Off Grid Solar System
Off-grid systems work independently of the grid but have batteries which can store the solar power generated by the system. The system usually consists of solar panels, battery ,charge controller, grid box , inverter, mounting structure and balance of systems.
An off-grid solar system is one which is not connected to the grid. A grid is like a huge battery bank which is connected to large power generators and end consumers of electricity. It is a network of transmission and distribution lines.
