This research develops an innovative tool for portable solar power batteries as an energy source, which stores electrical energy in two ways, namely PLN and solar cells. Furthermore, this research is expected to increase tool innovation for more efficient and practical electricity and energy providers. Used, especially for the community. it also uses a 12V battery capacity to test the portable power supply. the results of direct observations of absorption measurements from solar cells can be displayed on the screen SCC (Solar Charger Controller) is a controller between the solar panel, and the battery which prevents it from overcharging with a value that depends on weather conditions. digital power supply, displays the voltage value when the battery is charged using input from the mains display on the display. digital power supply works between electronic devices and sockets. from the electrical outlet, the AC current is converted to DC from the battery will be converted into AC current by the inverter The electricity stored in the battery will be used when the main PLN energy source is disconnected.} }
