Really appreciate that you hook it up to an oscilloscope and show the sine wave.

[@my2centsrc202]

Thank you very much for this video. You're the only one that actually did a good job at letting us know exactly how it performs and not just a on boxing. I'm definitely going to subscribe and because your video made me know about it and buy it

[@ScottGearChannel]

Thank you very much for the compliment. I hope it works out for you.

[@Area61Command]

Excellent video, really good. Thank you!

[@maxenra]

Picked this model up today and installed in my semi-truck. So far I've only tested it on my 700w microwave, and it worked flawlessly. Haven't decided whether or not to mount the remote switch or not though.

[@ScottGearChannel]

Be Careful, thanks for watching

[@maxenra]

@@ScottGearChannel Thank you sir. Been working great so far. Absolutely love it!

[@charlescoker7752]

From the CarCare Nut channel. He says a alternator is not designed to charge a very low battery. You must put it on a battery charger. It will shorten the life of your alternator. If you just run your vehicle to recharge it.

[@ScottGearChannel]

Great point. Thanks

[@rgarizonahomestead2729]

one issue i have with it is you cannot hard wire the unit to a standard 110 outlet but that's a side issue thanks for sharing the review. please have a great weekend

[@my2centsrc202]

And the product is for a situation that you need AC power, so why would you hook up the unit to AC power if you already have AC power?

[@hksjoshua]

Means you cannot run dedicated power line from this unit to install in a rv to power it.

[@rickturner2757]

Would have liked to see how its was connected to battery and wire used

[@ibdaffy]

Hello Scott! I just ordered one yesterday. I came upon this review and I do feel validated in buying this! I enjoyed your review, straight forward and gave me the information that was important to me. You are knowledgeable, easy to understand and personable. Of course, liked and subscribed and will check out the rest of your videos. Thank you for sharing, it is most appreciated!

[@ScottGearChannel]

Thanks very much for watching and thanks for your compliment. I hope it works out for you.

[@mr.toliver2717]

I just bought one thank you great review 👏👏👏👏

[@skunked42]

You went full send for the load test lol.

[@boober2012]

Thanks going tomorrow to trade my 5000/10000 watt one in for the 3000/6000 pure wave

[@nowayout73]

Great review sir. Definitely what I was looking for thank you.

[@ScottGearChannel]

Thanks

[@danlah1303]

Mine had bad GFCI out of the box. Would run led string lights but Tripped under moderate load. Red light “low life” flashing on the outlet. Took it back next day.

[@emeraldacrefarm9976]

Thanks for the video! You answered questions I wanted answered. I liked the video.

These cheap high frequency, transformerless inverters have a short life expectancy. Especially when powering inductive loads like full sized refrigerators, large power tools, portable AC units or large microwave ovens. The reason for this is that all of these lightweight, high frequency inverters lack a very critical component. That critical component is an iron core, copper wound output transformer. Without an output transformer to act as a buffer to absorb the electrical surges provided by the “Flywheel Effect” inherent in the physical amount of a transformer’s iron, these surges and damaging reverse voltage spikes must be handled directly by the inverter’s MOSFET transistors, essentially shortening their life. You might be able to start and run some high surge loads when these high frequency inverters are new, but every time you fire up one of those inductive loads, you're shortening the life of the MOSFETs in these inverters. To make things even worse, lightweight, high frequency inverters run much hotter and their internal components are far more stressed due to their high switching speeds and use of high voltage components, These two factors makes the low cost, off spec, Chinese made components such as capacitors, MOSFETs, diodes, resistors and ICs that are used in these inverters, far more prone to early failure. Simply put, high frequency inverters are better suited for like duty, electronic devices, and low frequency inverter are better suited for heavy duty, high peak power appliances. Another major consideration with many of these lightweight, high frequency, transformerless inverters is safety. First of all, high frequency inverter don’t have Isolation between the Neutral and Line which increases the risk of a shock hazard. And second, during a catastrophic of the failure of the inverter’s circuitry, all it would take is for the AC output monitoring circuitry to fail and one of the MOSFETs in the inverter's H-Bridge circuit to short to ground, and these high frequency inverters can send dangerous, high voltage, high amperage DC current straight to your connected AC loads which will not only damage most AC appliances but can also set those AC appliances on fire.

[@user-wr3gp8hj3i]

Just picked one up open box for $150 I have 5 days to test it, would jumper cables be ok just to test/put a load on it? Edit: I don’t want to buy 2ga cables yet until I know it works (only bought inverter because it was a deal, don’t want to invest unnecessarily)

[@bluegizmo1983]

Does this inverter have an Auto Shut Off feature so that it turns itself off automatically if there is no load for X amount of time, so that it doesn't drain your vehicle battery when sitting for awhile?

[@jonnyvegasxd4058]

This is one that I'm looking at definitely want to go with pure sine but I've not seen anybody do a review on a full size refrigerator being plugged in. Any experience in this area? Thanks for your time and video.

[@davemontano3790]

I’ve heard you may need a 3000 to be safe if you go that route! Idk much about them just what I’ve heard

[@zachmiller9175]

​@@davemontano3790if you can plug it into a standard outlet it uses less than 2000w, you can't get more than about 1800w out of a 120v 15a outlet. 4000 peak is more than enough for a refrigerator, they have a spike in draw when the compressor starts then pull a few hundred, maybe 1000 watts tops while running.

