Pylontech US2000C brand new, unable to communicate with it fully

Featured Replies

Hi everyone,

thankyou for reading this

I am new to solar and just got my first US2000c battery pack! I read everyone uses the PbmsTools V2.5FN to look at data from these units with a console RS232 cable, so wired one up!

After hours of messing around this is where I am at, I know my cable works correctly as I can use hyperterminal to connect to it at 115200  8N1 and 'info' returns good data!

But when I try and use the PbmsTools V2.5FN (which is what I believe everyone uses) it just cycles through the com ports and won't come up with any data, just says it can't connect!

I have now tried on a laptop using a usb to rs232 adapter, and on a pc that actually has a old school com port, it is exactly the same results!

So my question is, what am I doing wrong to not be able to get the monitoring tool working?

Many thanks

Andrew
