When starting off in solar it is easy to over-simplify the selection of the right panels to match up with your solar generator, charge controller, or string inverter. I will walk you through an example where I will use wiring in series, parallel, and series-parallel to try and get the most solar input power to charge my EcoFlow Delta Pro.

It's kind of bogus. You have to give your phone number which opens you up to installers using auto-dialers to call you. I don't mind my address because I can toss the junk mail. I think you should make it very clear that people will be receiving calls...Maybe for years. I did like your video and I will subscribe to your channel.
One of the companies I priced for Solar panels was $65,000 for my home, It would take me 36 years to pay for that at the cost of what I pay for my light bill now.
This is one of the best explanations I have seen on the differences between series, parallel, and series/parallel solar panel connections. Your drawings and explanation were very clear and easy to understand. I do feel you left out a couple of important pieces of information for people to realize when they are determining how to wire their panels and what to expect from them. The first thing is a realistic expectation of how much power they will get from a given panel. Most panels will output somewhere between 80 and 90 percent of their rated capacity. So, your panels had a theoretical max of 1,440 watts, but when you multiply that by .85, to account for efficiency losses, you get 1,225 watts. That's about the most anyone should expect from those four panels, no matter how they are wired. The other very important consideration when deciding how to wire up your panels is shading. If your panels don't have bypass diodes to address shading issues, then wiring in parallel, or series/parallel, can ensure you get at least part of the output from your solar array, when the array is in partial shade.
Hey Jason, thanks so much for the feedback. Both additional points are very valid. I actually am planning on doing some testing (wired in series) with shading and talking about the bypass diodes which these panels have 3. I also have some power optimizers to compare if they make much difference since the panels already have the bypass diode capability.

@@everydaysolar Thanks for good video, I am attentively waiting for your next video that address these issues. Right now I have 4 panels that each has Voc is 37.1 and Isc is 8.58 Amp with Ecoflow DP. Currently I wire them in serial, 4 more panels waiting to be wired when I see your next video. Thanks again.
@everydaysolar I have an issue understanding and I'm sorry, but earlier the setup wouldn't work because it exceeded the voltage. But now with 4 it work because you're using amps? But shouldn't it still not work since the 4 panels still exceed voltage?
@everydaysolar did you ever do a comparison of these with optimisers on? Someone was asking about this for 2 strings and shading mitigation when charging an ecoflow. But others have reported interference in MPPT readings for the Ecoflow because the optimisers also have MPPT and cause mixed signals and errors.
To make it easy; panels in series the voltage adds up current remains the same. Panels in parallel, the current adds up voltage remains the same. Nice production. Also more sunlight equals to more output. But you have proven which method is efficient under the present condition.
Great video, thank you so much for spelling this all out in a way that makes sense. We’re just starting out with solar and an EcoFlow Delta, so this will definitely help.
Same here... just bought my new set up
Thanks for making this so easy to understand. Really appreciated.
Happy to help!
Thanks! I needed that.
Excellent example. Love the simplicity you apply to this example. Many of us are not 'experienced electricians', so keeping it simple is GREAT. thank you for making this video.
Dude, this video is the one ive been looking for for the past almost 2 years. Thank you so much for breakfast it down as simple as possible.

Excellent and very well explained video. Thank you!

Great video! It really drives home the point that your system needs to be designed with the parameters of each piece of equipment in mind so that you can achieve maximum performance (i.e., efficiency and effectiveness). The PV panels you choose need to be well-matched to hybrid inverter/controller/charger or whatever load you choose. As I have found in my research and readings, there is a lot more to designing a solar system than immediately catches the eye., and this isn't even touching the NEC regulations for grid-tied solar systems. Regardless, great job...very informative at the pragmatic operational level. Thank you!
You bet and thanks for all the great feedback!
Great explanation - Thanks
Very good video!
Good info.
Fantastic tutorial. Thank you so much
You bet!
This is the best explanation I've seen on wiring 😂
Thx!
Well done
Excellent review
Thanks!
Hi, really great explanation on the wiring setup, i have a question regards to the flexible solar panel to the solid structure panel, do know if they produce the same amount of of power ?
Great video. Thanks! You said in the beginning that you would talk about the disadvantages of parallel and series set-ups. What happened to that discussion? For example, aren't panels combined in series susceptible to shading problems where the no power is harnessed if even one panel is shaded?
