Changing a Password
This topic describes how to change a password on the monitoring panel.
Context
- The initial password is 000001 for Common User, Advanced User, and Special User.
- Use the initial password upon first power-on and change it immediately after login. To ensure account security, change the password periodically and keep the new password in mind. Not changing the initial 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.
- You are advised to change the password at least once every half year to prevent unauthorized use of your account, which affects system security.
