Although a PV array produces power when exposed to sunlight, a number of other components are required to properly conduct, control, convert, distribute, and store the energy produced by the array.
An off-grid solar power system is not connected to any electric grid. It consists solar panel arrays, storage batteries and inverter circuits. Grid connected systems: These solar power systems are tied with grids so that the excess required power can be accessed from the grid. They may or may not be backed by batteries.
Converting DC to AC: Basic Principles of Inverters
Most power supply designs include a section called a rectifier which takes the incoming AC wave and turns it into a seedy DC voltage. But we can''t always rely on an AC input from the building mains power into our system. An inverter is a device that takes a direct current (DC) and turns it into an alternating current (AC).
