How a backup home battery works

Charging from grid and solar

A backup home battery needs energy before it can provide power during an outage or off-grid adventure. People can charge these batteries in several ways. The two most popular methods are using solar panels and the electricity grid. Many modern systems, like the BN PowerPack, support both options. This flexibility means users can fill up their battery with clean solar energy on sunny days or plug into a wall outlet when the weather turns cloudy.

Here’s a quick look at the main charging methods:

People who want to maximize savings often charge their backup home battery during times when electricity rates are lowest. Solar charging offers a green solution, while grid charging provides peace of mind before storms or planned outages.

Inverter and power conversion

A backup home battery stores energy as direct current (DC). Most household devices and appliances use alternating current (AC). The inverter acts as the bridge between stored energy and usable power. When someone plugs in a lamp or a refrigerator, the inverter quickly converts DC into AC. This process happens almost instantly, so there’s no delay when switching to battery power.

Many batteries use advanced inverters that keep energy losses low. For example, lithium iron phosphate batteries, like those found in the BN PowerPack, reach efficiency levels between 90% and 98%. Some systems use DC coupling, which reduces the number of conversions and keeps more energy available for use. Fewer conversions mean less wasted power and longer runtime for essential devices.
