Waiting stage after the inverter is powered on.
• When the conditions are met, it enters the self-check mode.
• If there is a fault, the inverter enters the fault 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, it enters the off-grid mode and the inverter runs off-
grid; if the inverter has no off-grid function, it enters the wait mode.
• If the self-check is not passed, it enters the fault mode.
The inverter is grid-tied successfully.
• If the grid is not detected, it enters the off-grid mode.
• If a fault is detected, it enters the fault mode.
• If the conditions do not meet grid-tied requirements and the off-grid output
function is not turned on, it enters the wait mode.
When the grid is powered off, the inverter switches to the off-grid mode and
continues to supply power to the load via BACK-UP port.
• If a fault is detected, it enters the fault mode.
• If the conditions do not meet grid-tied requirements and the off-grid output
function is not turned on, it enters the wait mode.
• If the conditions meet grid-tied requirements and and the off-grid output
function is turned on, it enters the self-check mode.
If a fault is detected, the inverter enters the fault mode. When the fault is
