At this point, it''s worth noting depth of discharge. This refers to the amount of battery capacity you can use safely. For example, if a 12kWh battery has an 80% depth of discharge, this means you can safely use 9.6kWh. You should never use your battery beyond its depth of discharge as this can cause permanent damage.

Think about the example above of the difference between a light bulb and an AC unit. If you have a 5 kW, 10 kWh battery, you can only run your AC unit for two hours (4.8 kW 2 hours = 9.6 kWh). However, that same battery would be able to keep 20 lightbulbs on for two full days (0.012 kW 20 lightbulbs * 42 hours = 10 kWh).

Domestic battery storage is a rapidly evolving technology which allows households to store electricity for later use. Domestic batteries are typically used alongside solar photovoltaic (PV) panels. But it can also be used to store cheap, off-peak electricity from the grid, which can then be used during peak hours (16.00 to 20.00).
