Procedure
Step 1 Wear proper personal protective equipment (PPE).
Step 2 If the solar inverter is not shut down due to a fault, send a shutdown command on the
SUN2000 app, SmartLogger, or management system. If the solar inverter has shut down due
to a fault, go to the next step.
Step 3 Turn off the AC switch between the solar inverter and the power grid.
Step 4 Measure the DC current of each PV input string using a clamp meter that is set to the DC
position.

Step 5 Open the maintenance compartment door, install a support bar, and use a multimeter to
measure the voltage between the AC terminal block and the ground. Ensure that the AC side
of the solar inverter is disconnected.
Step 6 Turn off all DC input switches of the solar inverter.
Step 7 Wait for 15 minutes and troubleshoot or repair the inverter.

8.3 Routine Maintenance

To ensure that the SUN2000 can operate properly for a long term, you are advised to perform
routine maintenance on it as described in this chapter.
Issue 06 (2020-02-18)
When a solar inverter is faulty, try to avoid standing in front of the solar inverter.
Do not operate the DC switch on the solar inverter before you finish
If the AC switch between the solar inverter and the power grid has automatically
disconnected, do not turn on the switch before the fault is rectified.
Before power-off for troubleshooting, do not touch the energized components of the solar
inverter. Otherwise, electric shocks or arcing may occur.
If the current is less than or equal to 0.5 A, go to the next step.
If the current is higher than 0.5 A, wait until the solar irradiance decreases and the PV
string current decreases below 0.5 A at night, and then go to the next step.
Do not open the host panel for maintenance if the solar inverter is emitting odor or smoke,
or has obvious exceptions.
If the solar inverter does not emit odor or smoke and is intact, repair or restart it based on
the alarm handling suggestions. Do not stand in front of the solar inverter during the
restart.
