5. 사용 설명서
5.1 전원 켜기/끄기
After all connections are secure and verified, switch the main power button on the inverter to the 'ON' position. The LED indicators will illuminate to show the inverter's status. To power off, switch the button to 'OFF'. A remote control terminal is also available for external ON/OFF control.
5.2 LED 표시등
The 3-color LED indicators provide visual feedback on the inverter's operational status and any potential faults. Consult the product documentation or the specifications table for a detailed explanation of each LED state.
5.3 절전 모드
The power saving mode can be adjusted via a variable resistor. This feature helps reduce quiescent current draw when no load or a very light load is connected, conserving battery power.
5.4 교류 부하 연결
Plug your AC appliances into the inverter's AC output socket. Ensure the total power consumption does not exceed the inverter's continuous power rating (2000W for this model). For inductive loads (e.g., motors, refrigerators), consider their surge power requirements, which can be significantly higher than their running power.
6. 유지관리
Regular maintenance ensures optimal performance and extends the lifespan of your inverter.
- 청소: 인버터를 깨끗하게 유지하고 먼지가 쌓이지 않도록 하십시오. 외부를 닦을 때는 마른 천을 사용하십시오. 액체 세척제는 사용하지 마십시오.
- 통풍: Periodically check that the cooling fan and ventilation openings are clear of obstructions.
- 사이: Inspect all DC and AC connections regularly to ensure they are tight and free from corrosion. Loose connections can cause overheating and poor performance.
- 배터리 유지 관리: Follow the manufacturer's recommendations for your battery bank's maintenance.
7. 문제 해결
인버터가 제대로 작동하지 않을 경우, 다음의 일반적인 문제 및 해결 방법을 참조하십시오.
