BELTTT 2000W Pure Sine Wave Inverter for RV, Truck, and Solar Power Systems

Amazing inverter

Awesome inverter works great. In my 27 Freightliner cascadia. Mounted it under the bunk. Because it's got the remote. Keynote in order for the remote to work! You have to have the inverter powered off from the main power button on front of the inverter. Then turn it on with the switch and it will work. Also the voltage reading on the front of the inverter and the remote is dead on accurate! Compared to the voltage reading on my dashboard from the factory voltmeter. Way nicer and way cheaper than anything I could buy at a truck stop! Definitely would buy again but I'm not going to have to I don't think very high quality very well built

Great service after the sale.

My two brother n laws both have the Belttt 2000W Inverter in their RVs so I purchased one for mine to replace my rv refrigerator but had a problem with the inverter voltage reading incorrectly high, this keeps the inverter safety circuit from allowing the inverter to work, reached out to Beltt sent video ( as requested by Beltt) showing my input voltage was 14.3, inverter read out showed 16.2. Things happen but it’s how it’s handled are that makes the difference.

Decent, hard for it to supply startup surge

hard for it to supply startup surge with fridges/shop vacs Even with 800 ah in batteries backing it

Easy Install, full featured remote, easily powers Microwave and other appliances.

Bought this to replace an older 2KW inverter that was 7 years old. This was an easy install as all of the cabling was already in, only had to pull the remote as it used a different cable. This unit pulls 2.5 amps on startup but as soon as the capacitors are charged it drops back to 1 amp. My 1200 watt microwave pulls 140 amps and works perfectly, as does the Instant or crock pot. Wife likes that she can use her blow dryer and the like without issue. Highly recommend 200+ amp Lithium Batteries or Marine deep cycle at the least, I have 400 amp/hr so no power issues.

Very reliable

I’ve been using the BELTTT 3000W Pure Sine Wave Inverter in my semi truck, and it has been a great investment. I use it every day to power my appliances while I’m on the road, including my microwave, coffee maker, laptop, and phone chargers, and it has handled everything without any issues.

The pure sine wave output provides clean, stable power, so I don’t have to worry about my electronics. Installation was straightforward, and the included remote controller with the long cable makes it very convenient to turn the inverter on and off from inside the cab.

I also like that it has multiple power options with AC outlets, a USB port, and the hardwire connection. The cooling fans keep it running reliably, and it has performed well during long trips.

If you’re a truck driver looking for a dependable inverter to power your appliances on the road, I definitely recommend this one. It’s powerful, reliable, and has made life in my truck much more comfortable.

Power & convenience priced well

I purchased this Inverter to assist in building of my own Power Station. Inverter arrived on schedule and was packaged & protected very well for shipment. After installation and testing on my DIY Power Station, I am very satisfied with its output and operation. My PS setup will run ALL of my major appliances. Refrigerator, Freezer, Microwave, Washing Machine, Insta-Pot and any other household device that the imagination can render. (NOT ALL AT ONE TIME, of course. Have to stay within the "limits" of the Inverter) But this Inverter performed fantastic. I tend to use it mainly at night, during power outages, so I can keep my generator locked away from thieves. Priced very well, I highly recommend it for anyone in need of a powerful "limited" reliable alternative to long extension cords bundled everywhere and loud generators running in the background.

Great inverter, works as advertised with one caution.

I needed to replace a 600 watt modified sine wave inverter because my lights were starting to flicker due to the dirty sine wave. My lights are now solid because of this pure sine wave. I've tested up to 860 watts (shop vac) for a short period of time and worked fine including the fan. Otherwise I consistently use anywhere from 15 - 100 watts continuously with no issues and fan does not even come on for wattage that low.

Came preset to run at 120 volts and seems to maintain voltage between 119 and 120 based on load size. Battery voltage on display matches voltage on my charge controller exactly so I'll take that as a good sign of being accurate.

I'm going with 4 stars because as others have noted, the wires are not thick enough for very high, continuous loads. I would estimate you can safely run up to maybe 800 watts continuously with the wire gauge size provided. If you consistently run in the 900-1000 watt range, you will melt these wires for sure. A lot of inverters on the market seem to skimp on the wire size, guess it's all about cost cutting

So far, excellent value.

vrey good

Power up

This inverter works great for my off grid power at my shack. Thanks

Well made and works perfect, can't beat the price

Great inverter, compact size, fan only runs when it needs to, display gives very useful information. I added on the remote display for even more versatility. For my install I tucked it under the driver seat of a Polaris side by side using some standoffs and crafting some other parts. It turned out great and was just what I needed so that I could have AC electricity out in the field without carrying around a gas generator. It's enough to run a work lights, drills, pretty much anything I need. Impressive value for the price.

