102 Start-up
Check that the inverter is in local control mode, ie, letter L is at
the top row of the control panel display. If not, press the control
panel key
.
Start the inverter by pressing the control panel key
.
Description of the events in a normal starting procedure
After receiving the start command, the inverter goes to the SLEEP mode.
If there is enough DC voltage available, the inverter starts with the START ISU mode after a delay
defined by parameter group 31 (the default delay is 10 minutes).
In this mode the inverter charges the DC capacitors from the AC output and synchronizes to the grid.
The DC contactor closes. The inverter goes to the MPPT mode and starts to produce active power to the
AC output.
When there is not enough DC voltage and/or power available, the inverter goes back to the SLEEP
mode after a delay defined by parameter group 31.
It may be useful to shorten the delays during the start-up temporarily. Wake-up and sleep levels should
match the available DC voltage.
Check that the inverter operates properly from the following
actual value parameters in the master control program:
• 01.34 PV MODULE DC MEAS
• 01.10 AC POWER
• 01.07 AC CURRENT L1.
The DC voltage should have dropped from the open circuit
voltage and the active power should match the line current and
the AC voltage.
Example display:
Stop the inverter by pressing the control panel key
.
Note : Some grid-related functions
like the low voltage ride-through and
grid monitoring will start to work only
after the inverter has been started
and stopped once.
