Hybrid systems characterize themselves by being able to provide electricity from Batteries and the Grid.
Hybrid Systems are in general off grid systems backed up by electricity from the main grid.
Hybrid systems are a solution when the resources are limited, be it small roof, or monetary concerns. The idea behind Hybrid systems is to partially rely on solar produced electricity and compensate the lack of produced electricity by drawing electricity from the main grid. Feed the main grid with the excess of produced electricity is also an option.
