Off grid: Ecoflow Delta Pro - Battery Memory Fix
HTML-код
- Опубликовано: 23 ноя 2022
- After using the Delta Pro for 10 months as the sole power supply for my small workshop, the battery started losing capacity. The lights would last all night when I first got the unit, and now only lasts 3.5 hours.
I called Ecoflow customer service and Jhoan advised me to "recalibrate" the unit by charging it fully, and then shut the unit off for an "hour or two", then deplete the battery. Repeat that cycle 2-3 times and if that doesn't fix it, they would escalate the diagnostic process to the next level.
Long story short - It worked!
Thanks for the video:
After calibrating your battery you can also calibrate the BMS by removing all inputs and outputs. Turn off the unit then press & hold the on/off button for 3 seconds. Now your BMS is also calibrated.
This is a new technology. We are going to have issues. The bigger problem is that the are so many reviewers advertising the pro's with short time use. RUclips are full advertisers living on hits and advertising products. We need more people finding issues and resolving them. Thanks for the video!!!
In a few weeks, I will have been using the Delta Pro for 1 year. I'll make a summary video detailing its pros and cons.
Solved this problem as follows with my ecoflow delta pro. Once it reaches 100%, take out the solar input and switch off. Leave it off for about 2 hours. Then switch on and it’s back to normal. To check, (multiple the load X time to discharge ) divided by percentage remaining X 100. The value should be near 3200. Hope this helps everyone.
I've done this two days in a row now and it doesn't work for me. I drained all the way until it powered off (an extra 90 minutes at 720W at 1% charge remaining), then all the way to 100% at 1000W AC (plus an extra hour at 100%), turned everything off and disconnected overnight, woke up and it's still showing about 2000Wh capacity. 8 hours remain on a 260W load. 😐
Does it have to be solar?
I am having the same problem. Will try your solution - thank you for making this video.
It worked first time. Left it charged at 100% and off overnight. It’s now working normal with a capacity estimate close to 3200. You are a life saver !!!
Awesome! Your feedback helps.
Did you charge to 100% with solar or AC?
Thank you for the video. Having the same issue. Will try this in the morning
Thanks for the great video.
Thumbs up! This information needs past along to other EcoFlow owners
Update on yesterdays comment. I run the unit down until it said 1% and 1 minute until power ran out. It went almost another 2 hours with a power draw of 700 watts before shutting down. On recharge, it got to 99.64% and said 10 minutes until fully charged. It sat like that for a few hours before it read 100%. I've now switched off the unit and will start it up again in 3 hours and see what happens.
Interesting...
Mine only charges to 98%
I have a very similar situation with my River 2 Max. The final 1% takes forever to drain and likewise forever to recharge from 99% to 100%. The recalibration process doesn't change a thing.
Update on update. That seems to have solved my BMS problem. Going to let the unit run to zero once again and do a repeat of a 100% charge and shut unit down for a few hours.
I've been told that low wattage drain and low wattage charging causes the BMS to get out of calibration.
Thanks for the comments
Nice. Thanks for tip
Really useful video. I'll try this reset tomorrow. I've noticed my unit charges far too fast and drains far too fast. Hopefully, a battery recalibration is all that's needed.
Hey blaze did this recalibration work for you as well?
I had the same problem with a River Pro, and I’ve seen someone in the forums saying the same of the new River 2. I am really starting to think EcoFlow can’t fix this issue and they know it fully well but can’t admit it as it would cause brand image problems.
I would also like to present a scenario that together with this problem make EcoFlow products unreliable and at most a camping tool. I have an off grid cabin in a remote Island in Italy. I have solar connected to the river pro and a router + security cameras that notify me of any motion detected. Because the battery is cycling everyday (cameras with IR lights at nigh, charging during day) this problem shows up quickly within a week, peaking at 2. By this time capacity has gone so much that the setup which is estimated to run for 60 hours, can’t even make it through the night.
Ok, so what, just reset it right? Turn it off for a few hours then on… except there’s no one there!! The whole reason for the setup is that it can be safely watched for months on end between travels.
1. This problem should not happen
2. The fix should be an app button “recalibrate SoC” that executes the sequence and turns the unit back on when done
3. It’s a HUGE security risk to execute this process, as an attacker could be in action during this time
4. It’s a resource risk, as solar is my only input, it could be that the next days it’s only cloudy and rainy, thus negating the whole point of having energy ready for emergency
5. Even if the unit could be disabled remotely, someone has to be physically present to turn it on!
This is a huge mess and EcoFlow is not taking responsibility, mostly because RUclips reviewers aren’t bringing it up loud enough to force a response
Very good points. Thanks!
I have a delta pro and have been experiencing this issue as well. I'll be making a video about it as a follow on to my first one. It seems like all of these products have some kind of critical flaw or two.
Battery Calibaration Recap...
1) Charge DP to 100%
2) Remove ALL inputs/outputs.
3) Turn DP OFF for 1-2 Hours.
4) Trun DP ON.
5) Batteries should now be recalibrated.
BMS Calibaration (after battery calibration)...
1) Remove ALL inputs/outputs.
