| Summary: | Many rural area in Indonesia, for example in North Sulawesi there are 54 <br />
<br />
<br />
<br />
<br />
villages, still have problem about accessibility of electrical energy, thus many <br />
<br />
<br />
<br />
<br />
people are unable to obtain the electricity for lighting. Solar energy can be used <br />
<br />
<br />
<br />
<br />
as alternative energy to solve this problem. Electrical energy is converted from <br />
<br />
<br />
<br />
<br />
radiation of the sun, then it is stored on a battery. In order to use energy from the <br />
<br />
<br />
<br />
<br />
battery, we have to convert DC to AC form. In present work, DC-AC converter <br />
<br />
<br />
<br />
<br />
based on multi vibrator CD 4047B was constructed with average efficiency up to <br />
<br />
<br />
<br />
<br />
46.26%. By using 12 Volt DC battery 5 Ah, 40 watt lamp can be turned on until <br />
<br />
<br />
<br />
<br />
25 minutes. |
