I am also stuck at this point, did you make progress beyond this? I am trying to get the data to mqtt or directly to my emoncms instance

Done thanks. I am using s generic lifepo4 cells with the inverter, when I selected the lithium charging profile I was not able to find where to set the charge voltage. Looks like the profile meant for littium with compatible BMS which mine does not have as am ANT BMS. I then used the lead acid profile but the charge voltage stays at 54v which is the float voltage that I set...it does not get to absorption which is 55.2. Any suggestion on how to address this? Thanks

Mine is also at 3,4 I will also change to 5,6 but can you confirm if you had to shutdown inverter before doing this? Or can it be done while the inverter is supplying power

Are you saying that one may not need the CT? I don't do export to grid, not applicable in my country, so does it mean that I really don't need to install the CT?

I have just installed the 8kw Deye which is similar to sunsynk but I must confess that the guy is pretty loud, louder than the MPP GK that I replaced and it even comes on at lower lower loads. So am wondering is there could be something wrong with my set-up. I have my CT placed quite close to the inverter, could that be the reason? Which of the attached temp triggers the fan? DC or AC?

I have just installed Deye 8kw, but the fan makes significant noise, much more than the MPP GK that was was using before. I am thinking a firmware update might help, please how do I do update on this thing?

I have emoncms already existing and using it with solpi for my current MPP, solpi pulls information from the inverter to the emoncms. Is there a solpiplog like way to pull information from the deye inverter to emoncms?

I am expecting a 8kw Deye as well, as a current MPP user am hoping the experience will be better, especially with LFP charging. I like to get it's data to emoncms, is there a way to achieve this? Also the does it support mqtt?

Am using ANT BMS on my new cells but I noticed over .1v difference between 2 cells, do you experience this as well? Mine is a 8s 24v bank

Thanks @Coulomb for the useful reference when I ran the command below it changed on the inverter but it didn't reset the system back to bulk, is there something else I should be looking at? PBFT27.5

@weber pardon my DIY skills, could you kindly show me with a picture sample of how to run the command via a terminal? and will be good to know how to do the automation on node-red? I already have node-red running on my pi. This seem to be my only option to work around the early float bug on my GK

Looks like we the 3kv users are stuck then. Guess I just keep on with my 27.2 float settings

Did you eventually go for 220v or default 230v? am curious to know the difference in this as well

Hi @weber finally I have my 3024GK back online, do you happen to have the firmware to resolve the early float bug issue?

Hello @weber I noticed that the cell that has the main positive to the inverter has a higher voltage than the rest of the cells, at times it can go as high as 3.7v is this a normal behaviour?

Thanks @weber will give this a trial, my axpert clone does not have option to set current to 2A, the least possible is 20A so I will go the voltage route by reducing the bulk voltage, I guess I will need to reduce the float as well right? Cos my current settings is 27.6/27.2 bulk/float. Yes the battery uses a Daly BMS for LFP and it's rated 60A charge current

@weberSo I got 2 bulbs connected to the 2 cells that moves faster than the rest, but the challenge is that by the time the 2 cells are at above 3.45, the rest will still be at 3.3+ and after a few minutes one of the 2 cells would hit over 3.6 and the BMS stops charging. I recall you mentioned that I can only balance at above 3.4 but in this case the other cells are not getting to that required voltage. When charging is disconnected, the voltage comes back down below 3.4 with the 2 cells having higher voltage than the rest (3.35+). What do you advice I do as a work around about this?

Thanks for this @weber, just one or two clarifications, isn't headlamp designed for 12v and will putting it on a 3.4v battery work? If it will, I have a 12v DC fan, can I use that instead as that is readily within reach as it has alligator clicp. You also said I should do this while charging is still on, how about once the battery is supposedly full (the first cell to hit 3.6v) and I then disconnect charging and then discharge the high cells to bring each cells to the same level, won't that work?

1. Just the words of my battery supplier and other friends that got supplies from him, it is now that I have BMV in place that am also trying to verify the battery capacity independently. 2. Did you get your expected capacity before the BMS low voltage tripped? Perhaps I may just go the difficult route, by paralleling all the cells. Was just hoping for balancing option of the BMS without disconnecting the batteries.

After over a week of integrating BVN, here is my observation: 1. My battery BMS kicks low battery by the time am at about 130Ah depletion status out of 200Ah. 2. Voltage of about 3 strings among the 8 series were 0.04v lesser than rest of the string. I am thinking this is probably why am not getting full capacity and why I can't charge beyond 27.5v, it seem the cells are not balanced. Can Daly BMS balance a cell voltage difference of 0.04v? How do I balance the cells without having to disconnect and parallel all the cells? CC: @weber

This is similar to the MPP 3024GK, it works with 250w X6 at 30v each. It didn't work when I used 4 panels.

This is similar to the MPP 3024GK model and for that model it does work you just need to ensure your Voc is more than 240v

So I have set-up my BMV. It gives me 100% SOC on my battery. Can you confirm if you re-synchronised yours since you indicated you were using it for a different battery before.

Yup it's part of the plan, I have the USB already

Mine is Axpert Variant (felicity) 3kva 9 x 250w sunfit panels connected in 3by3 DIY Lifepo4 battery bank 200Ah with Daly BMS RaspberryPi running emoncms and solpiplog for monitoring SPD and circuit breaker BMV 712 (yet to be installed)
