Based on the width of the signal by removing the two phan came to compare. (PWM) inverter was developed by the bug icon has been selected to develop a charging circuit, which is controlled by the IC design, a TL494 PWM control signal, the device switches to regulate the charging cycle has been determined at work from the solar cells at each time of day. The maximum power value is by using the voltage and current signals from these signals and IC TL494 was sent to the Inverter circuit to order the bug icon, battery chargers and IC to the design value of the TL494 voltage depart to return to IC TL494 to reduce or?Increase the value of the frequency and energy from sunlight results in an experiment to determine the effectiveness of the bug icon, Inverter circuit with solar cells as a power inverter to circuit the bug icon. By output from the solar cell is not fixed by the test with battery, 12 volt, 12 volt, 12 Ah and 35Ah. The output power from solar cell Panel and Inverter circuit outputs of the bug icon is not nearby. The duration of the battery 12 volt, 12 Ah full the 62-minute performance of the inverter is equal to 94.46 kanbak icon and the duration of the battery 12 volt 35 Ah full on average, equivalent to 116-minute performance of the inverter is equal to 96.54% bug icon that sizes up the battery capacity (Ah) will affect the battery charge time and affect the performance of the inverter values bug icon. A value that is not less than 80% can be used.
