Ecoflow Delta Pro - Using an AC Switching Power Supply to extend your Delta Pro

- In this video, the 3rd so far in exploring how to power your Delta Pro with an external battery bank (and thereby extend the overall capacity of the Delta Pro). I look at using a switching power supply. The supply converts from AC into DC which can be used by the Delta Pro's xt60i solar input port. Although inefficient (effectively converting from DC to AC and then from AC back to DC), it does seem more reliable and safer than the DC to DC Boost converters I tried in part 2. Watch the whole video for more details.

Thanks, just ordered one and using it to pull from my Ioniq 5 V2L adapter to utilize the 77Kw battery.
77Kwh is a LOT of capacity! :) Definitely on my wish list.
I want to do the same for an EV6. How is it working for you Michael?
@@hlgenius I haven't had the need as of yet, but in testing it worked just fine
@@michaeldelrossi9532 Nice, please keep us posted
Could you conceivably output to MC4 Red/Blk connectors if you had a unit that accepted mc4?
I want to thank you. This seems like the exact solution I've been searching for. Please continue to bring us content like this. 🎉🎉
Do you have the DC from the AC/DC inverter split into each of the Delta Pro's solar inputs ?
Right now its just feeding into one. My goal is once I obtain my solar panels and greater productivity is to try to feed into 2 Delta Pros from the external battery bank and the EG4 Controller. Will definitely update once I get to that stage.
That’s exactly what I’m trying to do for my Delta pros. Do you have an idea on how you’re going to implement both solar inputs from one external battery bank and 1 eg4 controller?
Could you split the AC to DC cable in a 1 to 2 configuration going to each Delta Pro? I used to do something like that inside my old desktop towers using a splitter power cable from the power supply to power two SSD drives. Not sure if you can do that here. Or whether it would cut the number of watts to each Delta Pro in half from 1600 to 800 each power station.
But I do like this option very much.
Great idea and video! Can you link the new power strip you found to connect to your eg4? Thanks for sharing
I'll do a video update soon but what I wound up doing instead was just wiring an electrical outlet to my Eg4 so I could plug in whatever I wanted.
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?
Just clicked the link, it states a output of 18amps. Doesn't that exceed the 15a max? Or is the pro different from the pro 3? My high end on the delta pro 3 has a 150v 15a max on the high and a 60v 20 amp on the low. What could I use in its stead to input the most wattage. Struggling with so many options here
It's fine to exceed max amperage, voltage is the one you have to be careful with! Think of current (amperage) like a river passing by, it could be a small little creek or the massive Mississippi, your Delta Pro will only take from it as much as it needs (15a). Voltage is the velocity of the river...it can overwhelm your DP if its too high. Amperage is fine to exceed, you could do something with 1,000 amps and your DP would still only take 15a from it. Hope that helps some!
The Delta Pro only pulls 15A. 80V X 15A is 1200 watts....what you are getting. I am using a setup like this as a backup to the backup. Using the 30A output on my old gas generator, I power 2 units like this. I only have one Ecoflow generator that I like to use on my leg my HVAV is on so I have uninterrupted nights. The issue is that ya can run the AC inverter on the Ecoflows with the Connection Hub AND charge from AC. So if my panels aren't producing, I fire up Ol' Trusty and put around 1200 watts to each. Learned several things from you b4 settin up my system. Thank you!
Can Not run the AC hub and charge from AC at the same time.
I like this option given the DP's limitation to accept AC wall charging while connected to the double voltage hub. One question - why did you use the 80V /18A switching unit instead of the available 90V/16A unit? I believe that would allow you to charge at a higher incoming wattage rate. Your video shows 1200+ charging wattage presumably due to the DP's 15A limitation. The 90V/16A unit should deliver closer to 1400+ wattage charging to the DP.
Hmm, I have a question. Why not just use the AC plug that comes with the DP and plug that directly into the power strip coming out of the inverter? I think that would give you more like 1500w charging. I have two DP's and during power outage I run a GENMAX Portable Inverter Generator, 3500W Super Quiet Gas or Propane Dual Fuel Portable Engine with Parallel Capability, Remote/Electric Start when it is too cloudy for my solar and that will charge both DPs at over 1500w from the AC from the generator.
Fair question! It's because when the Delta Pros are connected to the smart home panel via the infinity cables, both the AC input and output ports are disabled. Its a Ecoflow Delta Pro limitation.
@@DanielGoodwin-jq1ocQuestion for you. If there is a power outage wouldn’t the Delta Pros automatically re-enable the AC input because it will sense that there is no power coming from the Smart Home Panel? I would love to know the answer. Maybe you can test this by turning off the breaker in the house mains that is used to charge the Delta Pro via the Smart Home Panel.
No, unfortunately is does not. It disables the AC input/output when you connect the infinity cables. Now, of course, during an outage or emergency, you could also quickly disconnect the infinity cables and certainly use the Delta Pro as a standalone unit. However, that really isn't the intended purpose of the DP when you combine it with the Smart Home Panel. If there's an outage, the panel will pull from the delta pro(s) and their batteries to keep power on in your house. If you have solar (or really any DC input) into the Delta Pros, you can continue to feed the delta pros while providing AC power to the house.
