Most helpful video i've seen so far on series/ parallel comparisons . Helped me to get the theory down pat. Thanks tremendously.
Im a beginner. This was EXCELLENT video explanation for me; thank you!!!
GREAT explaination using real panels and solar generator and explain and actually connect them and show them and how they connect EXCELLENT!
Very helpful and clear information. Thank you!
It would have been nice to have shown four or three panels wired ALL in parallel which would have made this video complete and knocked the subject over the home run fence in center field. Certainly, you did a great job. Thanks. Advantages and disadvantages?
You shouldn't really need that many panels in parallel. Series is better!
what?@@offgridstores
Nice video. I'm going to be plugging in to a Rover 40A MPPT charge controller. It does not have receptacles for the MC4 connectors. How do I plug in to the controller? Do I clip off the MC4s and strip the wires and stick them into the P1 and P2 receptacles?
UPDATE: Nevermind. The charge controller is set up to receive stripped wires.
great explination! thank you so much!
Very helpful, thanks.
Well done. Thank you
Best video this helped along thank you
Thank you!
Out of doing series vs parralel wiring, will the performance and outcome of energy gains be the same ? Or not? I mean... it should be the same. Energy X + Energy X = 2x. But is there a performance or efficiency difference in how it feels or ' which seems to work better'?
Awesome!!!
Thnaks for the info.
Do you know if you can series different brands/types of solar panels?
What if I have 3 Panels 45VOC ,10A ...and Can I connect 2 In Parallel And Remaining 1 in Series... Can That Parallely Added Amps Can Go through the 3rd Series panel? Is it correct?
Can we connect if we had odd number of panels... Like 5 strings of parallel 2 panels (Total 10 panels) and connect that 5 strings in series and last 1 panel also in series to the 5 strings?? Is it correct??
When doing parallel circuits you want to have equal panels in each. So with 3 panels you want to do those 3 in series if you can. If not you can buy a 4th and do two sets of 2 panels in series parallel
So I have the Delta Max plus (4) 200 W panels. I was thinking to wire 2 panels + 2 panels in series and then those pairs in parallel...would this be a good or do you recommend a better way?
Thanks for this video
Thank you for the video. I have just built a carport and because of the roof dimensions I have bought seven panels for the roof. The arrangement will be one row of seven in portrait. I have not really thought about inverter or the wiring yet but from your video it appears that having an odd number of panels will cause me some problems. Do you think that I will have to wire all the panels up in parallel?
In series, you multiply the VOC but in parallel, you instead multiply the amps? So in your parallel example, each pair (in series) is 45.6V at 5.78A. Then merged with the other pair (parallel), your final result is 45.6V at 11.56A? So either way, the wattage turns out to be the same. It's just a matter of staying under the power station's max volts and amps. For instance, a Delta 2 has max solar input of 60v at 15A so four 100w panels in parallel will work (45.6V at 11.56A) but it won't work in series because volts (22.8x4) will be way over the max 60V. Am I understanding correctly? Thanks!
Very good video and explanations for series and/or parallel connections. I'm new to solar and when people just jump into it , it can be costly and most confusing. There's nowhere really to go or to call to get help, so UA-cam is where I go but it takes forever to find the video demo that answers my exact issue(s). This is one of the best videos on the 'tube I've seen so far. Good teacher, too. But one thing, check your audio levels before uploading to youTube. Using the camera mic or the phone mic just doesn't do the best job. Use an external mic or a wireless mic for better quality sound. Nonetheless, good video, bro. I'm a fan.
Wait a second... Wire four in series and you have an output of 91.2 volts and 5.3amps. So if you wired another set of four in series, and then both sets were wired in paralell to the battery, wouldnt you have 91.2 volts and 10.6amps? Or am i missing something. Sounds like that would be within the limits on the delta max, right?
Yes. you could wire up to 4 in a series and another 4 in a series then run each set parallel and it would be 91.2 v and 11.56 amps. That would be the limit of the Delta Max
@@jddragonfly8461wait wouldn't that be double the output of 91.2×2 with 11.56 amps??
