BELTTT 2000W Pure Sine Wave Inverter, Inverter 12V DC to 120V AC for Solar, RV, Truck, Outdoor, Power Inverter with Dual AC and 20A Socket, 5V 2.1A USB, Surge 4000W, Hardwire Port, Remote Controller

Exceptionally well-built, without the number one cause of failure related to design flaw - using bolted wiring lugs. This one has proper soldered metal tabs that are securely soldered directly to the circuit board for the battery wires, which prevents high resistance in the battery input from developing as the lugs heat up and cool down, expanding and contacting until the internal connections where the wires bolt on the back of the lugs come loose and add massive amounts of resistance. This is what caused the fire that resulted inside my last inverter (you can find my review of that one with photos of the internal wiring that melted and caught fire in my other reviews here). The way the tabs on this inverter are soldered directly to the board instead of using knurled twist connectors like many others do relieves my fear of another fire. The battery cables bolt on with actual bolts to the exposed side of the tabs, and have hard plastic shells that prevent short circuits in the battery cables where they go into the converter housing. This is MUCH safer than the lugs with wires bolted on the inside that then connect to the circuit board. The display that comes on the face of this unit, and the one on the remote switch are clear, easy to read, and not so bright that they'll keep you awake at night. They also have useful information for quick-glance occasional checking of the battery voltage, AC output voltage and a bar graph for current load. They also show either "OK" when the system is functioning normally, and fault codes for errors such as over voltage, overload, and other possible faults. Intuitively, the face of both readouts has fault code explanations right on the panel so you'll never have to go looking through drawers trying to find the owner's manual to know what went wrong if you get an error, and can use the information immediately to correct the fault. This speaks very highly of the design. Installation was very easy, and due to the type of transformers this inverter uses, it's just over half the weight of many comparable inverters. One of the best things about this inverter is that when the red push-button switch on the face of the inverter (and the remote switch if connected) are in the "off" position, there is NO current draw, so you don't get the typical arcing that occurs with many of the inverters in this price range, and don't have to use a resistor when connecting your battery to prevent huge sparks. This is a huge safety bonus for lead acid battery setups as that spark could lead to an explosion if your battery is off-gassing when you make that connection. So far, I'm quite impressed. I tested the system using a 300ah lithium iron phosphate battery to power the inverter, and running a 10,000btu home air conditioner plugged directly into one of the inverter sockets. The inverter didn't even stumble, powering the air conditioner for over an hour. The fans turned on immediately when the load was applied, rather than waiting for the inverter to heat up, which again is safer than units which turn the fans on in response to heat after it occurs. This kept the heat on the outside of the inverter down to only 24f above ambient temperature. The fans are also about as noisy as an electric toothbrush, (and far less irritating). As for longevity, only time will tell. But we're off to a great start so far, and for the reasons already mentioned, I already feel confident that this inverter was designed to perform well, and to last. If anything changes, I'll change my review to reflect the changes. If you're reading this review and it's still showing 5 stars with no updates, it's still performing as stated.

My first impression of the inverter upon unboxing was that it felt a little "cheap". The extruded chassis is fine but the "end caps" are hard plastic which I suspect would break during an impact. That said.... I powered up the inverter. The output appears to be rock-steady under load. I no longer have an O-scope, so I can't attest to the quality of the waveform, but I can say that the load did not have even a hint of oscillation like I see with many other inverters. I used it to capacity test a 100Ah, 12V LFP battery at a constant load of 80 amps. Nothing magic about that load except that it happened to be what my test load was ( a small space heater.) The only thing I wish this inverter had was digital display of either input current, output current, or watts. It displays input VDC and output voltage, which is locked to 120V so that's a moot value to display. It does have a 5 segment bar graph display for "output power", but I would like to see that as a digital display. At very low loads, (such as running fans and lights), the cooling fans do not come on. At loads that are greater than 1 segment on the bar graph, the fans kick on. The fans are audibly noticeable, but not objectionable. There was no hint of the unit heating up at amps roughly 1kW constant load. The remote control panel is a great touch for my application so I can install the inverter out of sight and the control panel in my nav station with my other AC and DC breakers and meters. Overall, I'm impressed for the money. This should be more than adequate to run my microwave, coffee-maker, and other AC loads when I'm away from shore power.