Awesome video....what gauge wire did the electrician use to install the smart panel 12feet from the existing panel?......I would install mine about 25 feet from my existing panel.
Very informative!
Thanks!
Thanks for your update, I have 3 265w solar panels and 2 190w solar panels how can I connect them
Nice job. Helpful. Something to add at the end would have been solar panel tilt into the sun (beer can on panel leaves no shadow ) to see the max power you would get. Thanks for sharing
The old "Beer Can" trick. What project would be complete without at least 1 beer can 😂. Thanks for the feedback!
Beer??? Where?!!!?!
Great, tks you help me decide !!
Excellent !!

I have 3 x 100w. Can I run series - parallel on them? 2 x 100 in series and the other one in parallel
Thank you
Your awesome. Thanks
Thanks!
Hello great video. I was wondering if you can combine 24v panels with 12v using series parallel? I have 4 12v panels and 2 24v. This is on a 48v system, controller can take 150v, 3.2k watts, 60amps. Question is more about the panel voltage than anything. Obviously the Voc and all need to work first. Thank you
Your videos are very informative and easy for anyone to understand. You break everything down for the layman and I appreciate it. Liked, subbed, and I’m binge watching your content. Thank you for the work you’ve put in.🫡
Thanks so much for the feedback and support!
I have the two Delta Pro connected to a 30amp connector via the hub.....what third party rigid solar panels do you recommend for that system
Muchas Gracias por tu ayuda men
Love your video, so clear with the diagram. Is there a limit of length for the cable between one solar panel like the 220W -Ecoflow and the Delta 2 Max and is 10AWG preferable to 12AWG? Thank you.
10 Gauge should have less line loss but I don't think there is a set limit on the length of wire. I picked up 10 gauge to make my own custom extension cables. Here is the one I picked up last week amzn.to/436SdE7
thanks for the video! You have giving me good info, just trying to keep a frig, gas stove, a small chest freezer. Would like to get a washer on it and some heat. But that may not work on a Burnham gas steam boiler. But would like to get an eco flow generator for the house to power just what I needed during a black out if it happens.
"Prime Day(s)" is tomorrow and the 12th. Keep an eye out as there might be some really good deals on EcoFlow, Bluetti, and some of the other larger brands in the portable power station / solar generator space.
I used a killawatt ez meter to plug in each appliance I wanted to know power usage over 24 hours.
Best 30 bucks spent. Oh and tiny dorm fridges don’t reach take out food safety temp quick enough…..66 watts when cycling but for beer rather than food in shtf.
I love this video so much I have a question can you help me understand open circuit am I correct in visualizing like a complete circle like it's a complete circuit like a loop is that what you mean by open circuit
Great video and explanations. What is the orange tool used 6:25 into the video called and where can it be ordered ?.
Didnt find it at the provided Amazon link. Please advice as I need it for my Ecoflow setup.
It would be nice to see the effect of shading on one panel in the case of series or parallel connections.
Exactly what I was thinking. ❤
Thx
Outstanding job ! Lets talk cable gauge . . . Recently melted my 10 AWG gauge 2x50' line MC4 connector's where they meet for some unknown reason? At the time only one 430 watt solar panel was connected on a clear sunny day? So may I ask your opinion why this happened and what gauge do you run 8 or 10 AWG?
I read the comment below that you agreed that these panels' specs aren't the optimum choice for the Ecoflow due to the Eco limitations. I just got the Pro and would like to know what specs to look for.... and avoid..... in four 400 watt panels to get the closest to 1600. And your drawing is the clearest wiring explanation yet - I haven't understood ANYONE else! Thank you!
What makes a setup easy is if you can just wire panels in series and get close to the maximum solar input wattage. For these panels I was maxing out on the voltage which meant I needed to start wiring in parallel. The challenge would be to find a panel with higher current output (closer to 15 Amps) and lower voltage output (closer to 35 V). Not sure those panels exist 🤷♂️
I just purchased an EcoFlow delta pro and four 415w bifacial Hyperion panels, they’re VOC is 37.45 and Amps are 14.02, in theory I could run these in series and my volts would be 149.8 , just shy of the delta pro’s limit of 150v. Is this a bad Idea get so close? Or am I better to run series-parallel and lower my volts to 79.9 and bring my amps up to 28.4?
