During a power outage, assuming you have a fully charged home battery, you will be able to use most of the 10 kWh of stored energy. However, depending on the battery type, you’ll want to leave a minimum charge of 5-10% on your battery for a couple main reasons:
The implementation of the battery energy storage system will contribute to a more than 5-fold reduction in the occurrence of power outages in the time interval from 3 min to 1.5 h, which will clearly reduce the System Average Interruption Frequency Index and System Average Interruption Duration Index factors.
For most battery systems, there's a limit to how much energy you can store in one system. To store more, you need additional batteries. And, in most cases, batteries can't store electricity indefinitely. Even if you don't pull electricity from your battery, it will slowly lose its charge over time.
Power outages are an occasional nuisance for everyone, but for some people, they're a far too regular occurrence: According to the Energy Information Administration, in 2021, the average U.S. electricity customer experienced 7 hours of electricity interruptions across fewer than two interruption events.
This paper introduces the concept of a battery energy storage system as an emergency power supply for a separated power network, with the possibility of island operation for a power substation with one-side supply.
Comparatively, partial-home battery backup systems usually store around 10 to 15 kWh. Given that power outages are infrequent in most parts of the country, a partial-home battery backup system is generally all you’ll need. But, if your utility isn’t always reliable for power, whole-home battery backup may be the way to go.