@@DanielGoodwin-jq1oc I think I have figured out a way to get around this. That is to build my own 240v hub. Bringing the output of each DP 30 amp output into a small box and connecting them together into a 240 out plug therefore bypassing the infinity port altogether
That's an interesting solution! I'd be eager in hearing how that works out for you!
A little off topic but can I please ask. I just bought a used Delta Pro without an AC cable and saw once somewhere that it was 14awg with a warning to not use anything else, and can't find that info again. The 'official' AC cords are sold out on Ecoflow but don't say what the awg is anyway and I want to buy the right thing. But second question, would an 18awg would do any damage?? Thank you!
I would not recommend an 18 awg cable. Usually, (if you look on Amazon for example) they will be rated for only 10 amps. If you don't limit it, the Delta Pro will try to draw a lot more than that and it could melt your cord or worse. Now, you could use an 18awg cable and turn the switch on the back to "slow" charging (400 watts I think?). However, I'd recommend just looking for a good 14awg or better cable. For example, this one would probably work well:

I am looking for a reverse solution. I want to power 12v AC (40-80A) with 2 ecoflow delta 2 max. I am looking at a 24V 50A 1200W DC Switching Power Supply Adapter PSU AC 110V / 220V-DC 24V Transformer Adapter found on amazon. Is this possible (is it safe)? Should i connect the AC direct to the power supply or add a 24v lithium battery and then connect AC to the battery?
I have a few questions based on what you've mentioned. You said you want to power a 12v AC but are looking at a 24v 50A 1200w switching supply? I think you need to look for a 12v PSU. The Delta 2 can definitely output the range you need (480-960w) so that won't be a problem. You just need to make sure you get the right AC/DC switching power supply.
@@DanielGoodwin-jq1oc Thank you for responding. Do you offer any kind of consultation services? I’m looking at 24v because the AC can do 12v/24v (its a truck (18 wheeler AC - see amazon). From what I learned here on youtube 24v is better than 12v due to wire cost, efficiency, etc. for can life.
Got it, that makes sense now. Yes, in that case you should be able to power a 24v AC/DC PSU no problem with a Delta 2. However, for how long will be a question. If you have a recharging source (solar, alternator etc) then you can probably go for a while. If the AC is running continuously at 24vx40a=960w/hr then you'll deplete the Delta 2 in about an hour (1,024w) without additional charging. I'm just a handyman myself, I can't offer consultation...not qualifed! :) I do these videos just so others can see and learn from my mistakes and hopefully a few successes.
@@DanielGoodwin-jq1oc I have Ecoflow Delta 2 max and i just bought a 2nd battery, which should give approx 4kw. I also have the 800 watt alternator charger. I can charge it in 1-2 hrs. Nobody except you so far is talking about these power switching supplies so I’m really unsure on how to setup. All vampires life content are using more expensive electrical setups with different components. I’m a trailblazer trying not to set my equipment or van a blaze! 😆
if i plug this power supply into any outlet when i am in whole house mode on my dp units does this work. can i charge using my own outlets and net anything. if i have an external source for this power supply i can see some reward but can i supply my own power while in 240 mode with ecoflow. it would seem practical to recharge using a wall outlet when not in 240 mode and ecoflow is off line. in a complete power outage i could not recharge the delta pros unless i used my whole house outlets. i cant get my mind around this. pls help.
I'm not sure I follow the questions here. Mainly, I would recommend pairing a Delta Pro with a solar panel(s) for charging/recharging it when you don't have AC available.
Our EcoFlow Dual Fuel generator charges the Delta Pro via DC direct. Is that input useable for your purpose?
Yes, that would definitely work and is a good pairing with a Delta Pro. In my specific case, I'm trying to add stored battery capacity to my Delta Pro system by using an external battery bank but yes, the Ecoflow duel fuel generator is a good way to extending your Delta Pro.
Another question as I've just subscribed to the channel. Do you have 2 external EcoFlow batteries on each of your Delta Pro's ?
For my 120v single phase circuits, yes. I have 2 Delta Pros connected to a Smart Home Panel that runs all of my home's single phase circuits and each Delta Pro has 2 external batteries connected to them for a total of approximately 20kwh of capacity. My split phase 240v circuits are on a different Smart Home panel powered by two delta pros that do not have external batteries because I went down this path of using an external battery bank.
I have a question. Has anyone figured out a good way to charge up a battery bank using the DP instead of using their smart battery?
You want to charge an external battery bank from the Delta Pro, correct? You should be able to use pretty much any AC battery charger for that. If your Delta Pro is not connected to a Smart Home Panel, just plug the charger into one of the front ports of the Delta Pro and it will charge the external battery bank. If it is connected to the SHP, just plug it into any outlet that is on a circuit powered by the Delta Pro and it will charge the battery bank. If you want to use DC, you can find a model that uses the Anderson DC port on the side of the Delta Pro but you will be limited to charging at 360 watts (12v x 30 amps).
