Knowing how energy storage systems integrate with solar panel systems –as well as with the rest of your home or business–can help you decide whether energy storage is right for you. Below, we walk you through how energy storage systems work with solar and what that means for what you can expect to get from your storage system.
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.

DC Coupled Storage. With DC coupling, the DC electricity created by solar panels flows through a charge controller and then directly into the solar battery. There is no current change before storage, and conversion from DC to AC only occurs when the battery sends electricity to your home, or back out into the grid.
