설정 및 설치
1. 인버터 장착
Mount the inverter in a dry, well-ventilated area, away from direct sunlight, heat sources, and flammable materials. Ensure sufficient clearance around the unit for proper airflow, especially around the cooling fan vents.

2. DC 입력 연결
- 인버터의 전원 스위치가 OFF 위치에 있는지 확인하십시오.
- Connect the positive (+) cable from your 48VDC battery bank to the positive (+) DC input terminal on the inverter.
- Connect the negative (-) cable from your 48VDC battery bank to the negative (-) DC input terminal on the inverter.
- 연결부가 헐거워지거나 아크가 발생하는 것을 방지하기 위해 모든 연결부가 단단히 고정되었는지 확인하십시오.
3. AC 출력 연결
The inverter features dual GFCI 120VAC outlets. Plug your AC appliances directly into these outlets. Ensure the total power consumption of your appliances does not exceed the inverter's 700W continuous output rating.

4. 원격 제어 (선택 사항)
The inverter supports a remote ON/OFF control via the green terminal block. Refer to the detailed specifications for wiring instructions if using this feature.
작동 지침
- After all connections are secure, switch the inverter's main power switch to the ON position.
- The inverter will perform a self-test, and the indicator lights will show its status.
- Plug your AC appliances into the GFCI outlets.
- To turn off the inverter, first disconnect all AC loads, then switch the inverter's main power switch to the OFF position.
절전 모드
The inverter features an adjustable power-saving mode. Consult the full technical specifications or contact support for details on configuring this feature via the DIP switches or variable resistor.
유지
- 청소: 인버터 외부를 주기적으로 마른 천으로 닦아주십시오. 통풍구에 먼지와 이물질이 없는지 확인하십시오.
- 사이: 모든 DC 및 AC 연결부의 조임 상태를 정기적으로 점검하세요. 연결이 느슨하면 과열 및 손상이 발생할 수 있습니다.
- 배터리 유지 관리: Ensure your battery bank is properly maintained according to the battery manufacturer's instructions.
- 내부 구성 요소: Do not attempt to service internal components. Refer all servicing to qualified personnel.
문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| No AC output, indicator lights off. | Inverter not powered on, low battery voltage, faulty DC connection. | Check power switch, verify battery voltage, inspect DC cables and connections. |
| Inverter shuts down, fault indicator on. | Overload, over-temperature, input over/under voltage. | Reduce AC load, ensure proper ventilation, check battery voltage. Allow inverter to cool down. |
| GFCI outlet trips. | 연결된 기기 또는 배선에서 접지 오류가 감지되었습니다. | Disconnect appliance, reset GFCI. If it trips again, the appliance or its wiring may be faulty. |
