Commissioning
• The screenshots are for reference only. The actual screens may vary.
• Obtain the initial password for connecting to the solar inverter WLAN from the label on the
side of the solar inverter.
• To ensure account security, change the password periodically and keep the new password in
mind. Not changing the password may cause password disclosure. A password left
unchanged for a long period of time may be stolen or cracked. If a password is lost, devices
cannot be accessed. In these cases, the user is liable for any loss caused to the PV plant.
• Before maintaining the optimizers and PV strings, turn off the AC switch and set the DC
switch to OFF. Otherwise, the PV strings may be energized, resulting in electric shocks.
