Thank you. I can't wait for part 2 so that I can finally complete my solar circuits. I have been searching for a simple explanation on how to connect a grounding cable to an off grid 48 volt system with an all in one inverter.
Long story but same book here. 2 - 5k growatt inverter, 5K transformer. I'm doing All but solar panels right now. I don't know much, But what is your main question right now remix ?
This is the best and clearest explanation with the simple and effective graphic demo for the concepts o grounding and bonding I have ever seen. Subcribed.
Why doesn’t this video have 100's of thousands of views? Why has the RUclips algorithm been hiding this channel for so long? They need to appoint a special counsel to investigate, promptly!
Double check with local electricians on how your grid is wired. My videos are based on North America wiring, and your bonding and grounding may be different in India.
Excellent explanation, but 'bus bar' is spelled with one 's' not two. The misspelling apparently comes from the manufacturer 'Bussman' (who made bussbars, fuses, etc). So this video has amplified the error.
Great series but have to rewatch it few times... What happens if I have an unbonded stand alone inverter (earth has its own connector on the back of the metal case and neutral is not bonded to it), and somehow there is a short of live and earth. And I touch the case? Since it's not able to complete the circuit, I should not get hit?
Great explanation! But I have a question which I'm really struggling to find an answer for. What happens in case you lose the incoming service neutral due to an accident or whatever, but your incoming service live wire is still intact? Since your neutral busbar is bonded to the grounding busbar at the main panel, won't that mean that everything connected to a grounding wire - all of your appliances' chassis - would be energized? Even an RCD wouldn't trip in case someone touches the live chassis because you have the same amount of current flowing through the live, through the load, through the neutral, through the grounding wire, and through the person to the ground. Is there a way to mitigate that or at least get warned if something like this ever happens? Of course, this is in case you don't have a grounding rod bonded to your grounding busbar. But even if you had, will its resistance be low enough to act as an emergency neutral?
Again, I'm not an electrician or an engineer,ibut in my opinion... If the neutral from the grid was disconnected, there is no longer a return path on 120v circuits. Your appliances' chassis would not be live, unless they had an internal ground fault, just like under normal circumstances. The neutral buss-bar is bonded to the ground in your panel, and could possibly provide a return through the ground rod to the ground of the utility pole. My understanding is this would be minimal, due to resistance of the ground, depending on the distance involved.
That depends on the manufacturer of the solar charger or inverter. Some want to see one of the DC legs from panels grounded, but many do NOT want the DC grounded. In all cases, you can ground the frames of the panels, if possible to the same ground the inverter is on.

@@Eliaslionloky I'm in the US, so this may not apply in other countries. You should be able to run a ground cable from your main panel if: Main panel has a grounding (earth) rod connected to its ground bus. You should have only one ground-neutral BOND in your whole electrical system. Your inverter is made to work with grid power.
Sorry, I'm not familiar with them, as they aren't used in the US. We use GFCI (ground fault circuit interrupters) which trip when the current on L1 is different than N, basically detecting that current is going somewhere that it should not.

it is one of the best explanation with professional examples on electrical configuration

Your knowledge and explanations are greatly appreciated.
Thanks!
If our neutral is bonded on grid trasmformer.side, in this. Case we can bound neutral in over main panel side or not?@@ReelClearMediaLLC
I was blind but now I see! Great example and presentation, I understand now. Watching the entire playlist.
I am in Australia but i learned so much from this video. I have never come across this subject so well explained. Amazing and Thanks.

1000%
Great video. Patiently awaiting part 2.
This will help everybody understand and clear up the questions.. very good. Video,
Great explainaering,
Great video, great teacher!
Thanks!
Excellent video, very clear and easy to follow. Thumbs up 👍
Excellent review of fundamentals.
Brilliant. A great explanation
Very informative video. In INDIA most of electric engineer don’t know about ground bounding is used in Hybrid inverter.

Thanks again for a very visually understandable VIDEO

That exact thing happened to us. The neutral wire was disconnected at the light pole. We still had power but it was extremely weak.
I hope you don’t mind to answer my question. What’s the proper way to grounding a solar arrays on metal ground post? Thanks

Excellent...

Is the main breaker panel on the grid?
@@ReelClearMediaLLC no, es un breaker panel independiente

very good explain bro can you please make live video to show in live test anyhow very good way to make us easier to know love from pakistan.
Can you pls explain to your audience why to implement an RCD?

GFCI is the American name for a Residual Current Device. Same thing.