And if the delta only pulls 15A from that set-up wouldn’t I have to re-work the watt/law and calculate 15A X 79.9= and only get 1198.5watts??
@@Mr.Excitement-gn4evHi, I have the same issue). Have you fixed it already? How is looks your configuration? Thanks in advance
Great video. Something I was hoping you would mention is that in series, if even one panel is obstructed with shade, it reduces performance for the whole string. Parallel wiring allows each panel to fall into shade separately. But again, there are pros and cons to each approach. Also, a general statement, is that panels need to be kept clean to perform as rated. Hosing then off or even brushing them is good maintenance but hard to do on the roof. For this reason, I am very interested in mounting at ground level, or somewhere I am comfortable reaching on a ladder.
Good call on the shading issue when it comes to series. Thanks for the feedback!
Wouldn't you start using things like micro-controllers when getting to these sized systems anyway? Over 1000w feels like a tipping point...
@@sloanNYC The Ecoflow Delta Pro is expecting Direct Current (DC) power flow at its solar input. The power stored in it can then be output as Alternating Current (AC) by going through the inverter internal to the Ecoflow. It wouldn’t make sense to do micro inverters at the solar panels themselves because that would be creating AC power flow before reaching the Ecoflow box, which is only set up to receive DC at the solar port. For an Ecoflow, a traditional string of panels connected in series or parallel is really what it was meant to work with, whereas micro inverters would make more sense in a permanent home installation into your house wiring, which is also AC. The Ecoflow Delta Pro is intended for up to 1600 watts of solar input in DC, but it’s maximum volts specification makes that a bit difficult to reach. It’s more of a ‘portable’ setup that can serve a role in home backup, too. To your point, however, if solar panels were equipped with micro inverters and sent AC power to the Ecoflow, maybe that could feed into the regular AC charging plug just like when it is plugged into a household outlet to charge, and that charging rate would be faster than the solar input. Just not sure if the performance increase would be worth the extra hardware costs. Interesting concept, I will be thinking it through some more.
@@natehowe7975 Totally understand. I’m just thinking once you go so big on solar you really aren’t portable anymore and your needs may fall into a weird gap. LOL.
@@sloanNYC That’s the journey I have struggled with. After a long power outage I started thinking about options to prevent it happening again. My design goal for the project has been to keep everything portable enough that I could take it with me to a friend’s house if they were the one having the outage. I try to stop myself at very permanent installations that need to stay with the home, but I am also not trying to run the whole home, just critical loads. By limiting my consumption plans to a few things like refrigerator, furnace, and window AC, I can look at smaller generation. If I planned to keep central air conditioning online that would require an entirely different plan. I got an Ecoflow Delta to experiment with and loved what it can do, given that it is pretty small. Then I got into the Ecoflow Delta Pro which can flex between portable (trunk of SUV / RV) but can also be useful to a house. I do have some portable panels I can stand up in the yard in an emergency, but I am wrestling with the idea of permanently installing panels on the roof. Given that my project is more focused on redundant options than offsetting the electric bill, I haven’t gone forward with roof panels. In the meantime, I can run a lot from the EcoFlow Delta Pro through the first day of disruption, then I can refill with portable solar panels and/or a small Honda generator that I modified to natural gas / propane / gasoline.
Some folks use MPPT others Voc and Isc (I use the Voc/Isc for fear of hurting my equipment). Which is correct?
What inline fuse do i get , 15 amp or 30 amps ?0r 40 amp. ? And hey can you tell he where you got the Helien 360 panels i cant find them anywhere, they are kool .
may i ask what is the total current going into the ecoflow unit ? 13.3 a ?? thanks
I have two Ecoflow 100 watt rigid panels and a delta max. I want to be able to operate basics during an extended power outage or a tiny window AC. What else do I need to have? I’m going to get two more panels. Any advice would be helpful.
So just using the ecoflow wiring kit and the ecoflow delta pro will not be automatically optimized for lets say 2 400 watt portable panels?
Another question (please): Your EcoFlow handles over current, but not over voltage. I have cheap grid-tied inverters with limiters that have a max of 1000 watts output each. They have very low voltage maximum input so my 320 Watt panels can not be put in series. I have a number of them wired in parallel so that I can have at least three panels per inverter. I would like to put four panels per inverter but it would be over the max current input the inveters are rated for. Can I safely "over-current" my inverters by adding the fourth panel without fear of hurting the inverters as they will "current limit" and protect themselves? (Assume I have all the fuses, disconnects, ...... in place). Thank You!
