Im a beginner. This was EXCELLENT video explanation for me; thank you!!!
Most helpful video i've seen so far on series/ parallel comparisons . Helped me to get the theory down pat. Thanks tremendously.
Finally, a video I could understand. Thank you.
Thanks man you answer my question. Very very good instructor Have a good day.
Thank you! So many confusing videos out making things complicated when they really are not. Great job!
Very helpful and clear information. Thank you!
GREAT explaination using real panels and solar generator and explain and actually connect them and show them and how they connect EXCELLENT!
Thank you for explaining this all so well!!!
Tytyty I’m installing mine by myself an had a lot of questions! I feel confident now!
Great Video. Looking forward to trying both setups.
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.
Simple and easy to understand. Thanks.
Excellent presentation- thank you. 👍
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 TH-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.
You explain it really wells, great video thanks
Wow thank you thank you thank you, at last , the best video on TH-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 TH-cam, great big thumbs up, from Wales United Kingdom,
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
Great explanations, just what i wanted.
I learned the word finagle. 😅
Thanks for the video anyway. Good stuff.
Awesome just a beginner and like the rest brilliant tutorials
great explination! thank you so much!
NIce video, the best I saw so far
Thank you very helpful 👍
Glad to help!
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??
Parallel adds amps series adds volts
Well done. Thank you
Thnaks for the info.
Thank You 🙏 it is kind of hard to find reliable sources.. 🙌
Awesome videos thanks
great one handed manipulations
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?
Thanks for this video
Thank you!!
Very educative
Thank you nice job
Appreciate it!
Thank you very informative.ill make sure to catch your videos.like I day thank you.👍
Best video this helped along thank you
Thank you!
Pretty cool video thank you
Genius ❤❤❤❤❤
Good info.
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 ?
Thanks good explanation
Appreciate it!
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?
For parallel connection the mc4 must have a built in blocking diode
Thank you..........
You're welcome!
Very good 😊
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'?
Great video
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
You're welcome!
Great video very so people can understand
Nice info. thx. i just buy Longi 555Wp but the cables in the backside not show, Wich one is + and -. :/ so male Always +?
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?
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
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?
Good work
Thanks a lot!
Can both the 4 in series and paralell both charge a 12V battery? Or is a 24V battery bank needed?
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?
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
Do I need fuses if i'm doing 4 100W panels in 2S2P?
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.
Stripped wires 😅
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
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
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
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?
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
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?
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.
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?
Soooooo helpful. My gosh. Thank you for explaining it like your viewers are first graders haha.
Steven Wright gives a tutorial. 😄
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
Hi. I have a 40 volt Ac/Dc solar pump my panels are 25 x 2. Can I make 40 volts in series?
Hi,
I have 5kw inverter with max 145VOC and 4500w, 9 panels 40voc and 11amp each, and
a 2 in-1 out combiner box (fuses are rated 1000vdc and 30amps).
I can have 3 strings of 3 panels each totalling 120VOC and (11.6amps) , and use 2 MC4-Y connector on 1 input of the combiner box?
Will I still see 120VOC and 11amps with the 9panels (3panels in series to parallel)?
Thanks in advance
I suggest getting a combiner box that can take the amount of strings you have. You will mess a lot up but connecting some in parallel before the combiner box.
@@offgridstores Thx for reply
How do I connect my 04 no 170w solar panel of voc 23v each to my solar Invertor of voc 35-55v.
Sir good
Thanks
I have 3 x 400 watts panels which l want to make an array of 1200 watts connected in series, is that possible?
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.
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
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.
Which one is the best connection series or parallel
How much is too large for your controller. Can I use a 20 or 30 amp controller for possible future expansion if I really only need a 10amp controller starting out?
it is always better to give space if your system is 10amps
then use 20 amps charger co troler
Series or parallel? ....which way is better for the quickest charge as either way is within the parameters of my Delta 2?
I have 2 panels one being 100 watt and the other being 120 watt?
Series is better in my opinion because it takes less components
@@offgridstores Perfect.... Appreciate the info
Sir, delta max is the same ad charging controller?
hope so
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 th-cam.com/video/J9jqUwOdnEI/w-d-xo.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
Is it okay to wire a 17.6 v solar panel with a 18.3 v solar panel in parallel? The voltage is abit different
As long as the amps are similar it shouldn’t matter much
*Whar is better more ampere or voltage ?*
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
Hi, how much 375w panels (38v and 11amps) can I connect to a 5kw hybrid inverter with 145VOC
We would need to know the max input amperage of the inverter as well to give you a correct answer

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
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.
If the Delta Max can take 800 watts,do you put 2 sets of 4 ( 100 watt) panels in series then add those 2 sets together in parallel?
Also what do you recommend for use in attaching these to a shed roof?
Watt is not voltage watt= Amps * Volts so the 100 volts allowed in is different than 800 watts.
@@TheNoobstalker
The ECOFLOW 100 watt panels are
18 (17+) volts and 6 (5.9) amps each
The Delta Max maximum input is 800 watt ,100 volts and 13 amps
So I was correct about 2 sets of 4 panels in series then connecting them parallel.
However, I also have another smaller generator whose maximum input is
500 watts,60 volts and 15 amps.
I am wondering if it would be a problem to combine (parallel) a set of (2)100 watt solar panels( 36 volts/6amps)that are in series to a set of (4) 100 watt solar panels in series ( 72 volts /6 amps)
Let see if you can help me in my project

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
What about if I have five panels how do I wire it
i just wanted to know how to hook up my renogy 400w kit. don't know what a delta is but don't have one. no answer can i find.
that is another word of charger controler i suppose
So it seems whether to wire panels in series or parallel, one should first know whether the units can be wired in series or should be wired in parallel.
In series and pararel connection,Do voltage and only current increases?
Do voltage and current increases and which one remains constant?
Each Series String you add the voltage and then you would add together the amps on the parallel strings
How would you add 6 panels
I am having some buyers remorse on my eco pro. It's limitations on input voltage, amps and wattage is not allowing me to hook up my 8 -180 watt bourgerv solar panels.
You always need to check if your panels will work with your system. Best way is to get the system first and then tailor the panels you buy to it
It eco only takes in 600 or 700 watts !
Omg thank you. I have a allpowers but the instructions are so tiny I can't read it lol.
Why is it that Google says the Delta Pro can handle 11 -150 volts input and 15 Amps max current but at 0:25 you say it can only handle 100 volts and 13 amps?
Because he's talking about Delta max not Delta Pro I'm thinking.
