Imagine being able to store the energy you’ve generated to use later. That opportunity is here, right now.
It's pretty simple, really. The average household consumes more energy in the morning and evening. Battery storage allows you to save any excess energy generated by your solar system (during the day) so you can use it when you need it, rather than it being fed back into the grid.
Apart from the obvious advantage of putting you in control of your power generation, thus saving you money, it offers the additional benefit of being able to supply power to your critical appliances (such as your refrigerator) in the event of a power outage.
