter, surface mount remote control.. If they produced a Bluetooth + app controller I would buy it in a heartbeat! I do wish the display showed AC watts, but for now I do the calculations. The biggest reason I chose this unit was the wired AC out connection! I have a 3 input transfer switch (Shore, Generator, Inverter). The hard wire leaves the 4 outlets on the unit available (but I don't use now that the transfer Switch takes care of that). My Coleman Mach classic runs great on the inverter! So does the microwave & coffee maker BUT NOT At The Same Time!!! It handled starting inductive loads with ease. I suggest increasing the size and type of the DC cable. I needed 1m to reach the battery. I used 4 gauge pure copper tinned wire. The voltage drop across the wire at full load is <.4v, much better than the wire that came with it. Don't use Aluminum copper clad cable. It is prone to corrosion and failure at the connectors. Yes aluminum is less expensive but...

I bought one of these about six months ago for my RV. It works flawlessly. I can run the microwave while my wife uses her hair drier. It recently failed for no reason I could identify, so I e-mailed customer service late in the day Saturday 9/5/26. Based on previous experiences with many other vendors, I was prepared for a contentious and time consuming process. I got a response within 12 hours! They asked a couple of basic technical questions, and I was asked to provide my purchase invoice and to run a basic test. I responded but forgot to attach the jpegs, but I got a response Sunday, indicating that they were shipping me a new unit immediately, but could I send the jpegs requested? (I did, of course). I just got the new unit today, Tuesday 9/8/26. This is a very good company! Customer service that others should emulate.

Only a couple of issues and neither is worth losing a Star for. My unit arrived without any sort of manual in the box, packaging was clearly a new unit, simply missing any sort of paperwork. No problem, went to the makers website; ooops no manual online BUT an easy to find contact and got a great response same day - now that's awesome service! I've set up enough of this type of unit that a manual wasn't critical for operation, very self explanatory BUT another brand I have in another building does NOT allow you to mount vertically. Simply inquired of the maker and YES you can mount this vertically. I had two reasons, simply a better fit in my location of choice and most important, it has two very nice cooling fans but for low power usage I want convection to carry moderate heat and save on a tiny bit of power when appropriate --- this 48v 4000w unit will need the fans facing the ceiling to achieve this minor detail. The one item I might drop a star on but won't; at my age of worn out joints, lol, the hardwire AC out is VERY inconvenient to access. It's NOT standing on my head that is the issue, it is tilted back toward the mounting board thus must bend the wires going in to the absolute perfect angle and it's so close to the mounting board that you have to feel around to get the wires in place prior to tightening the screws. This design could definitely use some work but hey, done right, it's only a one time endeavor. So far it's performing precisely as expected but I will note that I have not yet put a major long load on it. I did throw an 80 volt chainsaw battery on the charger, a 13.5 amp power saw and a 6.7 amp hammer drill on it simultaneously for a full minute and the inverter had no issues at all. Granted the cooling fans engaged but it never waivered.

Excellent inverter. Constant Ac 120 volts. No strange noise coming out of the inverter.

These Inverters work beautifully & Zetawale stands by them 100%. My Unit Broke within the Warranty Period & Zetawale responded quickly & replaced my unit & really went out of their way to make sure I was Satisfied. I Love These Inverters & This Company and I Highly Recommend Them, Check out my Pet Power Station featuring my Zetawale 1500W Inverter & 300AH Lifepo4 Battery on a Rolling Platform. I Love This Project & It Works Really, Really Good.

Hasta ahora cumple bien

El inversor se ve de buena calidad. Lo utilice en el rancho para alimentar al modem y antena Starlink cuando la energia electrica de la red se va (lo que ocurre seguido). Este inversor funciono perfectamente con mis baterias a 12V que se cargan con un panel solar. Aunque el consumo del sistema Starlink es pequeño, con otros inversores el modem hacia ruidos extraños. Pienso porque no le daban una onda sinusoidal pura similar a la del servicio eléctrico de CFE. Con este inversor trabajo perfectamente y la idea de adquirir el de 2000 watts es porque quiero alimentar toda la casa con el. Su modulo emoto de monitoreo es un plus. Lo único que no me gusto es que los cables que conectan a la bateria son muy cortos y tengo que adquirir o fabricar unos mas largos.

Trabajando excelente, le da abasto a toda la cabaña

Exelente

Es un buen producto si pueden cambiar los cables originales por más gruesos mejor, funciona
