Undestand what's inside a solar inverter, how it works and its critical elements that may severely affect your whole photovoltaic and electrical installation of your home.
IMPORTANT: This video is for informative purpose only and it is NOT MEANT for do-it-yourself, unless you are a qualified operator. In no case I shall be held liable for the content provided in this video, and any action you take in relation to such content is discouraged and at your own risk.
This is a two-parts video, previous one is about photovoltaic systems, link below.
Two years ago I installed a solar system on my house, and because of shortage of available technicians (and even materials!) I had to do everything myself, including some hardware components. It was an istructive experience from which I learnt some things that I did not expect to find. So in this two-parts presentation I share with you what I learnt, hopefully providing useful for you.
In this video you will get into the typical inverter, skipping the details and focusing on the conceptual blocks and how they may affect the whole photovoltaic system.
Why RCDs trips, why you may find unexpected voltages on the frames of your panels, and more.
The presentation does not address some topics such as overloads, reactive loads, and surge load such as those caused by induction motor start up. Maybe I will add another video for those topics if enogh request comes from you all.
First part, "Photovoltaic Systems and MPP (Maximum Power Point) ": youtu.be/TwyHmL_N5rs

![How to spot a fault in a circuit, like a pro : hands on electronics [1]](https://i.ytimg.com/vi/ye9dguKy_Cs/mqdefault.jpg "How to spot a fault in a circuit, like a pro : hands on electronics [1]
In this video I show the method to find out a fault on an electronic circuit board. In the specific case we have an ESC (Electronic Speed Control) that is used to control a washing machine motor (used to drive the spindle of a lathe) and somewhere in the circuit there is a faulty contact. It turns out it was a bad soldering that caused an uncertain contact, making the motor to start and stop randomly. The video shows the procedure to spot the exact point where the fault is present.
Wonder how to #faultfinding without schematic? Watch this video too: https://youtu.be/yjxuMwLN7zI

![The mindblowing #photoacoustic effect: #light makes materials to play #sound! - [Redone video]](https://i.ytimg.com/vi/zIQXlf1qLsM/mqdefault.jpg "The mindblowing #photoacoustic effect: #light makes materials to play #sound! - [Redone video]
A piece of fleece generates sound just projecting a modulated light! No electronics involved! (Aside the light modulator.)
*This plays sound JUST with light!*
I reproduced an experiment that led to the definition of the photoacoustic effect. This effect has been first discovered by Alexander Graham Bell, the inventor of the telephone and of the photophone. While this effect is widely exploited in photoacoustic spectroscopy, it is often overlooked by many.
So with this video I bring it to light ...so to say :-)
After a first failure in reproducing the experiment, after some research I managed to achieve results.
Encouraged, I developed a special #LED driver. The final result is amazing: a simple piece of fleece emits #music just for the radiated modulated light!
The effect is regarded to be caused by light induced thermal expansion and contraction of materials.
In doing this experiment I also stumbled upon a weird response from a piezoelectric sensor, with an unexpected and interesting effect that I showcased in a bonus extra section of the video.
Remark: This video has been redone because of missing content and technical issues in the originally posted video.