Great inverter for price.

So far so good. Worked as expected.

Worth the investment

This is an essential item that have to protect electrical components in appliances. We use this in conjunction with 12v lithium ion batteries when there is power outages.

We have used other type of inverters, but risked damaging our appliances because of the non-consistent energy waves.

This is a small investment, for a great peace of mind.

Adjustable output voltage!

This has an adjustment on the front panel for the output voltage, which is a great feature I haven’t seen in any other inverter.

In North America it comes set at 120V, but using the recessed momentary switch you can adjust the voltage up or down in 5V increments between 100 and 130V. The setting is persistent after three seconds.

The display shows the actual voltage rounded to the nearest integer.

The two single speed fans are a little whiny but not too annoying, probably about 38dba. This shouldn’t bother the neighbors at night, but I wouldn’t want to sit next to it for more than 5 minutes.

At 85F ambient and a load of 450 watts or lower, the fans are off. Anything above that they generally run continuously.

From all indications this produces a good sine wave output. Our ceiling fans don’t buzz with this, whereas they do with a modified sine inverter.

This obviously has active output voltage control since it is adjustable, so it can keep your set voltage under various loads. However it will hunt when large loads like a coffee maker or microwave are switched on and off, so your lights will get brighter and dimmer in about half second increments when those loads switch. Not too unlike any small generator or inverter, just a little different since it can both overshoot and undershoot for a half second at a time.

It comes with a remote display with an inverter on/off switch and a 35 ft 6 conductor RJ-11 cable for it. The display uses a serial protocol over the cable, and pins 3 and 4 are VCC and a normally open power switch pin called VIC. All 6 conductors are used.

The remote display duplicates the on-unit display, except it seems the remote doesn’t show the correct state of the ‘enhanced’ mode setting, it always shows ‘enhanced’.

Enhanced mode apparently lets the voltage sag more before shutting down under high loads, whereas in normal mode a shutdown is triggered with less voltage sag. The default is enhanced (Carrying capacity boost) mode.

I couple this with a 2kVA Yinleader voltage converter (autotransformer) to also produce nominal 240V to run my HVAC blower. I keep this set at 125V since I have a good amount of voltage drop through the transformer. I’ve tried and haven’t yet found a reliable 12V to 240V inverter.

Update: This has run reliably for about 16 hours so far under a continuous 1kW load.

Making a beeping sound ?why ?

It makes a beeping sound i cant figure out do you think i need to install the ground over all its nice but thats the only issue im dealing with can anyone explain why its making that noice

Very nice unit haven’t had any issues and I’ve tried a few

Very nice design small compact, easy screen to read makes no noise very compatible with a lot of systems. Best Bang 💥💥 for your buck

Decent quality and works pretty good so far 🍻

Replaced the failed factory 400w unit in my 2015 F150, with a little modification it sits perfect in the factory location .

Added an aftermarket 150A main fuse just in case .

Works fine for few small stuff I used on it so far 🍻

For RV owners

FOR RV OWNERS: I chose this inverter from the ratings and although I had a rough start, it all ended up great. When it was installed, the tech put a 300amp breaker on. But every time it would trip within 30 seconds of starting the microwave or espresso machine. I started asking around and got varied opinions. Most said I needed to replace this 3KW unit for a 6KW. But my calculations were as follows. Note that I wasnt expecting to run any of the below simultaneously; for instance I wanted to fix a cup of coffee, then toast, followed by a warmed up danish. So the draw at any given time, with a 10% buffer included, would only be half of the capacity of this 3kw inverter.

Espresso machine: 1300w

Toaster: 1200w

Microwave: 1300w.

Again, each appliance by itself was half of the rated capacity of this inverter. But again, it tripped the breaker every time. I finally contacted the manufacturer and they told me this unit has overload protection built-in. So I removed the 300amp breaker and now it works great. So if all you want is to fix a cup of coffee OR run the microwave OR fix toast, then this unit it ideal. If you want full AC comfort and all appliances at all times, then you’ll need to do the arithmetic and size your unit accordingly.

