Design, simulation and implementation of a grid tied solar power controller integrated with instant power supply technology

This article represents an intelligent and cost effective grid tied controller which integrates solar PV system with instant power supply (IPS) module to support continuous electrical power flow and supply access power to grid. Here, solar panels are connected to IPS, an electrical device that provides power to the load and battery during the unavailability of grid, through a microcontroller which determines the direction of power flows. When the battery is fully charged it flows to the load directly. During the unavailability of solar energy, load and battery takes power from the grid. Even if grid is not available power flows to load is supplied from the IPS. Moreover, generated excess electricity from solar panel served to the grid at no load and fully charged battery condition. This grid tied controller combines solar PV system with IPS, to reduce cost with combined use of battery and converter unit of IPS.