I bought this inverter to use in my camper, and I'm glad I bought it, although now I'm wishing I had bought their 3000-Watt model so I could power more appliances like the coffee pot or vacuum cleaner. I will most likely buy that one and use this one in my truck in the near future. That said, It's an extremely well-built inverter for under $100. As it is, this inverter is great for smaller appliances and electronics. I've run my KOIOS air purifier with it, my laptop and TV with no issues. I've got it hooked up to a general lead-acid battery at the moment which is kept charged with two 100-watt solar panels, and it’s working fine. I had a partly-sunny day yesterday, and I used the inverter for several hours without depleting my battery. I really like the ease of installation and the high quality and workmanship that went into this inverter. The LED display is really nice, so you can see at a glance your DC input, power output, error codes and battery level. The power connection in the back is great, not those stupid knobs that other inverters have. These are bolts with nuts and washers that do a MUCH safer and more reliable job. I also like the included grounding block mounted on the side. To wrap up, the BELTTT brand is impressive. Well built, easy to install, functions well, is SUPER quiet, is mountable so it travels fine, and makes a great addition to my camper to use during power outages or just to help offset the electricity that I use with shore power hooked up to my camper. I wish I had gone ahead and bought the 3000-Watt model, but that’s on me. I recommend this product.

I’m very satisfied with the performance of the BELTTT 2000W Pure Sine Wave Inverter. It delivers reliable and stable power when converting 12V DC to 120V AC, making it a great solution for RVs, trucks, and off-grid use. The installation and operation are straightforward, and the unit feels very solid and well built. I especially appreciate the pure sine wave output, which provides clean and stable electricity that works safely with sensitive electronics such as laptops, TVs, and small appliances.

Works as advertised and has been tested to deliver a peak power surge of 6k. No noted issue on the one I received. HOWEVER, a friend also ordered one, and I planned to test it for them.....the connection posts were HIGHLY corroded and unusable. I highly recommend checking your device upon receipt.

This seems to be very efficient and makes me happy when drawing 200-300 watts the fans haven’t kicked on but with my heat gun the fans kick on instantly. With my gaming laptop load of 200-300w the unit stayed at or below 100f passively which is nice. With it on and no load has draw of around 12w and 1amp. Solid unit with nice features

Review of the 1.5 kW inverter I was able to burn it in for about 8 hours running off a 1120 AH Li battery bank powering a space heater. My kill-a-watt showed the heater was drawing 1.45 kW so this was definitely a stress test. It had no problems. 👍 The supplied wires are 25 mm^2 which is a little smaller than 3 AWG, they got a little warm during the run. For comparison in my motorhome the 2 kW inverter was wired from the factory with 2/0 AWG (67 mm^2). The indicated battery voltage on the inverter was ~.5 V below what my handheld DVM read, the AC voltage out reading was essentially the same as the kill-a-watt. The manual doesn’t say what type of battery the battery capacity bar graph is for, I’d venture a guess that it’s for flooded led acid and therefore not really useful for other battery chemistries. The bar graph for load level isn’t that useful, a numeric display of the load in watts would be much better. The bar graph was in the red for my run. Overall I’m pretty happy with the inverter so far and I’m impressed it was able to handle a load at essentially rated capacity for so long without letting the magic smoke escape.

True to prior reviews, this appears to be a well built and capable inverter that comes with everything you need. Hooked it up the day I got it and it's been powering a 5 cu ft chest freezer continuously, and other devices as needed without any issues for 48hrs now. Couple of minor things that potential buyers should be aware of, and the reason for 4 instead of 5 stars: 1 of the 2 plastic acorn nuts that secure the terminal protector caps wasn't fully threaded, so it can't engage the terminal lug unless you discard one of the 2 supplied flat washers. There was also no reading on the output meter on either the inverter screen or wired remote with my 60 watt test load, so I thought I had a defective unit. Saw a YT vid where the reviewer had the same issue, which is there will be no display on the output meter with "low" wattage loads. When I ran a load of 600 watts, the output meter did show 2 bars. Too bad they went with a bar, rather than a numerical output display. Overall, this inverter has done what I need it to so far- delivering continuous clean and stable a/c power without any issues.
