| Working Mode |
| Line priority mode |
The utility power (AC input/City grid) is given priority to supply power to the load, and at the same time automatically charges the battery, and stops charging when the battery is fully charged. Automatically switch battery power supply when there is no mains power |
| ECO mode |
Similar as Line priority mode.When the load power accounts for less than 10% of the inverter power, the inverter will automatically shut down, and when the load power accounts for 11%~100% of the inverter power, it will automatically start |
| Battery priority mode |
Prioritize the use of batteries to supply power to the load. When the battery voltage is higher than the battery recovery voltage, the battery supplies power to the load; when the battery voltage is lower than the battery low-voltage protection voltage, the inverter will automatically switch from the battery power supply to the Utility power supply, and automatically charge the battery after switching to the Utility power supply |
| Generator mode |
Similar as Line priority mode.Generator output should within 165~275vac and 45~65hz. |
| Unattended mode |
Inverter will always under ON or STANDBY status. when battery voltage is low , the inverter will auto shut down AC output and enter STANDBY status. Once battery been charged it back to the restore point, the inverter will restart the AC ouput. |