In series voltage is additive current remains the same while with parallel its the opposite
How can you wire 8 solar panels in parallel
For parallel connection the mc4 must have a built in blocking diode
Which one is the best connection series or parallel
Good work
Thank you! Cheers!
In series and parallel which is now the best to use?
I have two panels of 430Volt 10amps of 24volt inverter or 12 volt inverter. The panel produce 38volt each given 28volt inside charge controller for one. If I connect in series I will have 76volt, is it not too much for two batteries?
Thanks man you answer my question. Very very good instructor Have a good day.
Finally, a video I could understand. Thank you.
*Whar is better more ampere or voltage ?*
Does the sequence of the + to - matter? Can I connect the 1st panel to the third etc.. and have the 2 output wires come out from the middle panels instead of the 1st one on the left and the last one on the right?
Newbie question. If I have 4x100 panels being used to charge 2 12v batteries which are connected in parallel for a 12v trailer system, does it matter how the panels are configured going into the controller? Or does the controller know what the battery bank requires for voltage?
It doesn’t matter as long as you are in the allowed input voltage of the controller. It’s the controllers job to then step the voltage down to one that is low enough to charge your battery bank
Thank you very helpful 👍
Glad to help!

I have 12 solar panels of 310watts 44v each panel. This is enough to feed this inverter??
And how I connect this panels ? All in parallel or how many panels in serie and then in parallel ?? Please 🙏 really need help thanks
The background music makes this video unwatchable.
I'm no expert, but that 4s was good.
But you could put 6 panels onto that system.
Do a 3s 2p system.
Forget the amps..... Mppts are like light bulbs.....thay blow with too much voltage, but will only take the watts thay require to run (so if you have 18amps...and your mppt can only use 15amp, your mppt will only use 15amp)
It's voltage that is critical to stay under your mppt charger.
Just another note......watch your charging "c" rate for your batteries. Don't go overboard on charging your battery as you'll cook them.
Even I screwed up......I started my system then learnt everything......I'm human and not an expert but I do love electric.....
Thank you for this. I’m electricity illiterate. Which of these two configurations would charge my Delta Max faster?
Depends on your panels.
@@offgridstores I have a 160 portable panel from eco flow. I want to get another one to charge my Delta Max faster. How should I hook up two, 160W panels to charge the generator faster?
You can wire them in series in this case and you will be fine. Also we have them on our website for cheaper than EcoFlow until the end of January. Here's the link: offgridstores.com/products/ecoflow-160w-portable-foldable-generator-solar-panel-efsolar160w
9:44 NOTHING is ever IMPOSSIBLE, always check voltage, current, and polarity BEFORE you plug it into your power station or charge controller!!!
I have 7 panels connected at 575 watts in series - 330 volts to inverter 4.2kw Daxtromn. Not connected to mains or batteries Can I add another one but in parallel? Because I get a maximum of 7.3 amps and the panels label say 13.60max At 2 kilowatt load, the inverter restarts, and I should have 3.5 kilowatts at 35 degrees of sun?
Hey folks .. I believe Im past the beginners stage of solar , though im still wanting to get things right the first time ..
Some comfirmation on my question would be much appreciated ..
9 x 200w ( 40voc) panels - all in series .
360v and say 1800w
Disconnect the 9th panel and parallel it with the 8th panel
320v and 1800w
Im guessing the overall amps would increase only slightly because the 8th and 9th are paralled ..
Could this cause any issues with voltage and amperage inconsistancies ?
Is it worth it ?
Can i continue adding paralled cells to all the other cells to double the amp output ? They will all be fused pairs .
I have a shading issues for the reason for wanting to do this .
Thanks in advance 😊
Hi thank you for your helpful videos.
I have a question about my solar system. I had 12v solar system with 10-180 watts panels and 2 lead acid batteries 12v/200amp connected parallel. I have them about 5 years and last month I bought 2 lithium batteries 230 amp each. When I connected new batteries, my inverter would turn on and off automatically every few minutes when there is less or no load connected to the system. I have 5000 watts Giandel inverter. I thought my inverter had a problem so I bought another inverter. This time I bought a 24v 5000 watt inverter and switched my solar panels to series. And I still have the same problem.
