After FW update sensor.battery_charging_power is sometimes wrong

[stalakerob]

Before you create an issue, make sure to update to the current version of modbus_sungrow.yaml

Describe the bug:
After I updated my SH8.0RT-112 firmware to the latest version the battery charing power sometimes peaks to 45kw or higher. My assumption is that the data type of battery power raw has changed so that it can be negative.

Your Sungrow inverter:

• Model: SH8.0RT-112

• The inverter is connected via (mark one)

  • LAN (internal port)
  • [] WiNet-S (LAN)
  • [] WiNet-S (WLAN)

• Are you using a Modbus Proxy (mark one)

  • [] yes
  • no
  • [] I don't know what that is

Home Assistant version:

• Version: 2024-12-5

modbus_sungrow.yaml:

• Version/ time stamp : 2024-11-02
• [] I ensured to use the most recent version

** Inverter Firmware Status:**

• I made sure that the newest firmware is installed via the installers account

I have same issue. I have also exchange the modbus_sungrow.yaml from fwittenfeld and updated the dashboard files. I checked if the sg_signed_battery_power is used. But my Battery Charging Power is not changed. Discharging shows the richt minus values but charging shows something about 60kW. Do I need to set anything else?

Sounds like the replacement didn't catch everything. I'd double-check that first.
Other thoughts:
Did you maybe make a backup copy of the previous file and left it in the same directory? That could result in unexpected issues as well, Home Assistant would try to load them both.
And: did you fully restart Home Assistant after replacing the files?

[BigDi]

You are right, I only replaced the config file in the root of home assistant not in the integration folder.
Now I have to wait for the next sun shine...
