So if you have 4 panels in series and the open voltage nears 100v dc should that also be sized with a factor like the amps is, in my case I would need a 10 amp breaker but my voltage would be about 90v open voltage
Welldone Engr., pls i suggest the IEEE/NEC/IEC standard is to multiply the current by 1.25 safety factor, but most times breakers of the rated value isn't easily found in the market.
Thanks the video and the way you explain the concept. Can you please shed some light on the difference between breakers and fuses and why both are required? I am watching from the UK. Thanks.
Sir your teaching has really bring a change in the area of my solar installation,I really want to thank you, again sir how to calculate to get KVA in solar calculation
These are industry wide safety standards used universally world wide derived from manufacturer consortium testing labs. To get their safety approval letters and stamps from these "safety labs" the manufacturers voluntarily make the panels (of many different sizes and wattage) to conform within these safety margins if properly fused and interrupted by correctly rated circuit breakers. This is why ALL solar panels list their maximum output current and voltages even under fault so that if you use the safety margins as listed in this video you will oversize the wire, fuses and circuit breakers correctly for safety.
The panels have a safety factor of 1.56 because solar panels can over produce more than their rated capacity in certain conditions (in hot weather panels produce less than their rated capacity but in very cold weather they can produce much over 100% of their rated capacity). The battery to inverter connection is a much more controlled capacity and only requires a 1.25 safety factor as batteries, unlike solar panels do not over produce current and voltages because the temperature or sunlight changed.
Following from Zambia, your teachings are not in vain, but making a difference.
This Engr is really trying
His teaches are powerful.

Watching from Bamenda Cameroon. I am a beginner and problem is sizing. I am also a slow learner.
Mr Sunday from Anambra State. Well done
Your teaching added more knowledge to me, even am in the system of solar installation, thanks a lot more grateful, more grace
Watching from Botswana..this is great..
So the breakers here are DC breakers right?.
You saved me alot of research time 🤑
Wow... Thanks

Can i use 60a circuit breaker in the system?
Sir if it a single
panel what breaker should we use
Watching from zambia .
@@linossinkala7840 Thanks for watching
You are doing well Sir.... From Lagos State
@@GaniyuBamidele Thanks
What about from the charge controller to the battery, is it needed?? Nice explanation.👍🏽
Yes... You need to install a breaker between the charge controller and battery.
@@Solarwattng do you have a video sizing that one? Ex: If the charge controller is 60a then what breaker size is needed?

Following from sierra leone
I am from Malaysia
From Sierra Leone... What is 1.56 and how
If I use just 1 panel and 1 battery, do I still need a circuit breaker?
How did you make up with these safety factors(1.2, 1.56). Watching from Zambia.

5:27@@user-dw9ou9sg2p ok😢 thanks Sir. And I'm really looking for a book 📚 I can use to study more about solar system.
i also need to know, how to size solar cable
Good
🙏
Should the breaker be any breaker
*what about the connection that is parallel-series connection*
I'm Joseph Samu from Sierra leone 🇸🇱 I really like your teaching please I want to a friend to you, I'm doing this work
Please make a vedio how to size battery and how do i know how many batteries do i need.

Im watching from nigeria .plss how do get the safety factor??
Why is panel 1.5 SF and inverter 1.25
The panels have a safety factor of 1.56 because solar panels can over produce more than their rated capacity in certain conditions (in hot weather panels produce less than their rated capacity but in very cold weather they can produce much over 100% of their rated capacity). The battery to inverter connection is a much more controlled capacity and only requires a 1.25 safety factor as batteries, unlike solar panels do not over produce current and voltages because the temperature or sunlight changed.
