Maximizing the solar charge capability of a portable power station is critical to designing an off-grid system. With a little knowledge and planning you can select the right panel or panels which will match the voltage range and current limits of your system. I will walk through an example trying to max out the 500W solar input capability of the ECOFLOW Delta 2 both using 100W panels and then switching over to larger 360W panels.

Very well explained and EXCELLENT content.
So helpful for new solar generator users!! Thank you !! I have a delta 2 and have been struggling to understand how to get close to 500w solar input and staying under 60v.
Great video! It's awesome to see how the ECOFLOW Delta 2 can be charged with solar power. If you're looking for a portable power station with similar capabilities, I highly recommend checking out the Segway Portable PowerStation Cube Series. It has a massive 5kWh capacity, fast recharging, and a durable armor design. Perfect for outdoor adventures and backup power at home!
You and me both. This is a very commonsensical approach to this important step. Too many options exist and this cuts to it.
I have the Delta 2, among other LiFePo4 tech., and I love it. It'll be the unit I grab if I need to go in a hurry. The way things are going, I'd highly recommend people be getting prepared, just in case. Besides having a very portable power station, at least one flexible / foldable solar panel is also highly recommended. Besides food, water, and protection, having electrical power is near the top of the list.
A very informative video. Thank you.
That's great to hear that you love the Delta 2 and it's your go-to power station! It's always important to be prepared, especially when it comes taving electrical power. I appreciate your recommendation for a flexible/foldable solar panel too. If you're looking for another portable power station option with impressive features, I would highly recommend checking out the Segway Portable PowerStation Cube Series. It offers a massive capacity, fast recharging, versatile sockets, and comprehensive protections. It's definitely worth considering for outdoor enthusiasts and RV lovers like us. Happy camping and stay powered up!
Thank you for sharing your experience with the Delta 2! It's great to hear that you love it and find it reliable. I completely agree with your recommendation about being prepared, especially when it comes to having electrical power. The Segway Portable PowerStation Cube Series is another excellent option, with its massive capacity, fast recharging, and versatile sockets. It's definitely worth considering for outdoor enthusiasts and RV lovers. Stay prepared and enjoy your outdoor adventures!
Yessir, MyTube 4Utoo! I bought the Delta 2 and the FLEXIBLE 100 watt SPs--mostly because they can be "hung" vertically in my south-facing windows even in Winter. Power-up with the SP inside the home!
What’s up with the bots??lol
As I said below, this is a well needed overview of a grey area. Thanks for putting this together. You got an additional, well deserved sub.
are you gay?
Thank you! By far the best explanation of series , parallel and a series/parallel solar.
Thanks!
A greeting from Slovakia. I live in a block of flats and the panel is attached to the railing on the balcony. I bought a victron energy 175 watt solar panel for my Delta 2 and at the right angle to the sun I get 140-155 watts. The panel is polycrystalline and cost me 125 euros new. Now it costs around 150 euros. If I do not position the panel correctly to the sun, then around 90 watts. In my opinion, it is worth buying two pieces of 175 watt panels and connecting them in parallel and you get 350 watts. Realistically and with a good slope and a time interval of 6 hours (from 09:00 to 16:00) about 280-310 watts. It is cheaper and more efficient to buy fixed panels versus folding panels. Hint : i did compare charging from 34% to 100% and with 200 wat it will need 4:06 time to charge. But with 300 watt is will need only 2:48 time to charge. So massive difference between 200 and 300 watt charging.
Hey 👋 thanks for the feedback. It is really helpful when people provide details on their specific setup since we all have different needs/use cases.
You won't get 350 watts most likely in parallel as you will hit the max amps in limit. Assuming your panels have a short circuit current of around 10 amps, it will however help out hugely on cloudy days and handle shading much better than a series setup.
@@rjbfreelander2 i tester already 2 175 wat panels in paraller conection. 15 amps x 19,4 volts = 291 wats. This was peak resul in tíme from 1 pm to 3 PM.
