Technical Support

I am a small domestic user with a 10kWh battery. I am advised not to use the SOC below 20%. On a sunny day I would like to use the morning to put as much as available in my electric car, use the car in the afternoon and fill the battery back up to 100% from solar in the afternoon. What are the lowest OK low battery and shutdown levels I can set to get the most out of the battery?
