Pure Sine Wave Power Inverter Review. 

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

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

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

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

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

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.

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

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!

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.

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

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?

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

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.

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

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

You went full send for the load test lol.

what is the no load current draw at idle please?

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.

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

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

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?

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

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.

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?

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.

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

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

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?

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

What type of battery is it hooked up to?

Can this inverter be used with a lithium battery?

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.

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

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.

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

300 dollars, to high, you can get one that size for 140 dollars

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.
