Desperate help needed! Firmware update went wrong
Dear all,
I have a problem with my Pytes batteries.
My system is a Deye Sun8k inverter with 3 Pytes batteries.
Two of them (named A and B) are operting since August 2023 well and the third one (named C) I got delivered last week.When I connected C to the system, master A resulted in an constant accustic alarm with all LED on.
A reset of all batteries didnt help.
Since I read about different firmwares I assumed, that I had the same problem, but then, all went wrong, I started too quick, got in panic and forgot to check system settings and logging of all steps.Step by step as I remember:
I downloaded all files from Pytes and started with “C8 to C16 upgrade guide and firmware” on battery B.
Bootloader and first firmware update to C8 went ok.
Then the battery started with the message “Slave addr request xx”.
The second update to c16 resulted in an error message, that I didnt remember and didnt made any logging of the messages.
I can login, can type in “info”, but in Hyper terminal the slave addr request is constantly showing up.Despite the error message on battery B, I thought, maybe the master battery A must also be upgraded:
I started with the bootloader.
I cannot remember, what message came up (success/error).
Next step I cannot remember either, if I cannot type “login debug” next or if the first firmware update went wrong.Now battery A is showing me no reaction, when turning on.
Only the starting LED is on, no other.
Reset did not help.
On console connection now, I cannot type anything in.Please see attached a picture with the settings, as far I can read out of the batteries.
In the moment, all batteries are still connected to the system, but turned off.
Please (desperate please!) advise, what steps I can do, in order to get battery A working again.
That is my main problem.
In a separate step, what is needed to make all batteries working fine together.Sorry for my bad english 🙈
Thank you very very much for any help!
Kind regards,
Martin

Hi,
First of all C8 and C16 version of E-Box 48100R batteries can’t communicate with each other as shown in picture. it requires firmware update to same version either C8 or C16. It seems your battery(A) still in update mode, you need to send correct firmware version to the battery. no need to type anything in command window only send firmware. after that please tell us all the firmware versions so we can further guide you about firmware update. No need to update any boot.
Note: be careful while update boot loader, updating wrong file to uboot can permanently damage bms board. only do this after coThank you very much for your support and reply.
I borrowed the console cable (usb to serial to rj45) from a friend of mine, who needs it for work.
Another bought cable (usb to rj45) is not working, even on the new battery.
I cannot figure out, if I have received a broken cable or if I need an additional driver (win11 is not complaining).
Today I bought an orginal Pytes console cable, but with 1-4 days delivery time.Tomorrow evening the friend is visiting me, bringing his cable with him and we will try your suggestions.
Please stay tuned!
Thank you very much
Yesterday I tried again with a adapter cable from Delock USB to serial, and a Cisco cable serial to RJ45, as mentioned from a friend of mine. Proper driver is installed.
Battery A and B were disconnected from the Deye inverter during meantime and switched off.
Only Battery C (the new one) is connected to the Deye and is working correctly.Then on Battery B:
Connected battery B as slave1 to battery C as master.
Connected. Can “login debug”.
With “info” I get the data already mentioned in the screenshot/table above.
On this battery, there is the “bootloaderv1.14_GD32F307xC.bin” as I found on the Pytes website.
With “updata” and “Send to host via XModem” I tried to send the firmware “SPBMS16SRPV1.5.28.C16.bin”, but I received the error message “Failed to receive the block start signal of XMODEM. The procedure will be aborted.“Then on Battery A:
Connected battery A as slave2 to battery B as slave1 (which is connected to battery C as master).
Connected cable to console port. Switched on.
Only the LED underneath the power switch is on. All other LED staid off.
Pressing reset did nothing.
No input via Hyper Terminal possible.
You meantioned, that the battery may still in updata mode.
With “Send to host via XModem” I tried to send the firmware “SPBMS16SRPV1.5.28.C16.bin”, which resulted in a “Time out is occured when the xmodem negotation is started.”Today the orginal Pytes USB adapter will be delivered.
Please advise what to do.
Thank you very much for your support.
Kind regards,
Martinuntil you don’t finish update battery A(which failed firmware update), you don’t need to connect it with other batteries. just connect this battery with hyper terminal and send firmware file to it.
give us your location(country/city) and email address.I want to thank Pytes and all the involved Pytes people Rex and Liu for giving me support and help here in the forum and by video call and remote support.
Really great work – all three of my batteries are now working again and working nicely together.
Thank you again!Would be nice if we had some idea as to what was done to fix this problem.
you can contact us, pytesess@pytesgroup.com
give us details of your problem/fault, which battery you have and how many, battery firmware version, what is your your location(country name), we will try to solve your problem asap
I was forwarded to a Pytes technician.
He have me a call, then we had a video call (that he can see, where I have connected the console cable) and in addition we had a remote connection via Teamviewer.
He gave me some instructions, repaired the 2 battery blocks, which were alive, with the same firmware.
On the “dead” block, the key instruction was, that I had to switch the battery on and pressing the reset button in a very quick/short time frame. Then he was able to repair the boot loader first, then the firmware.Very professional and unbureaucratic help from Pytes, thank you again!!
Thanks for the reply. Yes tech support is great.
