Hello, pedrohsenas.
◾The initial password is Changeme.
◾Use the initial password upon first power-on and change it immediately after login. Then, use the new password to log in again. To ensure account security, change the password periodically and keep the new password in mind. A password left unchanged for a long period of time may be stolen or cracked. If a password is lost, the device needs to be restored to its factory settings. In these cases, the user is liable for any loss caused to the PV plant.
◾If you enter incorrect passwords for five consecutive times in 5 minutes, your account will be locked out. You have to try again 10 minutes later.
