"Pure" sinewave, but hook up an oscilloscope and that is basically a square wave... or a really really bad modified sinewave... But hey, go for it. Without an oscilloscope you'll likely get to see lots of magic smoke

Really, as soon as a design features a 555 you know you'll be getting the most basic result

Get the right components, get the right schematics, solder the shiat together.

No need to over complicate, I'm not trying to compete, all I want is to see if I can make my own system to my own taste.

Assembling the actual thing is not my problem I do this has a hobby mostly, I have a nice PCB board making station going so I can make my own boards etc.

All I don't have is the experienced knowledge to know what components to use and why.

So that is why I am scouting to see of I can find a decent schematic which will include the layout I need to create on the PCB board etc. Then I start soldering.

Hey.

I am such a noob when it comes to this inverter stuff...

I think you need to look up the definition of noob

I have an oscilloscope and I can see my Inverter I bought is not ideal.

It's the samlex 500watt.

I'm sorry

Here is an actual design from people that know what they are talking about. Yes it is technical, go read it and you will understand the challenges of pure sinewave a bit better.

Links posted earlier is simply a square wave with noise added they are not even in that ballpark of a sine wave. Here is a rule of thumb, if a snapshot of the final output is not posted then the design is crap.

Please, please make a video when you switch it for the first time.

Both is modified sine wave .

Website does say pure but I thought it looked remarkably like the typical modified sine wave inverter one sees at autozone


As for building an inverter, I'd rather not risk a stuff up and rather buy a reputable brand.

I see communica is selling 150w smart kits if you want to learn about them hands on I guess

Thanks you that seems like a really good read. I will have a look when I get home.

Please, please make a video when you switch it for the first time.

If I'm going to attempt it then I will post it on youtube, I just need to find the time to actually commit to this and see if it's possible within a reasonable budget.

In the description on the actual website:

Samlex 300W Heavy Duty Modified Sine Wave Inverter

Output Wave Form: Modified Sine Wave

No idea where the pricecheck website gets the idea that it is a pure sinewave.
