Energy storage during power outages

What happens to a battery during a power outage?

During an outage, you'll run on battery power, recharge daily with solar and top off the battery with the generator when necessary. It’s currently the most powerful of any residential battery storage system on the market, and one battery can provide enough power for starting energy hogs such as large air conditioners or well pumps.

How does a battery backup system work during a power outage?

During a power outage, the battery system automatically kicks in, providing electricity to keep essential appliances and systems running. There are several types of home battery backup systems available, each with its own advantages and limitations. The three main types are lithium-ion, lead-acid, and flow batteries.

Why should you choose a home energy storage system?

With independence from the utility grid, you can avoid the inconvenience of outages without sacrificing your daily routines. Most home energy storage systems provide partial backup power during outages. These smaller systems support critical loads, like the refrigerator, internet, and some lights.

What is a home energy storage system?

Most home energy storage systems provide partial backup power during outages. These smaller systems support critical loads, like the refrigerator, internet, and some lights. Whole-home setups allow you to maintain normal energy consumption levels—but at a cost.
