Uninterruptible Power Supply Using Solar System
Main alternating current (AC) electric power supply is needed by loads continuity. But some times the main supply can be disconnected, so the loads will stop to operate. Using Uninterruptible Power Supply (UPS), the loads can run continuity. Normally, the UPS gets DC supply from rectifier (main AC supply), but in this project the UPS is powered by photovoltaic module, whereas the inverter and transfer switch are controlled by timer and contactor.
