Operation Mode
| Mode | Name | Description |
| 01 | Regular Mode
(Utility Power Priority) |
In utility power priority mode, when the inverter starts, stable power is delivered to the load through the utility bypass, while the battery pack is simultaneously charged—provided the utility power is within normal operating parameters.
If abnormal conditions occur, such as overvoltage, undervoltage, or severe power distortion, the inverter immediately switches to battery mode. Using its internal modules, it efficiently converts stored battery energy into high-quality AC power, ensuring a continuous and uninterrupted power supply to the connected load. |
| 02 | Energy Saving Mode | In energy saving mode, the inverter continuously monitors the load condition during operation.
|
| 03 | Energy Storage Priority Mode | In energy storage priority mode, when the battery is charged by an external source—such as a solar charging system or utility power—reaching a predetermined battery priority start level triggers the inverter to automatically convert stored battery energy into high-quality AC power for the load.
When the battery level drops to a specified battery priority stop value, the inverter continues to supply power to the load via utility bypass voltage regulation, but does not charge the battery. |
