Setting Monitoring Parameters
1. If no data collector is used, set the following parameters before connecting the SUN2000 to the
power grid. For the other parameter settings, see the SUN2000 (8KTL-28KTL) User Manual. If a
data collector is used, see the SmartLogger1000 User Manual for the parameter settings.
2. The preset password for Common User, Advanced User, and Special User is 000001. Use the
preset password to log in to the SUN2000 for the first time and then change the password to a
new one to ensure the account security.
