which information can i get from PylontechBMS in VRM?

i got 4 x us3000C with the "problematic" chips from last year and updated them to the last firmware V1.7 from august 2022.(before first installation)


in VRM i can make widgets with only some informations, like SOC min cellvoltage etc, but most of the fields are empty.


is this a normal behavior, or should i get more informations?

or is it a problem with new pylontech firmware?

after some more reading it seems, that pylontech just isn`t giving those infos from the BMS.

is that right, or can i get these infos somehow?


what other options i have to get in and out kWh from the battery?

VRM gives me wrong values, because i often feed in from the battery also and that is not recognized.

so it looks, that my batteryeffencies is very bad from numbers.

eg: the last 7 days from VRM:

76 kWh into battery and 30 kWh from the battery, but that is not right.

Hello @cacer

I am not sure what you want to get in detail. I read with VRM from my Pylontech stack ( 2 x 7 pcs. US2000B/US2000C

battery-sum-01.jpg

The first master battery is connected thru CAN-bus to Multiplus-II.


For more detailed information I use Pylontech software battery-view with a Windows PC connected thru USB to master batteries. I use one US 2000C with firmware 1.7 and a second US2000C master battery with firmware 1.8 - there is no differnce in detail

Hope this helps you! Servus DayAndNight!

thank you.

i can get the same informations.

i will inspect batteryview again.


i read about "solaranzeige" and the possibility to get more informations out of the pylontech BMS.


i was hoping to get charged and discharged energy from the BMS.

seems impossible without extra software.


thank you again.
