It's not just me. The person who started this thread has exactly the same issue as me to the kWh. Coincidence, I think not. I'm guessing every Australian customer is being deceived by Fox. I don't think it's an accident.
I have exactly those batteries and according to the app, website and API have hit 100% on a number of occasions when solar production was under estimated and house load over estimated.
When you hit 100% are you discharging and charging 41.93kwh or 37.7kwh?

Neither, the battery only reports in percent and I haven't been game enough to drop to 0%, waiting for next prolonged outage.

You can read you input and output power a number of different ways. Anyway, you too will find you do not have access to the advertised 41.93kwh. Fox ESS has scammed Australia. They have a decent product. I think was not wise to scam us all.
