How Solar Batteries Store and Deliver Power
A solar battery storage system works by capturing the extra energy your solar panels generate during the day and storing it for later use. When your home or business needs power at night or during an outage, the system automatically draws from the battery instead of the grid.
Each solar battery bank connects to your panels and inverter, creating a smart energy system that manages production, storage, and usage efficiently. With professional installation from Mario Castillo Electric, you get seamless performance and dependable power whenever you need it.
