What size should I get?

It should be big enough to serve at least your household’s average evening energy use, but not so big you’re paying for storage you’ll never use.
Your battery installer will assess your household’s average energy use (often using previous electricity bills and/or your smart meter) to find the ideal size for your battery system.
When looking at battery specs, look for the term “usable capacity” (i.e. “14 kWh usable capacity.”) This shows how much energy that battery can store.
Your battery system’s size will also depend on whether you merely want to access free solar energy at night or want enough energy storage to power your home during a blackout.
