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.Solar energy provides a good return on investment through the use of unutilised rooftop space and requires minimal.
Off-grid systems allow you to store and save your solar power in batteries for use when the power grid goes down. It is meant to be entirely self-sustaining.
