On sunny days, your solar panels will absorb all the daylight, allowing you to power your home. When the sun goes down, less solar energy is captured – but you still need to power your lights at night. What happens at that point?
Without the smart battery, you would switch back to using electricity from the national grid – which costs you money. With a smart battery installed, you can use all the extra solar energy you capture during the day that you don’t use.
So you can keep the energy you generate and use it – or sell it – when you need it most, instead of wasting it. Now, that’s smart.
