The Solis support was created based on Fox ESS. It looks like the creator missed to adjust the modbus address for SOC, it's 33139 based on a register map I got from solis support. Total discharge energy is also in kWh, not 1/10kWh units.
Every modbus query fails, as all registers need to be read as input registers (code 0x04), instead of holding register.
right now I get the following error: UnboundLocalError: local variable 'power' referenced before assignment Fix it by moving some code around.

There was a problem hiding this comment.
Macht das gleiche ist aber konsistent zu anderen Modulen

Ich habe das Solis-Modul solange verändert, bis es mit meinem Hybrid-Wechselrichter läuft. Siehe Fehlerreport: https://forum.openwb.de/viewtopic.php?p=118743#p118743
Wahrscheinlich brauchen wir auch #1989
