The energy library / Battery storage
Storage can move energy from one part of the day to another. The useful question is how much you can shift, what it costs and what you want the battery to do.
Tesla UK datasheet
Usable kWh tells you how much energy you can store. Daily demand tells you how much you might use.
The charge and discharge limits determine which loads the system can support at the same time.
Tariff savings, solar self-use and power-cut protection each need a different set of assumptions.
