1 Waiting
mode
Waiting stage after the inverter is powered on or clearing the alarms.
• When the conditions are met, it enters self-check mode.
• If there is a fault, the inverter enters fault mode.
2 Self-check
mode
Before the inverter starts up, it continuously performs self-check,
initialization, etc.
• When the conditions are met, it enters the grid-tied mode, and the
inverter starts on grid connection.
• If the grid is not detected or the grid fails during checking, and the
back-up function is enabled, it enters the o-grid mode; if the back-up is
disabled, it enters waiting mode.
• If the self-check fails, and faults are detected, it enters fault mode.
• If the self-check fails, and alarms are detected, it enters fault mode.
3 Grid-Tied
mode
The inverter is grid-tied successfully.
• If a fault is detected and back-up function is disabled, it enters fault mode.
• If an alarm is detected and the back-up function is disabled, it enters
waiting mode.
• If the back-up function is enabled, and a fault/alarm that will not inuence
the back up funcation is detected, it enters o-grid mode.

up funcation is detected, it enters fault mode.
• If the back-up function is enabled, and an alarm that will inuence the
back up funcation is detected, it enters waiting mode.
4 O-grid

continues to supply power to the load via BACK-UP port.
• If a fault is detected, it enters the fault mode.
• If an alarm is deteced or the back-up function is disabled, it enters
waiting mode.