2) Turn DP OFF "then" press & hold ON/OFF button for 3 seconds.
3) BMS should now be recalibrated.
Thank you!
Thank you I have had similar issues. Does anyone know a fix for uneven discharge of two DPs with the 240 hub?
Wonderful! I have been suspecting this myself - I have one extra battery and my main Delta pro seems to reach 100% charge faster than the extra battery which will be about 82% at that time. Main unit seems to discharge faster also reaching 20% when the extra battery stil reads 54%. I will try the calibration method and see if that balances things better. Thanks!
I have a new delta pro, and I have another one that has a 121 overload code. They sent me a replacement and I have the broken one. I'm thinking I an fix it, as it's probably the inverter. Also, I'm thinking I can use the other one as a battery. It still takes a charge and shows the voltage. I just can't plug stuff into it. However, I'm thinking I can link it as a battery. Any opinion or anybody know about a fix for the 121 code?
GREAT video!!!!..... Quick question, What if you have one or two external batteries attached and you need to do a reset. Do you leave the external batteries attached while you do the reset or do you disconnect the external batteries? Thanks!!!
Hi, you must disconnect everything to do the reset. But only for an hour.
Thank you for the video I'm going to try that on mine are you not supposed to draw the battery down 0? I see since you usually sits yours to 10%
I keep my DP set to shut down at 10%, but for this fix, you need to run the battery all the way down to 0%.
I set my ac charge limits to 10% and 90% from day one. Smart gens come on at 20% and off at 90%.
Thanks for the vid. I'm going to try this with mine. I'm interested to know how long it goes before needing to be recalibrated again.
I'll let you know!
After a month, I recalibrated it again. It didn't actually need it too bad, but was showing some signs that the capacity wasn't as strong as it should be.
@@bladeslicemaster5390 I'm seeing the same thing. Might need to become a monthly or quarterly maintenance item to keep the capacity up. I wonder if there could be a software update that would improve this.
I'm guessing the problem wasn't the batteries,it was your BMS.
When you recalibrated it you recalibrated the BMS.🤔
Yes, not battery memory, just a joke of an energy counter internally. LiFePO4 very difficult to measure state of charge and cannot trust % reading. Dont forget to also include internal power consumption used when inverter is on.
I’m having the same problem with my Delta Max
i have the very same issue , i must have done a firmware update at about 60% battery , not thinking much of it , like you , i seem to have lost the about 40
% , my Max 2000AH , only produces incl. inverter 850 WH ... 😪😪 WHAT did you do in fixing yours if you have ?
Mine lost about 40% runtime after a firmware update.
hey @timcat1004 , i have the very same issue as yours , i must have done a firmware update at about 60% battery , not thinking much of it , like you , i seem to have lost the about 40
% , my Max 2000AH , only produces incl. inverter 850 WH ... 😪😪 WHAT did you do in fixing yours if you have ?
Guess I’ll try this. I came home after a week vacation to find my car’s solar setup with a EcoFlow Delta Mini was completely drained. I didn’t have anything plugged in but the solar panel.
Going through some troubleshooting now as I’m very confused 😵💫
Edit: it even drains without the panel plugged in so it’s definitely the battery that’s the problem
Was the inverter on? Mine does not drain when the inverter is off.
Nice shop! How did you install that breaker box and breakers to work with the Delta Pro so that it can run your shop without having extension cords all over the place?
Thanks! Take a look at my first video called, "Ecoflow Delta Pro Off Grid". It shows more detail on how I set up the unit for use off grid.
@@bladeslicemaster5390 Check this out, he just posted this today, exactly what I am trying to do! Wow! ruclips.net/video/uyKZwc_2RP0/видео.html
@@cyberprepper Thats a great video and essentially what i did in my shop, thanks!
Mine is brand new and it's doing the same thing.
Now you know how to "fix" it!
Mine is less than a month old of 24/7 use connected to 1000W of solar and powering/acting as a UPS for my desktop/server/network/cameras/freezer/monitors/etc. I'm having the same issue. Based on the estimated time remaining, the state of charge, and current load, I get approximately 2,000 Wh of capacity, not 3600. I'll be doing this "fix" tonight to try and remedy the issue.
@@assortedmountainlife One thing I've learned since posting this video is that the battery capacity doesn't actually go down. It's just that the BMS is reporting the capacity incorrectly. There is much more capacity available when the counter reaches 1%, sometimes hours of additional operation. Resetting only syncs the BMS with the actual battery capacity.
@@bladeslicemaster5390 Good to know, thank you!
This video should have taken 1 minute. Panning around to show that the lights are on and panning with a flashlight to show they are off and repeating yourself and the process over and over again, is absolutely ridiculous. I mean seriously, WTF??? Good info, but for the love of God, just get to the point!
I wouldn't recommend my other videos to you then! Lol
watch at 2x with captions on :)
Im sure his wife says the same thing when he’s done in less than a minute. Sometimes in life we want the details and the proof. He did a good job.
@@assortedmountainlife - That's what I did, 2x w/captions was less painful. YT should add 3 & 4x speed lol