Users have reported that Delta 2 cannot charge by solar when there isn’t enough power coming in. It will say 0 watt input until there is more than something like 25 watts coming in. This is bad for users with smaller panels or cloudy days, and basically inefficient since you’re missing out on a good part of the day.
Lol, if you are putting less than 25 watts, you are wasting your time anyway, so there would be zero reason to connect a panel to it that is absorbing less than 25 watts.
It might not display but it should charge anyway. Like with the ac. It won’t show anything under 10W but it sure does work.
You need an XT60i cable. The basic XT60 is limited to 8a. The "improved" can handle 15a. The XT60i is orange and the basic one is yellow.
Thanks for the clarification and I will be sure to call that out in the future videos 👍
You should discuss the fact that panel efficiency is reduced by 1% per year as a conservative estimate. It's probably more like 2% in places like florida where they are generating electricity 12 hours a day for most of the year. The sun takes its toll on all things including solar panels. Environmental pollution will compound the problem if pollutants accumulate on the panels blocking light.
Thank you!
You bet!
I got my Delta 2 package from Prime days and tried the Solar charging yesterday. It was a bright sunny day and I averaged about 180 W. Worked great
Nice, that is a handy setup and one of my favorites.
Me too!
Because of your video I was able to hook up my solar panels. They didn't come with installation instructions. Thank you
Here to help 🙌
Thank you for this video
You bet!
Good info.
Thanks!
is there a way to regulate the voltage coming in, to say, use those smaller silver pannels in series with the black pannels to get it near 60v 15A
Two of those 360w panels in parallel seem like a great solution if you have the panels and the space. The excess capacity providing charging even on overcast days is a win.
Yer that’s what I was thinking… say you had 100amp available would that cause a problem ?
@@beaker8501 The most important spec is the volts. Make certain the maximum open circuit (O.C.) voltage from the panels is less than the max acceptable on the solar input. For the Delta 2 the limit on the input is 60 volt.
@@Sylvan_dB what about the current (amps) can you have “too much” current ?
@@beaker8501 No. Think of it as "current is available" -- it has to be drawn or pulled. Think of "volts are pushed" -- forced to the recipient. If you don't push too hard (not too high volts) then the receiver won't take too many amps even if they are offered.
I actually own a Delta 2 Max and have been trying different setups. With 12v panels I've actually found a 2s2p 100w configuration works the best and keeps it within tolerations. I've tried doing a 3s configuration and the Ecoflow won't charge due to the panels open circuit voltage being over 60v. That being said I'd easily swap out with something that keeps it below the 60v / 15a max limitation. The Q CELLS 485W XLG103QPD-BFG gets pretty close to that. Overall you need to really read the spec sheet of any panels you're using and understand the open circuit voltage. Otherwise your EF device isn't going to charge. I've also found you're going to get N-1 wattage out. In other words if you have 400w of solar, you're going to get about ~300w out.
Good stuff thank you - keep it up. Love learning about solar.
Will do and thanks for the feedback and support 🙌
Positive Comment!!!
Do you add safety devices to panel to powerstation connection?
I wish you tried to face the panels direct to the sun and made sure the shadow was really perpendicular to the panel (example the way your delta pro was really facing the sun) you definitely would get power power😊✌️
I’m still learning about all this. Is it best to have 4 panels than 3? Can 3 not be hooked in any wiring setup? I’m looking to buy either 200w allpowers flexible or JJN solar 200w. With these panels is it best to have 4 over panel it?
Hola, tengo una duda, se puede hacer la carga solar dual, por la entrada solar y con el Microinversor con 4 paneles de 100 cada uno y por separado por la entrada solar del delta 2 con otro panel de 100... e visto en un video en ingles que con el delta Max si se puede después de una actualización del firmware.
what best config on the app to get the most time of solar charge, im using the delta 2 to power up essential aquarium circulation pumps, now i have it plugged in to use it as a ups, but i will ad a solar panel , i want to use the most of the solar power possible, ive seen in the app some spect to move to , but you recomend some best specs for that?
