Zusammenfassung:	One embodiment provides an On-Off grid hybrid portable energy storage device. The device comprises: a solar cell module that receives incident sunlight and converts the sunlight into electric power; a battery that is charged by receiving the electric power from the solar cell module; and a control unit that checks the output voltage of the solar cell module, checks the output voltage of the battery when the output voltage of the solar cell module is greater than a first voltage threshold, starts charging the battery when the output voltage of the battery is greater than a second voltage threshold, and completing the charging of the battery when the output voltage of the battery is greater than a third voltage threshold. Accordingly, charging may be possible even at low light levels. 일 실시예는 태양광을 입사받아 전력으로 변환하는 태양전지모듈; 상기 태양전지모듈로부터 전력을 전달받아 충전되는 배터리; 및 상기 태양전지모듈의 출력전압을 확인하고, 상기 태양전지모듈의 출력전압이 제1 전압임계치보다 크면 상기 배터리의 출력전압을 확인하고, 상기 배터리의 출력전압이 제2 전압임계치보다 크면 상기 배터리의 충전을 시작하며, 상기 배터리의 출력전압이 제3 전압임계치보다 크면 배터리의 충전을 완료하는 제어부를 포함하는 On-Off 그리드 하이브리드 이동식 에너지저장장치를 제공할 수 있다.
