Hi, thanks for the comment. Yeah... A video explaining BMS setup and connection to a SunSynk inverter is in progress... hoping to have it out in a few days.
Hi thanks for video! If I turn on the first dip switch, there is no connection and if I turn off the first dip switch, there is a connection, but all menu items except "Paralle" are not active. What am I doing wrong?
Hi, did you select the correct COM port (see video at 04:41)? Did you select the matching Device ID that is set on the dip switches? (see video at 05:05)... Device ID should be 1 if only dip switch number 1 is on (left most switch) - you can also check this in the BMS app. What USB to RS485 adapter are you using? Which version of the PC monitoring software are you using? What version of firmware is currently on the BMS?
@@GrantBurton I did all this. I have the same problem as described here at "diysolarforum" tread "JK PB2A16S-20P No Communication". I suspect that the problem is in the adapter. I use Industrial USB To RS485 422 Converter with CH340G Chip. Version of the PC monitoring software 2.8. Frimware BMS I have two versions 15.27 and 15.30.
It could possibly be a faulty or non-compliant adapter... my adapter uses the FT232RL chip and has been working well so far. Let us know if you try a different adapter and if it works.
Dont you have to use the RS485-1 port just left or right of the CAN port on the bms? On the most right there are 2 RS485-2 ports, I had in mind these are only for paralleling
@@GrantBurton ah yes! I didnt think of that, cause I am ll on CANbus with my deye 12kw hybrid :) Btw; for the 100% SOC issue, on DIYforum there is a nice diy project, Ghost Battery, i am going to try this. Together with 15.32
I read a little about that Ghost Battery project however I don't think the 100% SOC issue affects Deye / SunSynk Inverters. When the BMS reports 100% SOC to the Inverter, it still continues to charge the battery until the RCV is reached ... (or at least thats what I've seen on my SunSynk 10kW Single Phase Inverter)
Hy! A lot of people have a great problem with the firmware update. I have 2 2A150A HWV15 with the 15.10 firmware. Everytime i start the update my bms shuts off and nothing happen.... Have anyone suggestions for me? I`ve tryed different computers....different cables.....3 versions of the PC Software... always the same I hope there is a solution for that
Hi, have you tried using the Force Update option when trying to update the BMS? Also, when trying to update your BMS, is anything else plugged into any of the ports? What USB to RS485 adapter are you using?
@@GrantBurton with the force Update Option there is the same behavior. Nothing Else plugged in. I have used 3 types of usb to rs485 adapters. 2 from Amazon and a seplos one

Hi, yes... Andy from The Off-grid garage has a wonderful resource for the software and firmware... here is a link drive.google.com/drive/folders/1i0gqmxzb4OBCts5G0TuFlGNGpP2g12es
The BMS needs to be powered up in order for it to update... I haven't tried it yet (because I installed it into the battery) but from what I've seen others do... the B- needs to be connected to pack negative and the red lead (that comes out of the BMS) needs to be connected to pack positive (the balance leads don't need to be connected).
@@yu.diachenko7889 HI, according to the Jk website, it should be able to operate from 20 to 70 volts. Normally taking 8 - 16 cells, it should be able to run on 24 volts.
It’s a pleasure. For now, I’ve rolled back the firmware to 15.11. Seems the BMS was sending a ‘force charge’ request to the inverter even though the battery was at 100% SOC, and not allowing the battery to discharge. Didn’t have much time to play around.
Small tip. In case you have them parallels. You need to unplugged them but set them to address 1. The master is normally 0 when used.

Hi, to update the BMS using the PC Monitoring Software, the RS485-2 parallel ports need to be used (two ports to the right side).
@@GrantBurton Where we use the rs485-1 port for, near the CAN port?
It's used for communication to an Inverter, if communication over RS485 is being used.

@@GrantBurton yes i have seen all that Videos and asked there also for help but anybody helped… so i think i‘m Stuck with this 15.10 Version forever…
If I come across anything that might help, I'll let you know. At least your BMS is still working, but it would be nice to upgrade to later firmware.
Hi thanks for video, wondering if I could do any update to my HW V11.XV version...?
Hi Martin, I don't think it's possible for us to do it with those versions. I think once JK load the firmware at the factory, that's it.
tried updating mine but it just stay at 0% then nothing happens, could be my bms is bricked?
Does the BMS still connect to the JK Monitoring Software and display all the live numbers with the BMS running?
yes, the bms still connecting to jk monitoring software and displays all datas live. current firmware version is v14.04.
Hi, any idea where to get firmware for my device?
Vendor ID: JK_B2A8S30P
Hardware Ver: V14.XA
Software Ver: V14.06
Hi, yes... Andy from The Off-grid garage has a wonderful resource for the software and firmware... here is a link drive.google.com/drive/folders/1i0gqmxzb4OBCts5G0TuFlGNGpP2g12es
Is it possible to update the BMS if it is not yet connected to the battery(out of the box)?
The BMS needs to be powered up in order for it to update... I haven't tried it yet (because I installed it into the battery) but from what I've seen others do... the B- needs to be connected to pack negative and the red lead (that comes out of the BMS) needs to be connected to pack positive (the balance leads don't need to be connected).
@@GrantBurton thank you for your quick response
@@GrantBurton connected to a 12V battery - it did not start(( how much does it need to start? 48v? Or maybe I have a broken bms?
@@yu.diachenko7889 HI, according to the Jk website, it should be able to operate from 20 to 70 volts. Normally taking 8 - 16 cells, it should be able to run on 24 volts.
you cant upgrade by mobile phone?
Hi, unfortunately not… only by using the BMS monitoring software on a computer.
Thanks Grant