I have added the extra battery to my Delta 2. (We live in Hurricaneville.) Prior to adding the extra battery, the most wattage I could get from my 2 190 watt HQST solar panels was around 350 watts. Since adding the second battery, I have seen almost 500 watts on several occasions. I've done more than one double-take. As I'm no electrician or engineer, I'm a wee bit mystified. Having said that, I'm of course pleased as punch. Anyone have thoughts to share?
Hi there! I have 2 panels Ecoflow 400w and charge station Ecoflow Delta 2. Can I connect parallel this 2 panels and got 500w?
Can u actually run parallel on two different solar panels? for example I want to increase my 500w solar panel but am scared if I put another brand and power over it, it will not work. Every video I have been seeing about running in parallel is usually the same brand of solar panels. Can I actually buy a 300w solar panel to top up the solar panel that I have.
I have a 2kva power station that only accepts 500w. I have a 500w panel and a 15 meters solar wire but the problem is that any time I charge I only get max 280 watts and even in a sunny day I cant enjoy my powerstation. If I buy a 300w solar panel to add to my 500 solar panel will it work?
If I run in parallel a 300w and 500w the volt is supposed to remain the same which volt exactly will be the same is it the volt of the 500w or that of the 300w.
can I join two different panels for my powerstation
Get temp coefficient specs to understand how panels voltage will rise in cold temperatures...
Yeah, I have been digging a bit deeper on temp of panels and corresponding power output over my last few videos.
That’s the problem I had! I tried to add a third panel in series and must have exceeded the open circuit voltage. Is there no way to hook up three panels a a delta2?
Just depends on the individual panels. If you are bumping up to the voltage limit it will shutdown the solar input. Could you get another panel and setup like I did with the 4 X 100W panels?
Hi there I know you can’t go over the voltage limits but if you say doubled the current will it still operate? Or would an error come up ?
The Amperage will be throttled on the Delta 2 with a max input current of 15 Amps. You can connect up a system capable of delivering 30 Amps but the Delta 2 will only allow 15 Amps.
Glad i saw this. Had no idea it was so complicated and canceled my order just in time
I have ordered a bluetti AC180 however a friend has an eco flow tec portable panel that he said I could borrow, do you know if the portable panels all have the same connections into the battery units? thanks
No, they don't all have the same connectors. Most of the panels will have MC4 connectors and then you will need a conversion cable to connect MC4 to the connector on the portable power station. The EcoFlow uses an XT60 but I think the Bluetti is a different input plug for solar.
@@everydaysolar thanks for replying, I mean the connection into the box. So basically will an eco flow panel with mc4 work on a bluetti if they both have mc4 connections. Thanks
@@everydaysolar oh is mc4 the name of the connection into the panel. I see. Thanks so much 👍👍👍
Where the heck do you buy the Hellene 360w panels? I can’t find them for sale anywhere
I purchased them from the Alt E Store ( lddy.no/1fpoy) but I think they are all out. They have a few other options but not a great match to the 360W panel from Heliene.
yeah all I could find online was bulk orders for 10 or more. I'll keep an eye out on that link, thanks!@@everydaysolar
Hi, I have a Delta 2 Max with 2 x 410w identical panels from Canadian Solar going into each of the 2 Ecoflow inputs. Each pair of panels are wired in parallel and their ratings are 37.2 volts / 28.02 amps and 410 watts.....even in full direct sunlight (with the panels directly facing the sun square on), I am only able to generate a maximum of 850 watts and cannot reach the stated 1000w maximum the Delta 2 Max is supposed to be capable of.....I have tried the panels as singles, so 1 panel going into each input and that way I manage 630 watts maximum....anyone have any ideas on how to achieve the maximum of 1000 watts solar input ?
Your panels are the limit here. They would not produce 1000W on any inverter setup. 850W is about expected for two 410Wp panels.
What are the 360w panels resting on?
plastic saw horses
I was thinking of a delta2 with 2 Renology RSP200D
200W Monocrystalline Solar panels. (rigid)
Their spec includes:
Optimum Operating Voltage (Vmp) = 19.2 V
Open Circuit Voltage (Voc) = 23.0 V
If i get this right - the 23v is the key parameter here- so 2 in series would not overspec the delta2.