I searched online but could not find any helpful information. Will you please help me out with this issue?
Thank you so much.
I’m trying to do 2s2p with 4 250 watt panels. Open circuit voltage 37.6 each. I know I need some sort of branch connectors and 20 ft extension cable but I can’t figure out the gauge of extension wire I need
So i'm just curious. Can this set up work :
3 panels in series
3 panels in series
2 panels in series
And have them linked in parallel?
Not sure if I ABSOLUTELY need the same amount of panels for each series??
Other exemple :
4 panels in series
2 panels in series
2 panels in series
Then all connected in Parallel ?
Great video - put some affiliation links there so we can support you. For the parallel kit what's the official name (so i can look it up). Thanks
Thank the Lord!!!! You made this video!!! My wife and I where connecting everything we have 10 panels 👀🤣 and we where using y splits
Know how you feel, I'm about to start buying what i need, and nearly paralyzed trying to move on it.
You explain it really wells, great video thanks
How do I connect my 04 no 170w solar panel of voc 23v each to my solar Invertor of voc 35-55v.
I have 10 200w panels and a 100v control panel and a 8000w inverter. How would I hook this up?
Dumb beginner question, is the total KWh of power captured less with either serial or parallel set up?
Can both the 4 in series and paralell both charge a 12V battery? Or is a 24V battery bank needed?
This is much appreciated. I have a bluetti ac200 max that can stand VOC 145 and 15 amps.
If I have 4 solar panels that are 38 vocs each and 8.8 amps each, im better off just doing 3 in series right? Because if I do them in parallel its still over the allowable current for my generator it seems. And if I do all 4 in series its over the voc.
3 in series seems to be the middle ground even though its over the amperage, would that be okay?
You can go over the max Amps but not the max voltage.
Thank you so much for this video! If you or somebody reading this could answer my question... do the negative and positive wires have to be the same length? I'll be fitting 3 on my van and one of the cables will have to travel further to reach the inlet. Would that cause any problems?
how you can make something so simple look so complicated -_-" at least tell something about the reason, like shadow for example
So parallel increases the amps and series increases the volts But it increases the water both too?
Does wires coming from panel need match? 1 is 4mm and other is thin?
I bought 10awg 6 mm
To add feet wire
We suggest using the same sized wire throughout for your panels
I have 3 x 400 watts panels which l want to make an array of 1200 watts connected in series, is that possible?
Excellent presentation- thank you. 👍

Why does it say "12 volt panel" when it's 22.8V?
Bruh I’m high trying to learn this and it’s so confusing lol 😆

Could I run (2) 110 w panels and (1) 220 w together?
Thank You 🙏 it is kind of hard to find reliable sources.. 🙌
Do I need fuses if i'm doing 4 100W panels in 2S2P?
i had 21 solar panels and one solar panel equal 250w and every tree solar panels connecting in series and seven group in parallel and want to connect all 21 solar panels in series with changeover switches and using parallel again after some time in sun day ,how to do that please? because i do not want to buy another panels. 21 solar panels 7 group parallel for two inverter for home and 21 in series for vfd drive for submersible pump 3hp 2.2kw single phase ac.

What about if I have five panels how do I wire it
Great video, very well explained! Newbie question here. I got 2 portable panels, from different brands though and different power ratings as well as voltages. My charger is a very capable MPPT 40 amp, so I'm not worried about its input. Do you suggest to connect the 2 units in parallel or in series ?
Thank you! Great video
Simple and easy to understand. Thanks.
Great Video. Looking forward to trying both setups.
Nice info. thx. i just buy Longi 555Wp but the cables in the backside not show, Wich one is + and -. :/ so male Always +?
Say 3 panels in parallel, and 1 panel is in the shade, would it (and thus all) need a diode for protection? (would the current want to run in the wrong direction?)
All panels now a days have diodes for protection. But no the whole array would just lower down in power.
