Are you sure that you have 4 Batteries connected? Which inverter model do you have? E.g. the HYD models just have two battery inputs.

paveltresnak commented 7 months ago

No, I have connected only one battery. Sofar Solar HYD 10KTL-3PH have two batteries inputs.

cschlipf commented 7 months ago

Which Battery Type have you installed and how many Battery modules?

paveltresnak commented 7 months ago

I have one module Amass GTX 3000 with 5 battries.

cschlipf commented 7 months ago

I see. And with the Amass every single battery module counts as a separate battery, right?

I have a BTS-5k battery and here multiple modules connected to one BDU counts as one battery.

I will check the registers...

cschlipf commented 7 months ago

Registers look fine to me. Can you successfully read "Battery Voltage 4" and "Battery Current 4" with feasible values?

paveltresnak commented 7 months ago

Batteries are in one Battery pack with one BMS. home-assistant_2024-03-06T11-35-46.216Z.log

cschlipf commented 7 months ago

From your log I see way more read errors across the bank, which also affect well tested registers. As you have connected the adapter to the RS485 bus, have you properly terminated the bus on the inverter side with a 120 Ohm resistor? See https://homeassistant-solax-modbus.readthedocs.io/en/latest/sofar-installation/#connect-an-rs485-usb-or-ethernet-adapter

paveltresnak commented 7 months ago

No, I do not connected resistor on inverter side. I will try repair it.

cschlipf commented 7 months ago

I am pretty sure this is your problem then. Please terminate the RS485 bus properly.

@wills106 - I suggest to close this issue (I can't close it myself). If a proper termination does not help, the issue can be re-opened again.

wills106 commented 5 months ago

Closing down as no further response in past couple of months.

Feel free to reopen if needed.
