max SoC value for Backup from 75% to 90% #213

Closed ThLehmann closed 10 months ago

ThLehmann commented 10 months ago

for balancing the battery in winter it is necessary to keep the battery at a high level. For this, a backup SoC of up to 90% would be desirable. There is currently a limit of 75%

mkaiser commented 10 months ago

Hi,

datasheet says image

currently the range of the input selector is limiting to 75%

    name: Set reserved SoC for backup
    min: 0
    max: 75
    step: 1

I can't remember the reason why we set it to 75%.... (maybe it is something Sungrow changed...)

Can you change the parameter to 100 and give me a feedback, if it works? (Can't test myself - now backup and pretty much no sun the last weeks...)

If it works as expected, I am happy to integrate it :)

ThLehmann commented 10 months ago

Hey, perfect ! yes the 100% works as well but it make not really sense in my opinion, 90% is enough but if 100% is possible its the choise of the user ;) Edit: just noticed that with 100% Backup SoC the battery is forcibly charged from the mains, so it make sense

done - thank you :)
