A home battery stores electricity from your panels or drawn at off-peak hours, then releases it when you need it. Unlike a portable station it is installed permanently and takes expansion modules, so expandable capacity matters as much as the starting figure. Watch the rated output, which must cover your consumption peaks, and the maximum solar input, which caps how many panels you can connect. The models compared here range from 3 kWh to over 6 kWh.
