Types of solar battery systems
Battery systems can be categorised as separate components, semi-integrated (also known as hybrid) or fully integrated (also known as all-in-one). Sometimes it becomes confusing since some manufacturers may classify their system as all-in-one, but it doesn’t include the solar inverter. Some all-in-one systems can also be modular – the batteries, charge controllers, car chargers are added into a neat stack, so the components can easily be replaced.
DC coupled battery systems

AC coupled battery systems
Many of the DC coupled systems shown above can also be configured to work as an AC coupled system.
