Installing an Inverter (support-mounting is used as an example)
1. The antitheft lock is prepared by customers.
2. For details about wall-mounting the device, see the
SUN2000 (8KTL-28KTL) User Manual.
1. Determine the hole positions on the support
based on rear panel dimensions. 2. Drill holes.
3. Secure the rear panel. 4. Mount the inverter on the rear panel.
5. Tighten hexagon bolts. 6. (Optional) Install an anti-theft lock.

industry are recommended.
Ensure that cables cannot
be removed after crimped.

The skid automatically
starts after the ejector
lever is fastened.
1. Pull back the DC input power cables to check whether the cables would be disconnected.
2. If DC input power cables are reversely connected and the DC switch is ON, do not turn off
the DC switch immediately. Otherwise, the equipment may be damaged. You can
disconnect the DC input power cable on the PV string side or wait until the PV string
voltage reduces to a value within the safety range. Then, turn off the DC switch, remove
the positive and negative connectors, and rectify the connection.

5 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.
4 System Power-on
1. Switch on the AC circuit breaker between the SUN2000 and the power grid.
2. Ensure that the DC Switch at the bottom of the SUN2000 is ON.
3. (Optional) Measure the temperatures at the joints between the DC terminals and the connectors.
1. Check that all screws, especially the screws used for electrical connections,
are secured.
Passed □ Failed □
2. Check that all circuit breakers are switched to OFF.
Passed □ Failed □
