Hi! Have you ever heard of the Shoals Plug and Play cables / system? Can anyone judge whether it makes sense to use it? Although they seem to be a bit more expensive, they are extremely easy to use and no professional installer is required. Installation is also said to be very quick and more energy efficient than conventional cables... Some thoughts on it?
Is there a type of "combiner box" available that can primarily utilize power from solar panels (when sunlight is available) and supplement its output with grid power (as a secondary source) only when the solar current is insufficient to meet the required output?
Hello superb video! with 4 strings like your drawing the voltages add up is that right? I have 5 PV strings in series but different voltages and different currents, I can't do a // connection? I have 5 different MPTTs not strings do I need 5 surge protectors 5 DC circuit breakers and a large 63A circuit breaker? thank you laurent
Kya Nitrox 6 kw k liye agar do string lagayen to Kya Dono barabar panels k hony chahiye ? Matlab agar aik string 9 panels. Aur dosra 3 panels. ho to Kya Hoga?
What I learned today is that, 1 fuse is 15A and 6 panels parallel-connected to 1 strings is equivalent to 8A x 6 = 48A. Which will overload the fuse and blow if we connect it like your diagram shows.
Can you explain to me why you connect all the (-) and (+) ,except the first (+), together and then conect them with a black (-) cable to the combiner box and in the meantime draw a red (+) cable of the first (+). Instead of connecting separately all the (-) of the panels together and connect them with a black (-) cable to the combiner box and all the (+) together and connect them tο the combiner box with a red (+) solar cable?
• All pv strings connected in series The series circuit definition states that a series circuit is a path where the current flows from one component to another through a single path. • In these types of series circuits, the negative terminal of the component is connected with the positive terminal and vice versa.
Using this example, what is the voltage of each panel before series wiring? Also - what gauge wire would then be used on the output feed to the inverter?
If i want to use this diagram some times and change all (pv1,pv2,pv3,pv4) to series to use it and return again to first diagram ,How to do that without adding new solar panels?
This is a series connection looking at the panels... the only thing that makes it parallel is the bus bur.. you should than connect each string to its own fuse and than from the fuse to its own breaker per string... assuming your inverter handles 4 separate strings in
In the series string, solar panels voltage is added, and the current remains the same. In parallel string connection, solar panels voltage remaining the same, and current adding this depends on your system
Won't work, series voltage is too high for charge controllers in off grid apps. Running long strings is best with microinverters or SolarEdge optimizers in intertie apps.
Agree. Assuming each panel is 25 volts VDC (conservatively), that's 150 volts per string x 4, or 600 volts. That's packing a wallop, and well above any controller (Just the first string along would exceed capability for my off-grid controller). For safety reasons, it's not recommended that 100 volts VDC be exceeded. VDC at the level can kill.
I have solar panels that are rated 540w My vmpp is 40.5 v I’m aiming to connect them to an inverter that runs a motor for water pumping I will use 64 panels so they can provide 34kw. So I’m using 4 strings each with 16 panels in series If i add up the volts in one string i will end up with 650dcv is that dangerous? Also what do you suggest?
@@عزوزسعيد-ع3ت According to what you are saying each of your modules puts out 64/34k = 531.3 watts. I think there might be something wrong in your calculations. Microinverters, that is an inverter on each module, run high voltages as the string voltage is the sum of each module. If you're are feeding an inverter or charger controller that runs low voltages you have to make your bank something like 2 modules in series connect in parallel, that is 2 S x 16p, that will give your a total voltage of~81V .according to your VMPP of 40.5 V.

Make use of string inverter
Instead of going to “inverter in” could you also go to the “charge controller”, then from the “charge controller” to “inverter in”?
some have built in charge controllers
Correct
I am greatly impressed with your ability to draw the sketch. Could you kindly share your preferred drawing program?
Thanks for watching the video ,im using Kinemaster

Many mistakes in the video. Minus wire also shoud go through fuse, SPD comes after MCB....
Why only the + cables go to Into the fuses when we have to use the + polarity and - polarity fuses in the junction box?
I believe that the Fuse he is using are not 2 pole fuses so that's why.
Yeah nice and neat.
Thanks!

I think there series strings coming in so only 8-11 amps per string.

can u show different Voltages per string
what wil be addition
In this scene in the video, the current and voltage of each string should be consistent.

@@charliewatts6895 Voltage does not add up across parallel connections, it's the current that increases, isn't it so?