Lasted 2 weeks under almost no load

This seems like a pretty good inverter… until you use it for a while.

We have to pump water for our animals and I needed something to power our small 1A garden hose pump. The first weeks were great, but then it just stopped. When we turn in the inverter everything shows good, but any time we plug something in it we get a low battery fault(even though we’re connected to a new battery with an alternator running it).

Maybe we just got a lemon, but it’s really sad that this inverter ended up just not working at all after a couple weeks of use. The features looked great, but unfortunately I never got a chance to actually use them

Great inverter for the price. I will definitely recommend it.

This unit deserves it's 5 star rating.

The 1000w inverter works as described in the add. Fan noise is very acceptable at least in my garage. I purchased it to perform load testing on 12v lifepo4 batteries. I also use a fan forced 2 temperature heater 750w and 1500w for testing.

The 1500w maxes out the input amps at 78 amps at 12.0v I ran this setting for about 60 minutes on my new Weize 12v 100ah battery.

Then I turned it down to the lower setting and the input amps was 53.

With an infrared temperature gun the inverter stayed below 90⁰f. The cable temperature did reach 101⁰f under full load. There's also a small voltage drop of 0.18v on each supplied which isn't terrible.

Specs I verified maximum input amps was 92 at about 11.5v and it didn't give any high current warning. The low voltage beeper started at 11v and the unit did cut off at 9.5v at the ternimals on the back of the unit.

The display worked well and voltages were correct.

The only negative I found is the manual says the fuse won't blow unless it's incorrectly connected. New fuses are supplied but no instructions on replacing it.

If you are on the fence about purchasing don't think twice.

Not that good.

It turns off and on. I checked all my cables and everything seems snug and nothing is loose. The panel does not turn it off or on. You have to reset it at the inverter. It’s light and it has a couple of fans but won’t stay on while driving.

Keep it in open area in vehicle

Works good just need at least 2 batteries to get the full power out of it

A winner!!

After trying two other inverters from well known brands that would not satisfactorily run my ice maker, finally found this one that will!!

I have a U-Line ice maker in my camper which draws about 200 watts but not really sure what the inrush current (LRA) is but couldn't be more than 1000 watts. The two previous inverters almost always wanted to trip out on overload. I added an additional battery thinking maybe not enough current. Two 100ah lithium batteries in parallel didn't solve the problem.

Ran across this on a special and thought what's another $100 which at that price point wasn't expecting a whole lot but was I mistaken. It isn't as physically large as the previous two, but seems well constructed, the DC power terminals are heavy duty. So hooked it up and low and behold, powered up the ice maker with NO issues. I was impressed to say the least!

I do like the display showing voltage in and out. There is a bar graph showing the percentage of load. Wish there was an actual number showing the watts being used. The fan doesn't come on hardly at all at the load level I'm using it at. I'm sure if you were drawing down say 500+ watts it would run considerably more. Where I have the unit placed fan noise isn't really an issue.

Overall, very pleased with the performance at handling inductive loads. Only time will tell with durability and longevity but its off to a great start.

The Beast

Amazing i have it setup in my travel trailer every thing works great lights tv microwave and my air conditioner pulling almost 2300 watt no problem at all , you have to be careful with voltage drop to get all the power it need to stay next to the battery (short cable run ) , we drycamp at beach in mexico kids had tv and ps4 running all night on it no problem at all we call this inverter The Beast .

I like the digital display and wired remote control also with display as well.

It works as advertised. The thing I like is the Voltage stays close to 120 volt on 2000 watts load. And lastly the price was pretty good for a pure sine inverter.

This powerful deal!

WOW, I’m impressed! It met all specs, 3000 Watts continuous AND 6000 Watts inrush. I did a full evaluation. Beautiful sine wave, not just at idle but also at full load (shown in picture). I tried circular saws, angle grinders, shop vacs and space heaters, right up to 288 DC amps input continuous with 25.38 amps at 119 vac out = 3020 watts!