Easiest would be just to use one panel. Qcells does make a 475 to 495 watt 78 cell. Which means 45 volt STC at MPP. It should also be ok for use at -30 celsius (Canada) as the open circuit should be just under 60V, which many all-in-ones do not exceed.
72 cell is ok, but I find that it does not match as well as 78. If always in hot USA, it actually makes more sense to use a 84 cell, if such a thing exists.
There are many benefits to using just one ginormous panel, ease of connection, no extra wiring or fittings and no voltage insertion losses.
Nice, If I went that route I would probably grab 2 of the ginormous panels and just wire in series since the voltage will still be under the 150V max on the EcoFlow and no additional wiring needed. I want to place this setup in a off-grid shed where I have some outlets, lights, and battery chargers for the outdoor electric power tools.
I am a newbie to this. I got 5K Growatt invertor 48v and looking at getting 10 400w Canadian SP . what would be the best way to run them? thanks for your help .
Hello.
I have three flexsolar 360w foldable panels.
I can't set them up in vertical position because being foldable they wouldn't hold up a 90 degree angle.
My question is, if I set them up in horizontal position, would it be the same procedure to connect them in series?
🤔
could this also be done the same way if you were using 2 100 watt and 2 150 watt panels together?? THX
For the Ecoflo pro unit you had, you would have been better selecting your panels for your power system. 3 540 watt panels in series would have optimized your voltage at just under 150 volts and 11 amps of current. That in theory will give the ability to maximize your 1600 watt desired input. But it doesn't give you such a great parallel, series educational video. It might have been good to explain how to design your system for optimal function.😊😊
Thanks, clear explanation… I have 3 of 400 watts… can use 2 in series and last panel connected to rest of open wires? Thanks
What is the Open Circuit Voltage of your panels? You should see the Voc called out on the data sheet usually located on the back? Also, are you bringing your panels into an Ecoflow Delta Pro?
Hi, wondering was there a inverter used ?
great..Thank you.
You bet!
@@everydaysolar best regards from Europe... From CZ
Are you using both inputs on the ecoflow unit or all panels into 1
I bought EcoFlow balcony solar power plant with 3.600W Delta Pro storage, 800W inverter and 2 x 480W Bluesun (37.1V) solar panels. When the power plant is connected throw inverter to the network, can I connect the third panel, which is not part of the solar plant ,with a power of 480W (37.1V) directly in the XT60 input to the Delta Pro for extra charging?
Great explanation!
I got stock with my EchoFlow Solar panels, can’t find installer. Looking for licensed installer for my already acquired 8each 400 watts regid solar panels on my home.
Are you trying to tie into the grid or just into a Delta Pro?
When doing it in either way is it important to make sure your solar panels Watts need be the same? Example: Could i hook up 160W with 100W panel? just subd your channel.
I am guessing the parallel comfiguration performs well in cloudy conditions
Well done, this was great.
Thanks!
Help me understand what just happened here, you have 4 panels in series but it’s over in voltage. Now you have the same 4, 2 sets in series connected in parallel, how the does voltage drop? And how are the amps not over?
Lik'd and Sub'd for this high quality content.
Welcome to the channel 👍
Great video!! Quick question.I have an Anker F3800 with 32V-60V at 25A (1200W Max each input) Could I use BigBlue SolaPowa 400 watt panels in parallel? They are rated at 61.5V at 8.2A slightly over the voltage. Or would this harm my power station? Thanks.
Bummer, the problem is it would probably work 99% of the time but maybe on a cold day you might reach above 60V. I am not sure how Anker handles this as some units shutdown the solar input but others units can be damaged. Probably should be careful using that combo.
Yes, RAID10 my solar panels.
I have 4 100 watt renogy panels...can I use that brand to charge an ecoflow?
My brain I dunno what's going on usually I understand this. But I'm looking for my specific situation I guess. I have Delta 2 Max. I bought two extra batteries, I have two 220w bi facial panels from Evo flow. How would I maximize this device in solar output. As I want to buy more solar for it. This is for my work shop where power is an issue
Nice vid 👌
Could you explain why you can exceed the rated 15 amps of the delta pro? If you had a long term setup would there be any negative things associated? How would rate for inline fuse?
