The state when the equipment is in the waiting stage after being powered on or
when the power grid is normal and the off grid output function is enabled, and
the off grid output terminal is powered by the power grid.
• 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 it is detected that the grid conditions do not meet the grid connection
requirements, it will enter 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 enabled, it enters the fault 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 it is detected that the grid conditions do not meet the grid connection
requirements and the off grid output function is not enabled, it enters the
fault 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
cleared, it enters the wait mode.
