How does a PowerBank work?

Customers are allocated virtual storage in the PowerBank battery. As their solar panels generate solar power during the day, they can automatically store up to 6kwh or 8kwh of excess or unused power in the battery.

From 3pm to midnight – when grid energy use is generally at its peak – households can draw energy back from the battery to power up their homes. At midnight, any excess power still in the battery is returned to the grid, with the householder paid the standard feed-in tariff.
