The initial password is 00000a. Use the initial password upon first login. 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.   
 
If you enter wrong passwords for five consecutive times and the interval between two consecutive 
passwords is within 2 minutes, your account will be locked out for 5 minutes.
