Can't believe you didn't open it and let us see inside.. I'm betting the PCB is single-sided and only one-third of the the enclosure.. you should make a part 2 where you open it and and try and fix the problem with some smoothing capacitors or something.

Great Idea. Just uploaded part 2 and it will be out tomorrow!

Hi friend, these inverters have several variations: 1000w, 1600w, 220w and finally, 3000w, in 110v or 220v 60 / 50hz versions. Their box is always like this, red aluminum. It has brands: Jinsi, Changi, Powland, Rddspon, etc. It suggests that there is a Chinese company that builds this equipment en masse and resells it to sellers, who simply place this cheap sticker with the brand's name on the product's lid. There is peak power and nominal power. I could be wrong, but I believe they all lie about their rated power. I bought a red RDDSpon 3000w, which said it could handle 1500 continuous watts..... Frustration, it only could handle 944w, after that, it went into protection. They do a lot of false advertising for these devices.

I always buy inverter boards. For example those from sunyima. They are quite cheap and labeled correctly.

Sim, dizem que as placas de inversores Sunyima não mentem a potência declarada.

These inverters are totally fine, as soon as you put a load on them the sine wave is perfect. At least on mine, if you only pull a few Watts, you need to use a small Inverter i have a 5k Peak Inverter, if i pull about 300 Watts out of it, the sine wave gets clean and stable

When you look at the specs of the cheap inverters, many will give output voltage as 110V +/- 10% which is between 99 and 121 volts. This is terrible! It should be 115 +/- 4% for range of 110 to 120V. Some will list efficiency at >80% which is more like a modified sine wave. Pure sine wave should be >90% efficiency. It would be interesting to see the output voltage on the oscilloscope. Thanks for the video!

I buy a 1000W peak and the sinewave is actually very good even under load, Controled with my oscilloscope

How long has your been working?

I also bought the same one for only 30 euros (500w, 1000w peak). I also have one with a modified sinus (4000w peak) which also works well, no flickering with the led bulbs (and I'm testing one big led of 25w and 4 leds of 15w in the same time). Both, pure sine and modified sine wave inverters works fine (if there's no heavy load). I also have a 3kw petrol generator. It produces clean sine, and when under heavy load the led bulbs flickers, otherwise it works fine.

i use epever inverter and solar charge controllers. It is Chinese products but it is good products for the money. And they always deliver what they are rated for and more. My inverter is ip1500 12v. Fineprint says it can deliver 1500w for 15 minutes but it depends on how hot it gets. Had it deliver 1700 watts for a few minutes no problem. Its fused for 200amps.

@mr.makeit4037 2 жыл бұрын

I wish more people would use 36v, 48v inverters. Way better than 12v. Cheaper to wire and more efficient.

@stevenc22 2 жыл бұрын

Agreed. I am not a fan of 12v. You need super thick wires for 12v.

@Madsci-zy8wm 10 ай бұрын

The problem with this cheap pure sinewave inverter is that its a high frequency, transformerless inverter. If you want an inverter that will last then you need to purchase a low frequency, transformer based inverter.

Mine is labelled as a 2000W "Power Invereater" - yes, they actually spelled it that way, and it can't even power a 700W vacuum

@dantronics1682 Жыл бұрын

The cheap inverter is only 500w, It state it pure sinewave but it may be modified, I have a 24v one and even though it advertise as 1600w its only 600w (fuses never lie) If you open that one (remove the top screws, 2 on each side the lid opens) see what fuse is inside but just ignore the flimsy wire from the motherboard to the socket.

I bought the same model but 1000W (peak). Very cheap but it can only handle 200-300W. Surge power is not near 1000W. The only use I see is charging devices and running some led luminaires.

@mr.makeit4037 2 жыл бұрын

If you still have this, try using it to charge cordless batteries. Hopefully you have a few chargers. I do this with solar. And cheap inverters. So far so good 👍

Thanks for the video, I want to know if this will work for me. I have a submersible pump. , single-phase ** **Pump Specifications:** ** - Power: 500W 0.67HP - Current: 3.8A Steady running current - Voltage: 220V - Frequency: 50 Hz - Max Flow: 35 L/min - Speed: 2860 rpm/min - Peak running current - I don't know how much exactly I think it will be 11A The operating time of the pump is 15 minutes per day. 1500/3000W inverter is good ? or inverter 1100/2200w

@stevenc22 Жыл бұрын

220v x 11a peak is 2500w. The problem is a 1500/3000 inverter can only do 3000 for a second or two. The big motor in your pump probably takes 5-10 seconds to spin up drawing the 11a for longer than the inverter can supply. I would just buy a good quality 2500/5000w inverter.

Why didn't you show it inside? to see the components that the fake inverter has, it is possibly incorrectly sized and designed, like every generic Chinese inverter.

I've powered 12 inch color CRT's of a 75W inverter. Even a vintage desk fan. Non sin wave either, so the fan was slightly impressive. Capacitive stuff though? Fssst.... Yeah, I can't imagine that going over the best. Mathematics is a bitch.

It is worth knowing cheap ones suck but they’re cheap expensive ones are really expensive so for the low-cost it’s not gonna be great but the low-cost is probably good for people you definitely overpaid for this one. They are not worth very much money. If you find it for around 20. It’s definitely very good for the price.

All high frequency inverters from China suck. Even the 6kW and 12kW high frequency inverters from China suck.

@markp2865 8 ай бұрын

How do you know if an inverter is high frequency or low frequency. Does it say in the spec sheet? I have never seen any spec sheet say this. Maybe you can go by Peak power being greater than 3x the continuous power.

@quickquote1568 8 ай бұрын

@@markp2865 High frequency inverters are manufactured on the cheap, so they lack a heavy duty, iron core, copper wound isolation transformer, so they're far lighter in weight. A 6kW high frequency inverter charger, even with MPPT for example will typically weigh less than 60 Lbs.
