At the core of battery energy storage space lies the basic principle of converting electrical power right into chemical energy and, after that, back to electric power when needed. This procedure is helped with by the elaborate operations of batteries, which contain 3 main parts: the anode, cathode, and electrolyte.
Here is a step-by-step breakdown of what happens with a DC-coupled system: Sunlight hits the solar panels and the energy is converted to DC electricity. The electricity enters the battery and is stored as DC electricity. The DC electricity then leaves the battery and enters an inverter to be converted into AC electricity the home can use.