[@CR8VE]

I have the 3000 W. And put under load from jump Street it wants to crap out. It's a true sine wave I don't know why he thought that was the first one. Personally I think they're all crap If I have known at the time I would have bought something way better I thought because of its size and what I thought I'd be able to handle something but they are not as good as id hoped

[@chachotapia]

Yes I hope you do bring us more reviews but I would like to see how it does with a craftsman 3 gallon 1 hp compressor with these inverter or th 1500 thank you in advance

[@jinhur8193]

What size wire should i use to ground the chassis with this model?

[@OcRefrig]

Wondering if it still works ? Good video. wondering about the fans too. temperature controlled ?

[@ScottGearChannel]

It has been a few months since I used it,

[@DaveDrawing]

Nice video! I am looking at buying this exact inverter and your video was very helpful. I need to buy it very soon, and want to support your page if I can. Are you a Harbor Freight Affiliate?

[@ScottGearChannel]

Thank you for asking but currently I am are not a Horbor Freight Affiliate. Hope it works out good for you.

[@thebeerphilosopher]

Could I just run this in my small shop (no utility power) to power an LED light and one power tool if I hook up a car battery? If the battery isn’t in a car, how long will it work? Will it recharge w/o a car to run?

[@Sartre_Existentialist]

Question. I bought a 500w inverter. When I first plug it in to a cigarette lighter socket without a load, it reads input at 12.3v and output at 120v on the inverter LED screen. However, I plug a laptop into one of the standard outlet sockets and the input voltage drops about 2 volts to 10.2 and the inverter starts screaming. I plugged this into my other trucks cigarette lighter and got an input read of 14.1 volts and when I plug the laptop into it, it drops to 12.2v and there are no alarms. Is the issue that the inverter I bought is too small for the load or is the first vehicle just not able to keep up with the demand? The laptop charger says it's 248w.

[@Notinpotatoquality]

Could my 10 awg cable be what's causing me the status message of hi temperature?

[@dmcd7333]

Yes, a 2000w inverter needs 2 awg on the back terminals for battery hookup. If you are using 10awg on the AC output side and the cord is 50ft, yes, that would cause a voltage drop due to resistance of the length of cable. Hope this helps.

[@davidjohnson7852]

Hi, I don't know anything about electricity really except for I will not touch any open wires. And I probably get electrocuted screwing in the light bulb. But I am buying pallets that includes ceiling fans and ceiling light fixtures and I need to test to make sure they work before I sell them. And I was wondering what equipment do I need in order to connect them up and test them in my storage unit? These do not have the type of plugs that you can plug into a wall outlet. It's just stripped wire

[@nolagirlhomestead]

Question: should I buy now or will price drop closer to end of year? Currently $75 off (likely 2023 models)

[@GoatZilla]

Overvoltage is spec'd at 15-16.5v. Would have been nice to test that. Low voltage cutoff spec'd at 9.5-10.5v. Would have been nice to test that. I'd imagine the only reason to buy this big a unit is to try to run a power tool which is largely inductive. Would have been nice to test that. Apparently there are 8 40a fuses in there. Are the fuses hard to get to?

[@my2centsrc202]

He did a better job of other videos on here about the same inverter, but if you don't like it make your own video, it will be very interesting

[@GoatZilla]

@@my2centsrc202 Eh I would say it was mostly average. The most he did was look at the waveforms, but really a THD meter would have given us the same or better info. There are a couple other reviews that are less advertise-ish but test more important scenarios, like inductive loads.

[@PaulG.369]

Would have been nice to test that

[@WCxColosus]

I was looking at this to run a small 9amp shop vac and some other lil things. Would this work with only one 12v battery? I would prob have to run it with the veichle on so i dont drain the battery.

[@tallcool1ify]

Can this inverter be used with a lithium battery?

[@davestennes305]

Just hooked up to a 100ah lithium, works fine.

[@dmcd7333]

Inverters can be use with SLD, gel, AGM, or lithium. Just be aware of battery voltages and your depth of discharge for each type of battery.

[@tristanstanford9784]

Would this pure sine power a Input: 100-240V 50-60Hz. Output Voltage: 20V. Output Current: 15A. Power: 300W computer charger? Any help appreciated.

[@johnhughes3963]

What type of battery is it hooked up to?

[@ScottGearChannel]

I believe all i had available that day was a standard 950 CCA auto battery. Thanks

[@petercullati39]

what is the no load current draw at idle please?

[@stphinkle]

I wonder if the little inconsistencies in the sine wave on the inverter is the result of it being a stepped wave or perhaps it uses a digital chip to create it.

[@ScottGearChannel]

could be. thanks

[@anio6865]

Do i have to keep it plugged into an outlet to use it ? Or is it portable ?

[@ScottGearChannel]

it is not very portable, you would have to be attached to a battery

[@mba2ceo]

WTF ? Show the wave after plugging in a FRIG & labtop

[@playboy4life18]

Exactly, they keep showing us these small items, this video is worthless

man for what you pay, the renogy ones create a much cleaner signal. Thanks for showing that. Hard pass at that price point. Proof again, harbor freight only sells garbage products NOBODY should buy.
