Hello . Can you send me please link or any infos where to buy this pytes battery in EU ? Thanks a lot.

For anyone having problems getting the serial cable to work. Here is the pin-out that should work, its based on a Pylontech cable, which these batteries and BMS seemed to be based on. The connection to the DB9 is based on a female, so if you wanted to solder on to a male DB9 you would invert the connections. (5 would goto 1 and 2 would goto 4, for example)

The latest version of the firmware ends in 1.1.3 if anyone is interested. Hyperterminal and TeraTerm seem to be good serial software to use.

I was having issues with using multiple batteries in parallel, the issue is 1 of the 4 was running an older version of the firmware. They must all be on the same version to get communication to work properly.

I'm being told that their battery view software is still coming out and they are testing it.

The latest batteries have an RJ45 console port.

After some probing with a scope I discovered it is wired as per Cisco Serial Cable.

Just for extra info.

 

[wendtc]

where did you get the current firmware file?
which contact do you have? where do you release the software?

 

[wendtc]

where can you get the firmware from?

 

[themizz]

Here is a link that support provided. Use at your own risk, but worked for me.

BMS update flies - Google Drive

drive.google.com

 

[wendtc]

These are the instructions for the firmware update. Do you also have the *.bin file?

 

[themizz]

See .Bin attached within the .zip. Again, use at your own risk.

Why did you upgrade? what does the upgrade solve?

 

[themizz]

I was having closed loop communications problems with my inverter. After checking the firmware version on each of my 4 batteries, one was on a different version. I had to upgrade all 4 to get them all on the same version for the comms to work properly.

Thank you

Guys i have 4 of this batteries and 2 growatts. I know see that i have unequall discharge.
All batteries are in parallel. First growatt is linked with the master (the first bat) and the second it`s linked with the last in the chain.

Any ideeeas on ballancing? All cables are the same length.

 

[themizz]

@mesia can you share a photo? Are you using a busbar ?

 

[mesia]

No busbar. Only cables same length and done as per manual. As per second image they go into idle if no high load!
I think it`s a bms thing. And also can someone tell me how to change the time on them it drives me crazy! Do you want to see graphs?

 

[mesia]

Nevermind here are some graphs! i have many more i only added a few!

 

[mesia]

Only 10 can be attached.

You're gonna need to diagram what your setup is right now but I think you need to have one inverter take it's positive from battery 1 and negative from battery 4, and the other inverter, the exact opposite.

I did exactly that today for the moment 2 bats are at 82% and 2 at 93%. Now the first invertor is positive from bat 1 and negative from bat 4. And the second invertor positive on bat 4 and negative on bat 1.

Look at the voltages on batteries don`t you think the charge is wrong? 53.017v 81% and 53.020 is 91%
Seems to be calculated from remaining mAH. on Bat 1 80468 mAH on Bat 3 is 91206 mAH. The pictures are after the wire change!
