neglectful, please contact Growatt for specific software to clear and reset

When the selection is successful, the inverter will reboot automatically.
2.5.2 Commissioning
After the inverter reboot, LCD will produce the following messages in order:
‘Ser NO: xxx’->’xxxxx’->’FW version’->’Waiting’->’No AC connection’, the
display repeats ’NO Utility’ and LED will be red.
Close the AC breaker or fuse between PV-Inverter and grid. Turn on the DC
switch. The normal operating sequence begins.
Under normal operating conditions the LCD displays ‘Power: xxx.x W’. That is
the power fed to the grid. The LED turns green.
This completes the check.

PV Panel: Provide DC power to inverter.
Converts DC (Direct Current) power from PV panel (s) to AC (Alternating
Current) power. Because Inverter is grid-connected it controls the current
amplitude according to the PV Panel power supply. Inverter always tries to
convert the maximum power from your PV panel(s).
