These benefits are attracting the attention of a growing number of investors. According to Bloomberg New Energy Finance (BNEF), global investment in residential energy storage reached $15 billion in 2022, a 70% increase year-over-year.

The battery is the heart of the home energy storage system and is responsible for storing electricity. Home energy storage batteries usually use lithium-ion batteries, which have high energy density, long service life and good safety.

Battery storage allows you to continue to use solar power at night or on rainy days, which is especially useful for remote areas or areas with frequent power outages. In addition, batteries allow you to power critical equipment, such as medical equipment or communications equipment, during power outages.
