Hi all,

 

I just recently bought a new US3000C to add to my setup. My current setup consists of a:

- Axpert 3KVA inverter

- 2 x US2000

- ICC software for monitoring

I have connected the US3000C to my setup as master and the 2x US2000 as slaves, but ICC does recognise my battery bank. Can the gurus provide me with a detailed guide on how I can get all my batteries recognised by ICC?

Did you buy the new USB Cable required to connect to the US3000c. I got mine from the solar assistant site and it worked with ICC

Hi, you need to update the batteries' bms firmware with a windows computer, specially the us2000 that are older, I know because I have ICC and also had that issue and updating them fixed it, this is the program and upgrades that pylontech provided me, I recomend you ask them since they will provide the lastest version and you should get a upgrade file specific for the us2000 since my batteries are us3000:

Cheers

Thanks for your response. I really appreciate it. What cable did you use to flash your batteries? Can you point me to where I can get one? Also, how are you connecting your US3000C to ICC given that the console port for it is RJ45 while the ICC USB cable is RJ11.

I bought a new USB cable from Solar Assistant as you recommended and it fixed my issue. Thanks a lot for your assistance on this issue.

Thanks for all this information. I've tried to contact Pylontech - [email protected] - regarding the firmware update but they don't respond at all. Did you use another email address or is there a contact form somewhere?

Thanks in advance!

I used [email protected] a couple of months ago and got a quick response, with the latest 'batteryview' software and a (as it turned out, corrupted) zip of the firmware.

It helps them if you can send them the serial numbers of the batteries, along with details of the exact issue you're facing.

If there is no specific issue, the general advice is to NOT update the firmware.  As I understand it, the newer f/w just contains specific bugfixes that overcome specific communications issues with specific inverters.  If you don't have these issues, there's nothing to be gained - the functionality of the battery is the same.  The risk of 'bricking' the battery by attempting a f/w update is not negligible. 

You'll find various versions of the 'batteryview' software in the 'downloads' section of this site (along with various f/w versions).

If you do intend to go ahead with a f/w update, do yourself a favour and read this thread in it's entirety.  🙂