@@offgridstores Thanks for your reply. So you say that my panels (295W 2 year old) highly probably have a blocking and bypass diodes in them? I can not easily get close to them to open one. How can I test if they block current in the wrong direction... I can get access to its 2 wires. Is this something a mulimeter could do.. (I am not the most experienced).
@@offgridstores Good info about blocking and bypass diodes ua-cam.com/video/J9jqUwOdnEI/v-deo.html
@@offgridstores yes, all panels come with diodes now a days, but these diodes are bypass diodes, they aren't blocking diodes. you still have to put blocking diodes on your own. otherwise the battery will put some current on the panels at night, you're going to have leakage of energy
Newbie here...why are we using the VoC and ISC to calculate instead of VMP and IMP?
VOC ×ISC don't Equal to the total wattage of the panels so is there a reason for using those numbers?
kindly suggest me how to connect 4nos. of 400 watts 24 volt, 50 voc monoperk panels to get optimum voltage (say 100 or more volt and best possible current.
can you do just 2 panels 1s1p? because the amp or voc are to high to run series? I'm new sorry if its a dumb question
How do you do 70 solar panels
Why are all the wires black? It would be better if you had red wires.
I have 30 400watt panels I want to setup without using a bunch of micro inverters or using more than 3 large inverters trying to figure out how to run that without going over my voltage there 48v n 8.33amp
ampers are more important then volts, of course depends on configuration , but i take your video to learn thx
volts are just nothing ahm is imorptant more ampers qicukli load, ;)am/h its how much energie have the batery this why goood batteries have more amp
Hi. I have a 40 volt Ac/Dc solar pump my panels are 25 x 2. Can I make 40 volts in series?
I've got a delta 1300 I've got (2) 200w solar panels in series charging it would it be possible to add 2 more 200w panels and do a series parallel connection?
What will happen if I continue with series connection and put it to my inverter
You will exceed its max input voltage, if you're lucky, it will protect itself and shut. But if it doesn't have over voltage protection, or if the voltage is too high, it will turn into a fire hazard.
That helped me a lot. It's apparently hard to get to 500w with a 60v limit but at least now I'm charging by more then double what I was getting before in parallel
My question is if I have two arrays with four panels in each array in parallel can I just series the two arrays at that point to increase the voltage?
The best way to go about it in my opinion is 2 strings of 4 panels in series. And then put those 2 strings in parallel.
@@offgridstores I will do that I appreciate the info, is there a reason why we don't do it the way I was thinking about doing it, I just like to know as much as I can, I don't mean to question you in a wrong way I'd just like to know if there is a reason why or if it has been tried?
@@flintriverkayaking7051 bear in mind parallel voltage same
series current same.
Right now, I'm running 8 320w panels to my 6kw inverter 4 in series n 4 in parallel.. can add 8 more 450w all in parallel in the same inverter through the combiner box?
How would you add 6 panels
If i have 8 Renogy 100W 12V panels and i have the MPP LV2424 can i connect 2 panels in series then parallel to complete a 24V system. The MPP VOC is 145V
Why not just do all 8 in series? As long as you don't go over 145V Voc you should be fine
@@offgridstores The VOC on the panels is 24.3. 8 x 24.3 = 194.4 exceeding the 145 VOC on the inverter.
Then do two strings of 4 in series
Omg thank you. I have a allpowers but the instructions are so tiny I can't read it lol.
warning all mc4 connectors are not the same some have different threads and water proof seals once you buy mc4 connectors stay with that brand also when connecting extension lines they will be different than what you have so beware and buy extras
Thank you very informative.ill make sure to catch your videos.like I day thank you.👍
Wow thank you thank you thank you, at last , the best video on UA-cam, very well explained, well easy to follow, well presented, video was amazing, nice one, keep it up, again thank you for the best installation video on UA-cam, great big thumbs up, from Wales United Kingdom,
Im locked up on how long of a run this wire is good fore before there is voltage drop? How is wire size calculated for various # of panels?
Thank you for explaining this all so well!!!
I learned the word finagle. 😅
Thanks for the video anyway. Good stuff.
Great explanations, just what i wanted.
