How Does A Solar Battery Work? | Energy Storage Explained
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.
High voltage or low voltage
On the other hand, other technologies can cover a very broad range of storage sizes without any additional system costs. The flexibility of the high voltage system is more limited – the coverage for the smaller storage sizes will result in a very specific design and the voltage level will probably not be at 400V, but lower.
