Startup
This is the transient process between the
Initial Standby
mode and the
Run
mode. Once
the
Startup
mode is complete, module will start powering the grid.
Run
In this mode, module converts the DC energy into AC energy and feeds it to the grid by way
of MPPT.
Module tracks the PV arrays’ maximum power point (MPP) to maximum the output energy.
Standby
In
Run
mode, module will enter into the
Standby
mode if the DC side current is as low as
0A for a while.
Module will continuously check if the PV array meets the grid-connection requirements. If
the module DC startup voltage and the startup time are reached, module will turn into the
Run
mode.
Fault
If a fault occurs during operation, module will enter into 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 MV Station reverts to
Run
mode.
During this period, if you want to start the module manually, first confirm the stop clear
protection program from the LCD panel and then start the module.
If the fault is unrecoverable, stop the MV Station and perform maintenance work. Module will
automatically check if the fault is recoverable.
When a DSP fault or a module fault occurs, never restart the MV Station through
the LCD. Perform a power-off check before reenergizing the MV Station.
Otherwise, the module may be damaged.
Emergency-stop
Stop the module by pressing the emergency stop button inside the monitoring window when
a fault or emergency occurs.
If the module is stopped by the emergency stop button, the AC switches of the MV Station
trip off immediately and the modules will disconnect from the grid. To restart the modules,
release the emergency stop button, push the AC switches to the OFF position, and then
operate according to the normal start process.
Key-stop
When maintenance or service work is required, the MV Station 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, module can keep running but send alarm signal. User can check the
present alarm information through the Working state on the LCD default screen or check the
System Manual
