This modules can read the battery power and soc as well as the total PV power of a Solakon One
Im- and export of DC energy in Wh added (charging / discharging of battery pack)
Daily DC PV production added
obsolete spaces removed

Die openWB benötigt den Gesamtzählerstand. Gibt es da ein Register für?

The Solakon One consists mainly of a 2.1 kWh battery, an inverter and four MPPTs for PV modules. It can be used as a stand alone "Steckersolargerät". Besides the generally needed modules vendor.py, config.py and device.py there are two component modules.
bat.py provides the AC power at the AC plug, the SoC of the battery and the daily DC charging und discharging energies of the battery.
inverter.py provides the total DC power of the PV modules/MPPTs und the daily DC PV production.
The relevant Modbus registers have been taken from
https://github.com/solakon-de/solakon-one-homeassistant-internal/blob/main/stuff/modbud-doc.pdf
The whole set of modules was tested on a Raspberry Pi 3 with a fresh raspbian bullseye lite, current OpenWB 2.1.9 installation and a Solakon One battery. The bat.py module provided correct live data. The inverter.py module was running without error but zero values due to not connected PV modules.
Configure the inverter component "below" the battery component.