I was hopeful for this explanation as well.
Another waiter for such an explanation...
Another waiter...
now we need a waitress.
The short answer is amps are pulled, volts are pushed. So, if you push too many volts to the ecoflow, it won’t accept it. If you make too many amps available to the ecoflow, it doesn’t matter, it’ll just pull 15.
@@ConorLennon Thanks. Do you know why they're recommending inline fuses for parallel set-ups to prevent exceeding the 15A rating?
Hello. Thank you for the tutorial on this. It was perfect. How do I get around my scenario. I have an RV with 3-180W panels connected to a 40A solar charge controller charging 2-200AH Lithium batteries. How do i get the solar power to the Delta pro in this scenario?
Do you just want to charge the Delta Pro or are you trying to integrate it into your existing setup? Do you currently have an inverter connected to your 2 X 200AH batteries?
@@everydaysolar There is a Xantrex 1000W inverter in the system that runs nothing but the residential fridge. I ultimately would like to incorporate it into the existing setup. Unless you think there is a better option or setup
can anyone tell me, what if you charge and also drain at the same time, if the productive current pass through batteries before drain ?
I mean, lets say we charge the Delta 2 with 500 Watt, and at the same time we ask for 500w power. Does the current pass through the batteries or this is working like an online UPS, means, im taking what i am producing, if the producing current its higher, then and only then, the batteries will get that current and charge.
off topic a little, i have a ecoflow 1000 delta 2 can i charge my jackery 500 with it and what would i need to do that thank you
Sure, you would just use the 120V wall plug from the Jackery in the 120 20-Amp outlet from the Ecoflow.
I got myself in all sorts of mess with mine. I have a 400W, 2 x 200W and 4 x 175W and I have 2 X Delta Pro’s with the Powerstream Inverter so I can input 1600W in each Pro and two individual 400W inputs on the Powerstream. I only want to use one Pro at a time with the Inverter plugged in powering the flat (apartment) while the other one charges ready to be swapped. I’ve gone through different solutions via AI and it told me not to connect all the panels because they’re different voltages but I’ve seen it done in other YT videos and the people didn’t seem too bothered about it, I just don’t want to cause a fire first and foremost. I have 700W (4 x 175W) going into the Pro that’s not being used and 400W going into the other Pro via the inverter but I’m unsure about connecting the other 400W (2 x 200W) because they’re 2 x 23.?v rather than the
Can't you wire everything up in series then connect the solar array to a magic box that'll +-V and +-A to be within sweetspot?
Depends on what you are plugging the panels into. For instance the Delta Pro has a 150V volt limit so can only do 3 of the 360W panels in series to ensure you don't max out voltage. Depending on the hardware if you go over max voltage you can fry the unit.
I own two EcoFlow Delta Pros. Is it necessary to use individual XT60 cables for each unit, or is there a method to link both XT60 ports on each EcoFlow Delta Pro to a single cable?
Hmmm, I just use individual cables one for each unit.
Common sense approach to the info that I need i have the same eco flo
Nice, best of luck with your setup 👍
Should I install a pv quick disconnect going to my Delta pros?
I don't just because I have the cable readily accessible for disconnect if needed.
Does the D2Max have the same safe guards, as the DP. As far as putting more volts, more Amps, and just getting zero charge? Until you get it within specs. Don't want to burn up the MPPT controllers
Yep, I would just make sure you stay under the max voltage when you add up all of the Voc to be safe. The current will clip off at the max without issue.
@@everydaysolar In which case would you still need the inline fuses for a Delta Pro? Thanks
So. No matter how you configure those 4 specific solar panels, you're still never going to achieve their full power potential into the EcoFlo. Because either the total voltage (in series) is too high, or running them in parallel results in unused amperage. So, I'm assuming a better option would be to properly size your solar panels and battery power unit to avoid lost power.
That is exactly correct. These panels are for another project so I definitely didn't purchase them sized for the EcoFlow 👍
good video. Of course 2x3 panels would get you much closer to 1600W max.
That’s my set up DP with 3s2p ….2 strings loops. I have used panels 350w 48.2v …..bought panels for 75 each. Sounds silly but I cut almost 2 dollars off my bill every day till I die or equipment failure so eventually in 5 years I should get some profit. Gluck
