How Long Does a Home Backup Battery Last?

Home backup batteries can provide a reliable source of electricity for your household during power outages or in off-grid locations.


The home backup batteries in portable power stations can also reduce your dependence on the utility grid when you add solar panels to capture clean, renewable energy from the sun.

But how long can a home backup battery last when a blackout comes? Will it be enough to see your home through an extended power outage?And what about over the long term? Is it worth the investment?


In this article, we’ll explore the factors determining how much home backup battery capacity you need to keep your household safe during a power outage.


How long a home backup battery can operate without recharging depends on numerous factors. The most crucial are:

Battery storage capacity (when fully charged)

How much electricity you consume

Available charging options


If you’re using a portable power station paired with solar panels, your home backup battery can recharge while it’s running any time during daylight hours.


If you rely solely on AC electricity from the grid to keep your home backup up battery charged, it may run out of juice long before a blackout ends.


If you’re using a portable power station for home backup, its output capacity determines how much electricity can produce at any given time.


For example, a 10 kWh home backup solution can produce up to 10,000Wh of continuous power. Considering the average American household uses about 30 kWh per day or 885 kWh per month, you’d need to look at a high-capacity home backup battery  to backup an entire home.