Is it as simple as that ??
Thanks for shared perspectives....
other specs:
Maximum Power at STC* = 200 W
Optimum Operating Current (Imp) = 10.42 A
Short Circuit Current ('sc) = 11.05 A
Module Efficiency = 19.2%
Maximum System Voltage = 600 VDC
Maximum Series Fuse Rating = 20 A
Yep, placing those 2 panels in series would mean worse case 46V with a little buffer to the upper limit of 50V for the Delta 2. I think that would be a solid setup for the Delta 2 👍
@@everydaysolar Thanks - appreciated!
I have the exact same ecoflow. Where did you get the 360 panels. Will it hurt it to be hooked up all the time
I got the Heliene panels from the Alt E online store lddy.no/1fpoy. Their stock of panels rotates often but you should be able to find similar size panels currently available. You need to make sure you stay under the max voltage or the EcoFlow will shutdown your solar input and you might miss out on charging during the best part of the day. Current will be limited by the EcoFlow.
I got the ecoflow delta 2 extra battery 1kwh . 1800wtt can I use any solar panel to charge it like 200wt solar panel@@everydaysolar
Can you power something while charging from solar panels?
Yes with Eco Flo you can.
From what I'm seeing here, it's okay to exceed Delta 2 parameters for voltage, amps, and watts without doing any PERMANENT DAMAGE to the Delta 2. When you exceed voltage you get no power. When you exceed watts and/or amps it just uses up to it's max of 500 watts / 15 amps and the excess has no adverse effect on the Delta 2?
Yep, don't push the voltage close to the 60 volt limit because if you go over the Delta 2 will shutdown the Solar input and you will get nothing. When it comes to Amps the unit will just "throttle"the Amps at 15 even if the panels could deliver more. I like the second setup much more and if I were installing this in a shed I would do the 2 X 360 Watt (or similar) in parallel.
@@everydaysolar Thanks
So 2 x 300 watt panels should be fine i dont own the delta 2 yet or 300 watt panels but hope to soon
Yeah, just make sure you keep the voltage below the upper limit for the panel(s) selected.
The video is generally good.But while you explained the Siri's connecting very well.I didn't hear you explain the parallel connecting that well. The only time you've gotten to parallel, it was only for the series parallel hybrid and went quick.
Which is too bad because that's actually what you needed.And what I need because I have 2 250s.
I’m trying to see if I could wire 5x 100 watt Ecoflow panels into a delta 2. Could I put 3 in parallel and then series it to 2 in parallel?
Did you ever find out about this?
@@JoshsEDC nope, ended up just doing 4 100 watt panels
@@ngk330 thanks bro
Do I have this right _ if I exceed the maximum VOLTAGE limit of the power station with a solar array I could blow the power station up, but if I exceed the maximum amount of solar CURRENT the power station will self regulate and there will be no damage - ?
Yes, although with most power stations they will shutdown the solar input above the voltage range to protect the unit.
Why Eco flow set up is for grid down times not off grid. I believe 90% of these type of customers should be thinking more of the line of grit down as opposed to off grid.
Why?? Maybe people are looking to use it for off-grid?
Can the Delta 2 handle 4 110 watt panels in parallel ??? I'm thinking of getting a Delta 2 but want to be sure I have everything I need to hit the ground running... I'm a newbie. The only bad question is one not asked. Thanks in advance!
I just ordered a Delta 2 today! And have them same question. I think from what I’ve researched aslong as the voltage is right across all the panels it should work but the Delta 2 itself can only take 15Amps max so hooking it up to a 30Amp solar array wouldn’t be optimal that’s more Delta Pro territory. U still can charge it with a 30Amp array but the unit will only allow 15Amp max in. My plan is to go with 2 200watt panels but I havnt decided who to buy from yet.
It depends on VOC volts open circuit of each panel.
I Have four 100w panels and I need to have two in series and two in parallel to stay under the 60v.
