Wrong battery SoC in dual battery tower topology

[mlukasek]

Version of the custom_component

0.13.1

Configuration

Power Storage DC 10.0
two battery towers 11,5 kWh each, total 23 kWh

Describe the bug

Recently new firmware in PS DC 10.0 allows connecting and using 2 battery towers together. Everyhting seems to work OK, but SoC is reported wrong in low values. 7% of SoC is reported as 14% by home assistant component. The upper values are OK as 97% is reported as 97%. There was the same bug in RCT power portal until recent update 1.4.5, which corrects this. The Android application reports SoC correctly.
