Startup
This is the transient process between the Initial Standby mode and the Run mode. Once
the Startup mode is activated, the inverter will start feeding power to the grid.
Run
In this mode, the inverter converts the DC energy into AC energy and feeds it to the grid by
way of MPPT.
The inverter tracks the PV arrays’ maximum power point (MPP) to maximize the output
energy.
Standby
In Run mode, the inverter will enter the Standby mode if the DC side current is as low as 0A
for a while.
The inverter will continuously check if the PV array meets the grid-connection requirements.
If the DC startup voltage of the inverter and the startup time are reached, it will turn into the
Run mode.
Fault
If a fault occurs during operation, the inverter will enter the Fault mode. LCD panel will
display the fault type with the “Fault” indicator on until the fault is removed After the fault is
removed, the inverter reverts to Run mode.
If the fault is unrecoverable, stop the inverter and perform maintenance work. It will
automatically check if the fault is recoverable.
When a DSP fault or a module fault occurs, never restart the inverter through the
LCD. Perform apower-off check before reenergizing the inverter. Otherwise, the
machine may be damaged.
Otherwise, the module may be damaged.
Emergency-stop
Stop the inverter by pressing the emergency stop button inside the monitoring window when
a fault or an emergency occurs.
The emergency stop button is used to disconnect the AC circuit breakers, the DC load break
switches. Release the emergency stop button with the corresponding key.
Key-stop
When maintenance or service work is required, the inverter turns from the Run mode to the
Key-stop mode after the user sends a stop instruction via the LCD panel.
Alarm Run
In Alarm Run mode, the inverter can keep running but send alarm signal. The user can
check the present alarm information through the Working state on the LCD default screen or
check the latest 200 entries of history alarm information through “Function”-＞ “History
