6.3 Powering Off the System
Context

After the SUN2000 powers off, the remaining electricity and heat may still cause electric
shock and burns. After power-off, wait 5 minutes before servicing the SUN2000. Always
wear protective gloves when servicing the SUN2000

If the SUN2000 is connected to the battery, ensure that a shutdown command is sent from
the app. Power off the system after the SUN2000 has shut down. If no shutdown command
is sent from the app, the SUN2000 will shut down after the power grid is powered off. The
SUN2000 will wait for 1 minute and restart (not grid-tied) and charge the battery, which
poses an electrical hazard when you turn off the DC switch.

If Off-grid mode is set to Enable and Grid-tied/Off-grid mode switching is set to
Automatic switching for the SUN2000, ensure that a shutdown command is sent from the
app and power off the system only after the SUN2000 has shut down. If no shutdown
command is sent from the app, the SUN2000 will switch to the backup state after the
power grid is powered off, which poses an electrical hazard when you turn off the DC
switch.
Procedure
Step 1 Send a shutdown command from the app. Perform operations by referring to 7.4.3.5 Starting
or Shutting Down the SUN2000 if you log in as installer; perform operations by referring to
7.5.6 Settings if you log in as user.
