- اوٽ وولٽtage: گهربل AC آئوٽ پُٽ وول چونڊيوtage (e.g., 230VAC for this model).
5. آپريٽنگ هدايتون
5.1 پاور آن/آف
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 اشارا
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 پاور بچت واري موڊ
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 Connecting AC Loads
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. سار سنڀال
باقاعده سار سنڀال بهترين ڪارڪردگي کي يقيني بڻائي ٿي ۽ توهان جي انورٽر جي عمر وڌائي ٿي.