Sorry to bug you but is this solution still working for you? Thanks
Yes! I was going to do an update video after about a month. So far it has been working reliably each day. The EG4 controller/inverter charges up the battery bank and once there is enough power in the battery bank it powers up the switching supply automatically which feeds into the Delta Pro. I need to beef up the solar array feeding the controller and battery bank because right now its probably a little undersized. I haven't done that yet because I wanted to make sure it kept working successfully.
@@DanielGoodwin-jq1oc Thanks for the response. I have been living in a 65' trailer and that is why I bought the Delta pros last month . I have been trying to use them but with two 1500 btu air conditioners and using the multi port hub I didn't have a way to connect my 3500watt generator so I only got 1.5 hours of use before the battery. I just bought initiated the purchase of a new house near San Antonio, Tx so I have thinking of selling the delta pros after only one charge cycle and a firmware update. The reason being I want to do a DYI Signature solar setup with 6 48v batteries and such So, I do not need to worry how to set up this charging of them but just getting my money back out of them. I do appreciate your channel and you help.
With respect to AC charging when a user is using a Double Voltage Hub (DVH), it is important keep in mind that EF users that have 2 DPs cannot charge the via AC power while connected to the DVH. AC charging id disabled.
EF users either have to purchase 2 EcoFlow Smart Generators which will charge the DPs via DC current through the rear battery ports which turns the DPs on and off automatically as required depending on the DPs state of charge (SOC)
Example here th-cam.com/video/wr_y7x4_Vkw/w-d-xo.html
Alternatively, EF users can also charge both of their DPs while they are still fully powering the user’s house if a Switch Mode Power Supply (SMPS) is used with ANY gasoline or propane generator a user may already have but it is a third party solution a user would have to purchase which is not sold by EF.
Example here th-cam.com/video/kVEqvLiHx2w/w-d-xo.html
Several of us EF users originally had that same TOTIWO SMPS. Unfortunately, it needs to be turned down from 90 volts to 76 volts so that it is only running at 80% of its rated capacity as per manufacturer's recommendation. At 76 volts, it will only output 1200 watts into the DP and even at 80%, one of these TOTIWO SMPS still failed after 6 months.
So most of us have now switched the 2000 watt Ideal Pusling model set to somewhere between 100 and 108 volts which will provide the 1600 watts the DP is capable of taking.
Link to Ideal pulsing model www.alibaba.com/product-detail/AC-110-240V-to-DC-24V_1600953688263.html
Keep in mind there are power losses with using SMPS as each of mine require 1,875 watts of AC power to output 1,600 watts of DC power into the DP but the benefit is that my DP's can output their full capacity of 3,600 watts rather than the reduced 1,800 watts which is limited by the "pass through" mode that occurs when a DP is connected to an AC power source.

Looking to get a power supply to power both of my DP’s . I probably only need a total of 1200 watts across the two, Can I use just one power supply, if so which one would you recommend?
Why don't you just plug your Delta Pro's AC input into the AC output of the EG4 inverter?
You don't need to buy anything extra that way. Of course DC to AC to DC conversion isn't the most efficient but neither is doing it your way which is still DC to AC to DC.
You even have ECO-Worthy batteries. Our setups are very similar.
Have you used the "Backup Reserve" feature on the Delta Pro? I have noise issues with the AC output when I use it.
That would be convenient! Unfortunately, the Delta Pro's AC input and outputs are disabled when connected to the Smart Home Panel via the Infinity cables.
Riddle me this: “Why not just plug the AC input of the Delta Pro directly into the power strip?”
Panel limitation?
If so that’s a big strike against the Smart Panel, a non-starter in my opinion
Indeed, the Delta Pros disable their AC input/outputs once you connect them to the smart home panel via the infinity cables. The idea is that those cables will handle the AC input to the delta pros and the AC output will come from your house circuit board. It makes sense, but yes would be nice if you still use the AC input and outputs on the Delta pro when connected to the Smart Home Panel.
@@DanielGoodwin-jq1oc Does it also disable the AC input on the DP extra batteries. If not you could charge those via AC from the inverter and those batteries would then keep the DPs charged? I know this might not work but I am really trying to figure this out before I buy the DP extra batteries.
A good question. Unfortunately, there is no AC input on the extra batteries. The batteries can only use the proprietary cable that connects them to the Delta Pro unit. They're essentially useless without an accompanying Delta Pro.
Why in the world you want to do something so inefficient like that. You are converting AC to DC to charge your EcoFlow that will convert the DC back to AC. I don’t get it
Agreed, Its dreadfully inefficient. The only reason you'd do something like this is:
1. You have excess solar capacity (far greater than the 1,600w limit of the Delta Pro)
2. You want to have excess battery capacity (of an external battery bank in addition to the Delta Pro and its 2 extra batteries).
But efficient? No definitely not efficient.
