Hello,
I have a SF2400AC and one AB3000X.
I'm using the Home assistant integration, but I noticed the same behavior with the official app (on HEMS).
At 10PM, I put the SF2400AC on "off" because I don't want to discharge during off hours. A 6AM, I put it back on smart for the day.
The issue is here: the battery discharges A LOT during these 8 hours. I usually lose about 16% (2% per hour). 16% of 2880Wh is 460Wh which means the SF2400AC uses around 57W when off.
Is it normal ?
Is it the average consumption of the SF2400AC ?
Because that's a lot.
Here is an illustration from yesterday:
Went off at 10PM with 71%, woke up at 6AM at 55%. The SF2400AC was off for 8 hours.
I reproduced with HEMS by cheating and putting a "charging" session from 10PM to 6AM at 0W. The exact same thing happened.
