Abstract:

Currently, solar cells have been developed as a source of electrical energy and packaged in the form of solar panels. Solar panels convert incoming solar energy into electrical energy and generate direct current (DC) electricity. In its development, it is necessary to implement an inverter to convert DC voltage into alternating current (AC). A single phase full bridge inverter is implemented in this research. The inverter is equipped with a step-up transformer to increase the voltage to 220 VAC.  In this study, testing was carried out by varying the frequency value from 40 Hz - 60 Hz and seeing the effect of the output voltage, output current, and efficiency. The test results show the average voltage on 12 watt LED lamps is 187.422 V and 100 watt incandescent lamps is 172.367 V. Tests with a 35 watt fan load variation have an average voltage value of 209.5 V. Based on the test, the average efficiency is obtained.  Based on the test, the average efficiency is obtained. The percentage of the average frequency variation at the inverter output when loaded with 12 watt LED lamps is 77.41 and when loaded with 100 watt incandescent lamps is 55.31. The load variation test when loaded with a 35 watt fan has an average efficiency of 46.44.