@@samuelfox8126 I'm planning on 4 Ecoflow 110 watt panels. When you say two in series and two in parallel, do you mean 2 pairs of series and then parallel the two pairs of them all together?
@@reese9276 yes, that's how I did it and it works for me. Hopefully those panels are under 7.5 amps each so you don't lose any capacity by the ecoflow 15 amp cap.
@@samuelfox8126 From memory, I believe they're about 6 amps....
Here are a few questions for all the pro's out there. Im looking at selling my house and going boondocking out in the wilds of southern British Columbia. I will be working online with Starlink, and running an average gaming laptop. I added up what I believe my watt hours per day would be... not confident in my numbers... 10,000 watt hours / day sounds crazy to me! but I want to set up a solar, wind generator hybrid system. I also want to hook in a Gas generator/inverter to recharge the batteries if I need it. Ive been looking at these Power Queen 12v 200 ah batteries that can handle up to 2560 watt loads, run in parallel they will give me 12v 400ah and handle up to 5120 watt loads??? IS THAT RIGHT??? or is it still just going to handle 2560 watt loads??? Im just running back through the math again and seeing my max load with everything running at once should be less that 1000 watts.... So here is where I really need help. How many 200 watt solar panels should I get? what size charge controller? Im guessing about a 2000 watt inverter should be good? AND HOW DO YOU WIRE A GAS GENERATOR TO YOUR CHARGE CONTROLLER!!! Can I some how just wire the gas genny into where the solar panels hook in and have diodes preventing the power coming from the genny into the solar panels? Am I over thinking this? I do have 2 gas generators right now, both small, one does 880 watts, one does 1200 watts. How would you hook them in to recharge your solar bank?
There’s no way that setup pulls 10k watts a day unless you plan on gaming 20hrs a day. You got a lot of research to do. You’re better off just buying a premade kit like an EcoFlow Delta Pro or Anker 767 with extra battery.
Will Prowse Channels covers all this. His channel will help you understand the limits/possibilties of solar.
Will it keep a refrigerator running by itself
It will, the Delta 2 can run my refrigerator continuously for about 11-12 hours.
and what will happen when there will be 500 + watts?
If you go over on current (Above 15 Amps) it will just "clip" the current at 15 Amps and not allow anything higher. If you go over on voltage the solar input will shutdown and not allow any solar power in. That is why you do not want to push things on voltage.
And what will be 500+ watts? what will happen? 360+360=720 (550/600/700)
In my country, the support tells me that it is impossible to graft as it burns, only 500. But it seems to me that they are not saying anything.@@everydaysolar
I just bought a brand new Ecoflow Delta 2 Max with 2 ports of 500watts each and my question is which adapter is the right one between XT60 and XT60i for this Delta 2 Max ?
XT60i
33 panels seems to be the "default" setting for number of panels. This is wayyyyyyyyyyy too many panels. This drives the istallation prices up and extends the payback period significantly. In order to install that many panels on most houses it will require panels to be placed on the north facing where they will never pay for themselves. Homeowners would be best advised to limit their panels to as many as possible on the south side.
If they dont have a south side then they should purchase a house that does. Solar panels are NOT for everyone. And they are not meant to be a replacement for the grid unless you are installing batteries, which most do not.
Over generating KWs is a bad idea. The power company will pay you pennies for all of you excess KW's that you will generate if you put up 33 panels.
And in winter time when the sun is really low, no matter how many panels you have, you will not generate sufficient energy to pay for the cost of the panels. And of course, if you live north of the mason dixon line, your sun exposure is limited for two reasons. 1. Crappy cloudy weather most of the year. 2. Slope of your roof is not sufficient to get direct rays from the sun. For maximum output of the solar panel the panel must be perpendicular to the sun. In D.C. for example, the panel would have to be 31 to 46° for 9 months out of the 12.
Someone needs to tell the truth about solar companies sticking it to unsuspecting homeowners. 5KW is all 90% of homeowners need to give them the savings that they want.
Ahhh good Ole grid tie system, so when the power goes out you are still without power.