Fans come on when load increases and not overly noisy, less than 50 db @ 1 foot 19.9khz. Fan won’t come on immediately below 500 watts or until it gets hot. At 250 watts the fan may never need to turn on. An electric blanket or T.V. Probably won’t start the fan. The fans being on should be a subtle reminder that you are pulling power and using your battery. More specs; Weight less than TEN POUND! Frequency at idle 59.9 Hz and at full load 59.8 Hz. Idle current 24Watts or 1.8 amps. Indicated DC voltage is actually .050 lower than actual. Use a tie straps to secure the terminal protectors, don’t sandwich the plastic to attach the cable lugs. Provided cables are 50mm2 (equivalent to #1AWG) vinyl jacket makes it look bigger. This should be sufficient for most but it should be noted that it will get hot at sustained full rated load and will account for 1/4 volt loss at the inverter’s terminals when loaded and when the battery is low it could cause a low voltage shut down that little bit earlier. Since the inverter is so good for the price point I won’t take a star away. For a good install and any length of distance longer than cables provided, use 4/0 cables and 400 T class slow blow fuse and BlueSea holder. For LifePO4 batteries you will need; one battery with a high quality BMS rated at least 300 amps OR two batteries, each with 200 amp bms’s in PARALLEL to attain full power potential of this inverter. For lead acid perhaps one large battery (high cranking current) may work but it will be depleted much faster than lithium. Be sure to “pre-charge” before connecting even if it’s turned off. A simple filiment light bulb will work.

Very happy with this inverter

So far this inverter has proven even better than I had hoped. I have it cabled to a single 12v Power Queen battery to begin cycling it for future use, but the inverter itself performs extremely well. Everything works. The remote, the readouts, the low-voltage alarm, etc. The cables supplied with the unit are plenty hefty and are more than adequate. I'll be adding additional batteries and eventually have this inverted tethered to a solar panel controller and panels.

So far, works perfectly

Very easy install, plug and play. I’m using it on a single 120A/hr battery right now, the inverter recognized it upon switching it on. Very nice. Definitely use a switch between battery and inverter so that you can turn it on smoothly. If you try to simply attach it to a charged battery it will work, but there’ll be some sparks…

Runs a 15amp angle grinder no problem. Haven’t tested larger draw items yet.

Impressive

Incredible inverter for the money. Was packaged well and nicely protected. They put a little extra into this one. I like the design for the 12v terminals. Very good coverage to protect against accidental contact. The display and controls work well and are informative. This thing powered my Oregon electric saw without fault. It pulls 1800watts when first spinning up the chain then settles down to around 600 watts until put under a load. I was shocked that this little guy handled that task so well. I will be using this unit in a mobile power station tied to a 280AH 12v lifepo4 battery to use around the farm in areas we don't have power instead of lugging around a generator. Only negative I can justifiably gripe about is the included battery cable. The included 3awg cable is only rated for 75-85amps. If you are maxing out the unit at 1500watts you will be pulling 125amps. I was pulling 150amps momentarily with my chainsaw. When I end up permanently mounting the unit it's terminals will be very close to the battery terminals so I will likely end up cutting each 3' cable into 2 x 1' cables and doubling them up, 2 cables on each terminal to help with current load and help reduce any miniscule voltage drop. In the end though I feel it seems pretty petty to complain about the cable, it's cheap enough the cut and crimp your own if your planning on really pushing this unit like I am. The inverter its self delivers as advertised so far.

Legit pure sine, performs as expected

This is one of those items that might be worth seeing for believing. The sine wave is one of the cleanest I've tested in a low cost inverter. Also, the LCD screen is one of the nicest. The cables are stamped with the equivalent of 4 AWG (25mm²) and seem about right. They're nicely made, good ring terminals and heat shrink, and are about as long as would be needed for most applications. I build my own portable solar power stations, so testing inverters is pretty routine for me. While there are a couple of nit-picky things with this inverter that I think could be improved, they're what I consider to be minor and don't offset how nice this unit is. First, plastic... I'm not a huge fan of plastic on the casing. The case is mostly aluminum with capped ends in plastic. I can live with it and I knew how it is constructed prior to ordering it. Next is that having raised mounting flanges would be helpful for airflow between the unit and whatever surface it gets mounted to. Last thing is the fan is a bit louder than some. Why these things really aren't bothersome for me is that I make my own mounts and the unit will sit safely inside a case that has plenty of fans for air movement and the sound will be less noticeable.

Last thing worth mentioning is that while this inverter is remote-capable, it should be more clearly noted in the ad that the remote isn't actually included. In the manual it does state that it's (optional). Bluetooth would be nice, but honestly, for the $109.99 that it was when I ordered it, it's a pretty smoking deal for what turns out to be a nice pure sine inverter.
